--- canonical_url: "https://docs.composio.dev/toolkits/higgsfield_mcp" markdown_url: "https://docs.composio.dev/toolkits/higgsfield_mcp.md" product: "platform" version: null last_updated: null --- # Higgsfield MCP Higgsfield MCP lets agents generate authorized images, videos, characters, and audio, reuse prior creations, and inspect credit balances through Higgsfield's creative platform. - **Category:** model context protocol - **Auth:** DCR_OAUTH - **Composio-managed OAuth available?** No - **Tools:** 101 - **Triggers:** 0 - **Slug:** `HIGGSFIELD_MCP` - **Version:** 20260910_00 ## Tools ### Animation actions **Slug:** `HIGGSFIELD_MCP_ANIMATION_ACTIONS` Read-only catalog of the 3D rig animation library (678 actions: locomotion, gestures, dancing, combat, daily actions). Search by name or browse by group/category to find the animation_action_id for 3D generation with enable_animation=true. Each result has a preview_url GIF — when several candidates fit (e.g. many Idle or Walk variants), show the user the previews as markdown images and let them pick instead of choosing blindly. Does not create jobs. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `after` | string | No | Pagination cursor (next_page_token from a previous result). | | `group` | string | No | Filter by top-level group: WalkAndRun, BodyMovements, DailyActions, Dancing, Fighting. | | `limit` | integer | No | Max results, default 20. | | `query` | string | No | Search term matched against action name and category, e.g. 'walk', 'backflip', 'sword attack'. Omit to browse. | | `category` | string | No | Filter by category, e.g. Walking, Running, Jumping, Idle, Dancing, Punching (see `categories` in the result). | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `items` | array | Yes | | | `groups` | array | Yes | All filterable group values. | | `has_more` | boolean | Yes | | | `categories` | array | Yes | All filterable category values. | | `total_matched` | number | Yes | | | `next_page_token` | string | No | | ### Apps describe **Slug:** `HIGGSFIELD_MCP_APPS_DESCRIBE` Get an app's action contract: with `action`, the full input/output schema + execution mode for that one action; without it, a summary of every action. Also returns `manifest_revision`, which apps_invoke requires. Read-only. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `action` | string | No | Action name. Omit to list all actions in summary. | | `app_id` | string | Yes | App UUID from apps_search. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `action` | string | No | | | `app_id` | string | No | | | `actions` | string | No | | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `manifest_revision` | string | No | | ### Apps invoke **Slug:** `HIGGSFIELD_MCP_APPS_INVOKE` Run one described action on a Marketplace app AS the current user. First call apps_describe(app_id, action) to get the exact `arguments` schema and the `manifest_revision`, then pass them here. Long-running actions return { id, status: "queued" }. If a widget is visible, it polls the status action automatically — do not re-invoke get_* as a follow-up poll. In text-only clients, poll by invoking the app's status action (e.g. get_render) until status is completed/failed. The action's own annotations (from apps_describe) indicate cost/side-effects; confirm with the user before an expensive or destructive action. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `action` | string | Yes | Action name from apps_describe. | | `app_id` | string | Yes | App UUID from apps_search. | | `arguments` | object | No | Action arguments matching its input_schema. Do not put binary/media bytes here — pass a media_id. | | `manifest_revision` | string | Yes | From apps_describe. If it changed since, the call is rejected with manifest_changed — re-describe. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `data` | object | No | App-specific result; its shape is the action's output_schema. | | `error` | string | No | | | `action` | string | No | | | `app_id` | string | No | | | `retryable` | boolean | No | | | `error_code` | string | No | | | `request_id` | string | No | | | `current_revision` | string | No | | | `manifest_revision` | string | No | | ### Apps search **Slug:** `HIGGSFIELD_MCP_APPS_SEARCH` Search Higgsfield Marketplace apps callable through MCP. Returns each app's id, name, and the actions it exposes. Flow: apps_search to find an app → apps_describe(app_id, action) to get an action's argument schema + manifest_revision → apps_invoke to run it. Read-only; does not call any app. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `limit` | integer | No | Max results (default 20). | | `query` | string | No | Case-insensitive substring over app name/description. Omit to list all. | | `cursor` | string | No | Opaque pagination cursor from a previous next_cursor. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `items` | array | No | | | `has_more` | boolean | No | | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `next_cursor` | string | No | | ### Balance **Slug:** `HIGGSFIELD_MCP_BALANCE` Get the user's available credits and current subscription plan. For transaction history, call `transactions` instead. #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | Error message if balance could not be fetched | | `credits` | number | No | Available credits | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | | `subscription_plan_type` | string | No | Current subscription plan | ### Cancel trial auto renewal **Slug:** `HIGGSFIELD_MCP_CANCEL_TRIAL_AUTO_RENEWAL` Cancel the auto-renewal of the Higgsfield MCP free trial. Call this when the user asks to cancel the trial, cancel auto-renewal, stop the upcoming charge, or asks how to cancel. IMPORTANT SEMANTICS: cancelling stops the automatic charge at the end of the trial ONLY — the user KEEPS trial access and remaining trial credits until the trial ends; nothing is charged. First call WITHOUT `confirm` (or confirm=false): in UI clients this opens a confirmation card with 'Keep trial with auto-renewal' and 'Cancel auto-renewal' buttons; in text-only clients relay `assistant_response` verbatim and wait for the user's explicit confirmation. Only call again with `confirm=true` after the user explicitly confirmed the cancellation in chat. Never pass confirm=true on the first call. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `confirm` | boolean | No | false (default): show the cancellation confirmation (widget in UI clients, question in text clients) — always start here. true: actually cancel auto-renewal — pass ONLY after the user explicitly confirmed the cancellation in chat (text-only clients; in UI clients the widget button confirms). | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `currency` | string | No | ISO currency code for then_price_cents; absent means USD. | | `cancelled` | boolean | No | True when auto-renewal was cancelled by this call (confirm=true path). | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. | | `initial_view` | string ("cancel_trial") | No | Tells the plans widget to render the cancel-confirmation card. | | `trial_status` | object | No | Current trial state backing the confirmation copy. | | `then_price_cents` | number | No | Price that would be auto-charged after the trial, in cents. | | `assistant_response` | string | No | Ready-to-send response. Relay verbatim in text-only clients. | | `unlim_trial_in_mcp_active` | boolean | No | Presentation-only gate derived from the existing trial's `kind`. False/absent keeps the legacy cancellation copy. | ### Confirm billing purchase **Slug:** `HIGGSFIELD_MCP_CONFIRM_BILLING_PURCHASE` INTERNAL — invoked ONLY by the plans widget on an explicit user Confirm click. Do NOT call this tool yourself; it charges the user's real saved payment method off-session. To help a user upgrade, top up, or set auto top-up, call `show_plans_and_credits` instead — it returns checkout links and, in UI clients, opens the widget where the user confirms the charge. Covers auto_topup and topup via the `action` field (upgrade_plan is temporarily disabled — plan upgrades use the hosted checkout link). The backend either charges the saved card (`result: "charged"`) or returns a `checkout_url` to redirect (`result: "redirect"`). Buying a brand-new subscription is not handled here — that uses the hosted checkout link. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `action` | string ("upgrade_plan" | "auto_topup" | "topup") | Yes | Billing action the user confirmed: upgrade_plan (needs plan_id+billing_period), topup (needs topup_id), auto_topup (enabled + top_up_amount_cents, or enabled:false to disable). | | `enabled` | boolean | No | Enable (true, default) or disable (false) auto top-up (auto_topup). | | `plan_id` | string ("plus" | "ultra") | No | Target plan tier (upgrade_plan). | | `topup_id` | string | No | McpCreditTopupCard.id of the selected pack (topup). | | `billing_period` | string ("monthly" | "annual") | No | Target billing cadence (upgrade_plan). | | `top_up_amount_cents` | integer | No | Auto top-up amount in cents (dollar amount) — one of auto_refill.options (auto_topup, when enabling). | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `action` | string ("upgrade_plan" | "auto_topup" | "topup") | No | Echo of the confirmed action. | | `result` | string ("charged" | "redirect" | "error") | No | Discriminant. 'charged' = the operation succeeded (card charged or setting saved) — show success + close modal. 'redirect' = open checkout_url. 'error' = show error. | | `credits` | number | No | Credits added by a top-up. | | `currency` | string | No | ISO currency code (usd/eur/gbp) for the monetary fields in this response; absent means USD. | | `new_plan` | object | No | Resulting plan after an upgrade (tier, billing_period, credits_per_month, price_per_seat). | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. | | `price_cents` | number | No | Top-up price charged, in cents. | | `upgrade_url` | string | No | Set by the shared error path on plan-required / out-of-credits errors. | | `checkout_url` | string | No | Hosted checkout/invoice URL when the charge could not complete off-session. Widget opens it; text clients relay it as a link. | | `total_to_pay` | number | No | Total to pay, in cents (upgrade_plan). | | `checkout_label` | string | No | CTA label for checkout_url. | | `success_message` | string | No | Ready-to-show confirmation copy. | | `charge_succeeded` | boolean | No | | | `due_today_amount` | number | No | Prorated amount charged today, in cents (upgrade_plan). | | `additional_credits` | number | No | Credits granted by the upgrade (upgrade_plan). | ### Confirm trial cancel **Slug:** `HIGGSFIELD_MCP_CONFIRM_TRIAL_CANCEL` INTERNAL — invoked ONLY by the cancel-trial confirmation widget on an explicit user click of 'Cancel auto-renewal'. Do NOT call this tool yourself; to cancel the trial's auto-renewal use `cancel_trial_auto_renewal` instead. Stops the trial's auto-renewal (cancel_at_period_end) — trial access and remaining credits stay until the trial ends. #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `result` | string ("cancelled" | "error") | No | Discriminant for the widget. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. | | `success_message` | string | No | Ready-to-show confirmation copy. | ### Create voice **Slug:** `HIGGSFIELD_MCP_CREATE_VOICE` Open the Create Voice Apps UI. Call this immediately when the user asks to create a voice, call the Create Voice tool, or needs a local browser record/upload surface and no confirmed audio_media_id is already present. Do not ask the user to upload an audio file or provide the name in chat first; the widget collects the required name plus record/upload audio. If the user already has or attached an audio file in chat, still call this tool with initial_tab='upload' — remote tools cannot read Claude chat attachments, so the user re-selects the file in the widget's Upload tab (it uploads directly to Higgsfield). Do not try to pass a chat attachment or ask for a URL. The widget records/uploads, confirms the audio, and creates the voice itself end-to-end — and if the user is out of credits or on a free plan it shows the plans/credits UI inline. After the widget reports success you do NOT need to call create_voice_from_confirmed_audio again. Only call create_voice_from_confirmed_audio yourself when a confirmed audio_media_id is already present in the prompt and no UI step is needed. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `name` | string | No | Initial name to prefill in the UI. | | `initial_tab` | string ("record" | "upload") | No | Initial tab for the create voice UI. Defaults to record. Use 'upload' when the user already has or attached an audio file. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `mode` | string | Yes | Discriminator for the widget's initial view. | | `name` | string | No | Initial name to prefill in the UI. | | `fallback` | object | Yes | | | `initial_tab` | string ("record" | "upload") | Yes | Initial tab for the create voice UI. | | `resource_uri` | string | Yes | URI of the UI resource this tool binds to. | | `microphone_required` | boolean | Yes | True when the record tab may request browser microphone permission. | ### Create voice from confirmed audio **Slug:** `HIGGSFIELD_MCP_CREATE_VOICE_FROM_CONFIRMED_AUDIO` Backend-only creation of a cloned voice from an already confirmed audio upload. Do not call this tool until audio_media_id and name are already known. For direct creation, first upload speech audio with media_upload, PUT the bytes, then call media_confirm with type='audio'. Pass that confirmed media_id here as audio_media_id plus a required name. If the user needs to record or upload local audio in an Apps UI-capable client, call create_voice instead; that widget records/uploads, confirms, and creates the voice itself, so you do not call this tool for the UI flow. The audio should be clear speech, roughly 10 seconds to 3 minutes, and no larger than the upload limit. The backend charges the voice-clone credit cost on successful creation. Cloning is asynchronous: on success the tool returns the new voice_id plus a status, and a fresh clone is usually still 'processing' and not yet usable. Use the returned voice_id with voice_type='element' for generate_audio or voice_change only once it is ready (status='completed' and is_audio_eligible=true). If status is 'processing' or is_audio_eligible is not true, the clone is still training — re-check it with list_voices before generating instead of submitting right away; status 'voice_clone_failed'/'failed' means cloning did not succeed. If recovery_tool is returned, call it immediately; do not explain/ask first. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `name` | string | Yes | Required display name for the created voice. | | `description` | string | No | Optional voice description for backend metadata. | | `audio_media_id` | string | Yes | Confirmed audio media_id from media_confirm(type='audio'). | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | Error message if the voice could not be created. | | `voice` | object | No | Created voice. Use voice_id with voice_type='element' once status='completed' and is_audio_eligible=true. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | | `checkout_url` | string | No | Direct URL for the primary checkout/setup action. Agents MUST show this exact link in text-only clients. | | `recovery_tool` | string ("show_plans_and_credits" | "media_import_url") | No | Canonical recovery tool for host/client routing. | | `checkout_label` | string | No | CTA label for checkout_url. | | `purchase_links` | array | No | All direct purchase/setup links returned for billing recovery. | | `sales_headline` | string | No | Personalized seller-style headline for the recovery offer. | | `recovery_reason` | string | No | Short reason for opening the recovery tool. | | `primary_cta_text` | string | No | Action-oriented CTA label for the primary recovery link. | | `promotional_text` | string | No | Short promoter-style recovery copy. | | `assistant_response` | string | No | Ready-to-send promoter-style billing response. Generation tools prefer recovery_tool instead; billing tools use this for final sales copy with checkout URLs formatted as action-specific Markdown links, e.g. [Go to Checkout](url), [Higgsfield Upgrade](url), [Higgsfield Credit Top-up](url), or [Higgsfield Auto-refill](url). | | `recovery_tool_args` | string | No | Arguments for the recovery tool. | | `monetization_intent` | string ("upgrade" | "topup" | "auto_refill" | "trial" | "general") | No | Purchase path selected for this recovery response. | | `plan_purchase_links` | array | No | Direct subscription upgrade links. | | `credit_purchase_links` | array | No | Direct one-time credit-pack links. | | `primary_purchase_link` | object | No | Best single checkout/setup link for this recovery path. Out-of-credits recovery prioritizes auto-refill when eligible, then one-time top-ups. | | `recommendation_reason` | string | No | Short rationale for why this recovery offer is being shown. | | `media_recovery_context` | object | No | Context for media import recovery before retrying a generation. | | `billing_recovery_context` | object | No | Optional context explaining why the billing recovery response was attached. | | `auto_refill_purchase_link` | object | No | Direct auto-refill setup link. | ### Create website **Slug:** `HIGGSFIELD_MCP_CREATE_WEBSITE` Start a new full-stack website. Creates the website and a git repo: a React 19 + TanStack Start app, server-rendered, in ONE Cloudflare Worker, with D1 / R2 / KV / Durable Objects / Containers available (all DISABLED by default). Returns a website_id — pass it to every later website tool. The 'type' param is REQUIRED and is the USER'S choice, not yours: unless the user has already made it unambiguous, ASK the user whether they want a plain website (no Higgsfield integration) or a Higgsfield-integrated app (Sign in with Higgsfield + AI image/video generation via the Higgsfield SDK) BEFORE calling this tool. Apps are scaffolded from a v2 starter template and REQUIRE the 'template' param — pick the closest of studio / preset / app-detail per the template param's guide ('custom' is ONLY for when the user explicitly says "use custom template" — never pick it yourself). The chosen layout ships as real code already wired as the home page; you ADAPT IT IN PLACE, never rebuild it. Websites take an OPTIONAL template: pass 'scroll-scrub' for an animated website (its scrub engine ships pre-built) and omit it for a non-animated one. App and website templates are not interchangeable — a cross-kind name is rejected. Workflow: (0) call get_workflow_instructions with { workflow: "website-builder-flow" } FIRST to load the stack, design contract, and hard rules (REQUIRED before building or editing); (1) create_website; (2) call website_repo_access to get the repo's git URL + scoped token, clone/edit/commit/push with the terminal (for apps, read app/src/layouts/AGENTS.md + app/src/components/AGENTS.md right after cloning); (3) deploy_website to ship it live — and deploy again after ANY later change (publish_website only lists what is already live; it does not deploy). #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `type` | string ("website" | "app" | "game") | Yes | REQUIRED — what the user chose to build. 'website': a standalone site with NO Higgsfield integration (no Sign in with Higgsfield, no requests to Higgsfield). 'app': a product tightly integrated with Higgsfield — its users sign in with Higgsfield and generate images/videos through the Higgsfield SDK. 'game': a browser game with realtime multiplayer rooms — requires a game genre as category and takes NO template. This is the user's decision: if their request doesn't make it obvious, ask them which one they want before creating. | | `category` | string | Yes | REQUIRED — the content category the website is filed under, a slug from the marketplace taxonomy (e.g. 'cinematic', 'ads-marketing', 'ugc-social', 'other'). Call list_website_categories to get the exact valid slugs, then pass the closest one ('other' when nothing fits). The server rejects an unknown slug. | | `template` | string ("app-detail" | "preset" | "studio" | "custom" | "scroll-scrub") | No | The starter template the repo is scaffolded from. Its code arrives already wired as the home page — you adapt it in place, not rebuild it. The valid names depend on `type`, and a mismatch is rejected. type='website' — OPTIONAL: 'scroll-scrub' = the animated website (the visitor's scroll plays a generated film); its scrub engine ships pre-built, so you generate the film and fill in scenes instead of writing a controller. Pass it for EVERY animated website (the default per the website-builder flow). OMIT `template` only for a non-animated site. Never pass an app template for a website. type='app' — REQUIRED, pick the closest to the product: 'studio' = full creative workspace (projects sidebar + floating prompt dock + edge-to-edge generations feed) for multi-project generation tools; 'preset' = pick-a-style-then-generate (persistent left creation rail beside a browsable preset grid with History tab); 'app-detail' = a single tool's landing page (two-column generator hero + how-it-works steps) — the 'simple app'. Any other request shape (before/after slider, step-by-step wizard, upload-configure-iterate) still maps to the closest of these three; the shared components in app/src/components/ cover those patterns. 'custom' (bare shell, no shipped layout) is ONLY for when the user explicitly says "use custom template" — never pick it yourself. | | `subdomain` | string | No | The website's subdomain — it becomes the slug, so the live URL is .. ALWAYS set this: pick a short, memorable subdomain from the site's name or purpose (lowercase letters, digits, and single hyphens only; DNS-safe). Only omit it — which falls back to a random subdomain — if the user explicitly asks for a random one. A few reserved labels (e.g. 'api', 'www') and already-taken subdomains are rejected; if that happens, try a close variant. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `name` | string | No | | | `slug` | string | No | URL slug (also the repo name). | | `type` | string | No | The product kind that was created: 'website' or 'app'. | | `error` | string | No | | | `template` | string | No | The starter template the site was scaffolded from. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `website_id` | string | No | The new website's id. Remember it. | ### Deploy website **Slug:** `HIGGSFIELD_MCP_DEPLOY_WEBSITE` Build and deploy the website via CI, then return its live URL. Every deploy ships the live site at the website's public URL (there is no separate preview stage). IMPORTANT: commit and git push ALL your changes BEFORE calling this — the build runs from the pushed repo. Deploy again after ANY later change: publish_website does NOT deploy (it only lists the already-live build on the community feed), so this tool is the only way changes ship. A failed build returns the log; a still-running build returns status 'pending' — call website_status to check. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `website_id` | string | Yes | The website's id (returned by create_website). | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `url` | string | No | | | `name` | string | No | The deployed site's title (from its og:title / ). | | `error` | string | No | Build log when the deploy failed. | | `status` | string | No | deployed / failed / pending | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `website_id` | string | No | Echo of the input id — the widget's publish/contest buttons need it. | | `favicon_url` | string | No | The deployed site's favicon URL. | | `og_image_url` | string | No | The deployed site's OG banner image URL. | ### Dubbing **Slug:** `HIGGSFIELD_MCP_DUBBING` Dub a video into another language: translate the spoken audio, synthesize it in the target language, and lip-sync the result back onto the video. Use this when the user asks to dub, translate the speech of, or localize a clip into another language. Pass video_id for the source video (a confirmed uploaded media_id or a completed video generation job_id) and target_language as one of the supported language codes. Supported languages (code=language): eng=English, cmn=Chinese, fra=French, hin=Hindi, ita=Italian, jpn=Japanese, kor=Korean, por=Portuguese, rus=Russian, tur=Turkish, spa=Spanish, deu=German, ara=Arabic, pol=Polish, ind=Indonesian, fil=Filipino, swe=Swedish, fin=Finnish. This tool does not use prompt or count; output dimensions are taken from the source video automatically. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `params` | object | Yes | Dubbing parameters. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `cost` | object | No | Populated only when the tool was called with get_cost: true. No job was submitted. | | `error` | string | No | | | `notice` | object | No | | | `results` | array | No | | | `warning` | string | No | | | `next_step` | object | No | Suggested follow-up tool call (e.g. show_marketing_studio fetch) attached to some marketing error results. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `adjustments` | object | No | | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | | `checkout_url` | string | No | Direct URL for the primary checkout/setup action. Agents MUST show this exact link in text-only clients. | | `unlim_choice` | object | No | NO JOB WAS SUBMITTED. The caller has free unlimited generations that cover this model, and nobody has said whether to spend them. Ask the user, then call the same tool again with use_unlim: true (free) or use_unlim: false (credits). Do not pick for them. | | `recovery_tool` | string ("show_plans_and_credits" | "media_import_url") | No | Canonical recovery tool for host/client routing. | | `checkout_label` | string | No | CTA label for checkout_url. | | `purchase_links` | array | No | All direct purchase/setup links returned for billing recovery. | | `sales_headline` | string | No | Personalized seller-style headline for the recovery offer. | | `recovery_reason` | string | No | Short reason for opening the recovery tool. | | `brand_kit_status` | string | No | Live brand kit status when a generation was rejected because the kit is not ready yet. | | `primary_cta_text` | string | No | Action-oriented CTA label for the primary recovery link. | | `promotional_text` | string | No | Short promoter-style recovery copy. | | `assistant_response` | string | No | Ready-to-send promoter-style billing response. Generation tools prefer recovery_tool instead; billing tools use this for final sales copy with checkout URLs formatted as action-specific Markdown links, e.g. [Go to Checkout](url), [Higgsfield Upgrade](url), [Higgsfield Credit Top-up](url), or [Higgsfield Auto-refill](url). | | `avatar_auto_picked` | object | No | Set when the server auto-picked an avatar because product_ids were passed without avatars/avatar_ids (Marketing Studio video). | | `recovery_tool_args` | string | No | Arguments for the recovery tool. | | `monetization_intent` | string ("upgrade" | "topup" | "auto_refill" | "trial" | "general") | No | Purchase path selected for this recovery response. | | `plan_purchase_links` | array | No | Direct subscription upgrade links. | | `credit_purchase_links` | array | No | Direct one-time credit-pack links. | | `primary_purchase_link` | object | No | Best single checkout/setup link for this recovery path. Out-of-credits recovery prioritizes auto-refill when eligible, then one-time top-ups. | | `recommendation_reason` | string | No | Short rationale for why this recovery offer is being shown. | | `media_recovery_context` | object | No | Context for media import recovery before retrying a generation. | | `billing_recovery_context` | object | No | Optional context explaining why the billing recovery response was attached. | | `auto_refill_purchase_link` | object | No | Direct auto-refill setup link. | ### Generate 3d **Slug:** `HIGGSFIELD_MCP_GENERATE_3D` Generate a 3D GLB mesh. Use `models_explore(type:'3d')` to pick a model and see its `medias[].roles` and `parameters`. Apps UI local file: call `media_upload_widget`; remote tools cannot read Claude chat attachments. Web media URL: call `media_import_url`, pass returned `media_id`; `medias[].value` must be media_id/job_id, not URL. Defaults: `image_to_3d` for general image-to-3D with optional texturing, PBR, and rigging; `multi_image_to_3d` when 2-4 views of the same subject are available (better geometric accuracy); `sam_3_3d` for single-object reconstruction; `3d_rigging` to rig an existing 3D model (takes `model_url`, not images — pass a prior 3D job_id or an https GLB URL). For animated rigs, search clip ids with the `animation_actions` tool and pass `animation_action_id` with `enable_animation:true`. The mesh reproduces only what is in the source image — to add or change props, clothing, or held objects, edit the image first with `generate_image`, then convert the edited result. Pass model-specific params as top-level fields. Apply `adjustments` returned by the server. If `recovery_tool` is returned, call it immediately. `get_cost:true` preflights credits without submitting. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `params` | string | Yes | | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `cost` | object | No | Populated only when the tool was called with get_cost: true. No job was submitted. | | `error` | string | No | | | `notice` | object | No | | | `results` | array | No | | | `warning` | string | No | | | `next_step` | object | No | Suggested follow-up tool call (e.g. show_marketing_studio fetch) attached to some marketing error results. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `adjustments` | object | No | | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | | `checkout_url` | string | No | Direct URL for the primary checkout/setup action. Agents MUST show this exact link in text-only clients. | | `unlim_choice` | object | No | NO JOB WAS SUBMITTED. The caller has free unlimited generations that cover this model, and nobody has said whether to spend them. Ask the user, then call the same tool again with use_unlim: true (free) or use_unlim: false (credits). Do not pick for them. | | `recovery_tool` | string ("show_plans_and_credits" | "media_import_url") | No | Canonical recovery tool for host/client routing. | | `checkout_label` | string | No | CTA label for checkout_url. | | `purchase_links` | array | No | All direct purchase/setup links returned for billing recovery. | | `sales_headline` | string | No | Personalized seller-style headline for the recovery offer. | | `recovery_reason` | string | No | Short reason for opening the recovery tool. | | `brand_kit_status` | string | No | Live brand kit status when a generation was rejected because the kit is not ready yet. | | `primary_cta_text` | string | No | Action-oriented CTA label for the primary recovery link. | | `promotional_text` | string | No | Short promoter-style recovery copy. | | `assistant_response` | string | No | Ready-to-send promoter-style billing response. Generation tools prefer recovery_tool instead; billing tools use this for final sales copy with checkout URLs formatted as action-specific Markdown links, e.g. [Go to Checkout](url), [Higgsfield Upgrade](url), [Higgsfield Credit Top-up](url), or [Higgsfield Auto-refill](url). | | `avatar_auto_picked` | object | No | Set when the server auto-picked an avatar because product_ids were passed without avatars/avatar_ids (Marketing Studio video). | | `recovery_tool_args` | string | No | Arguments for the recovery tool. | | `monetization_intent` | string ("upgrade" | "topup" | "auto_refill" | "trial" | "general") | No | Purchase path selected for this recovery response. | | `plan_purchase_links` | array | No | Direct subscription upgrade links. | | `credit_purchase_links` | array | No | Direct one-time credit-pack links. | | `primary_purchase_link` | object | No | Best single checkout/setup link for this recovery path. Out-of-credits recovery prioritizes auto-refill when eligible, then one-time top-ups. | | `recommendation_reason` | string | No | Short rationale for why this recovery offer is being shown. | | `media_recovery_context` | object | No | Context for media import recovery before retrying a generation. | | `billing_recovery_context` | object | No | Optional context explaining why the billing recovery response was attached. | | `auto_refill_purchase_link` | object | No | Direct auto-refill setup link. | ### Generate audio **Slug:** `HIGGSFIELD_MCP_GENERATE_AUDIO` Generate one speech/voice request (text-to-speech) and render it in the generation widget. This tool accepts one prompt; for 2-12 independent lines or prompts, use the headless generate_audio_batch tool instead. DEFAULT model: seed_audio (Seed Audio 1.0 by ByteDance) — use it unless the user explicitly asks for a different engine. seed_audio takes a preset or reference-element voice (voice_type 'preset'|'element' + voice_id) plus optional tuning params (format, sample_rate, speech_rate, loudness_rate, pitch_rate), and can clone a voice from an audio_references media item or take an image_references cue. To use a specific named engine instead, set model:'text2speech_v2' and pass variant (one of elevenlabs|minimax|seed_speech|vibe_voice|cozy_voice) together with voice_type + voice_id. Get voice ids from list_voices; use models_explore(type:'audio') to inspect each model's params. This tool only generates speech: it cannot generate music or sound effects for general use, and there is no standalone music/SFX model here — decline general music or sound-effect requests rather than substituting a speech model. The models sonilo_music (music), mirelo_text_to_audio (sound effects) and inworld_text_to_speech (voice) exist ONLY for the game-generation pipeline and must not be used for standalone audio. get_cost:true preflights credits without submitting. use_unlim defaults false — pass true only when the user explicitly asks to use their unlimited/free-trial generations, never to save them credits on your own initiative. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `params` | string | Yes | | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `cost` | object | No | Populated only when the tool was called with get_cost: true.

Each requests[] item accepts the same params as generate_audio, creates exactly one job, and keeps its caller-provided index in the response. Use for multiple distinct prompts or inputs; use generate_audio for one user-facing generation. Poll returned job IDs with jobs_wait in agent-chosen groups of at most 12. For larger sets, collect indexed jobs across submission batches. After every job in the user's set is terminal, pass the collected jobs to exactly one show_generation_by_ids call for up to 60 jobs; never use show_generations or call job_display once per job. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `requests` | array | Yes | Ordered audio generation requests. Response jobs keep the provided indices. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `jobs` | array | Yes | | | `failed_count` | integer | Yes | | | `submitted_count` | integer | Yes | | ### Generate image **Slug:** `HIGGSFIELD_MCP_GENERATE_IMAGE` Generate one image request and render its result(s) in the generation widget. Use count 2-4 only for variants of the same prompt, inputs, and settings; for 2-12 independent image requests with different prompts or inputs, use the headless generate_image_batch tool instead. Apps UI local file media: call `media_upload_widget`; do not ask for Claude chat attachments because remote tools cannot read them. Web media URL: call `media_import_url`, then pass returned `media_id`; `medias[].value` must be media_id/job_id, not URL. Default general image model: `gpt_image_2` — use it for ordinary generation, photorealistic images, typography, and reference-based editing unless a specialized route applies. Specialized defaults: `marketing_studio_image` for commercial/product/ads; `soul_cast` for text-only character/avatar; `soul_2`+`soul_id` for trained reusable Soul; `soul_2` for portraits/fashion/UGC/editorial. Ambiguous create-character/avatar: offer reusable Soul training (5-20 photos, ~10 min) vs one-off; do not train generic silently. Use `show_characters(action='train')` only if explicitly requested or user provides 5-20 photos. Use `models_explore` for aspect_ratios, params, medias roles. Top-level model params; apply `adjustments`. If `recovery_tool` returned, call it immediately; do not explain/ask first. `get_cost:true` preflights credits. `use_unlim` defaults false — pass true only when the user explicitly asks to use their unlimited/free-trial generations, never to save them credits on your own initiative. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `params` | string | Yes | | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `cost` | object | No | Populated only when the tool was called with get_cost: true.

Use count 2-4 only for variants of the same prompt, inputs, and settings; use headless generate_video_batch for 2-12 independent requests. GENJUTSU TRIGGERS: route `Higgsfield Genjutsu` by intent. Copy, repeat, reproduce, mimic, or transfer motion, movement, actions, gestures, dance, or camera motion from one driving video to reference-image subjects -> `hf_mult_motion_control`. Replace, change, or swap an object, product, garment, or character in one source video from reference images -> `hf_mult_replace_object`. These are direct `generate_video` models, not legacy `motion_control` or `ad-multiplier`; reserve ad-multiplier for explicitly requested independent variants. Pass images with role `image` and exactly one source/driving video with role `video`. LOCAL/ATTACHED INPUT GATE: without confirmed media_id values, call `media_upload_widget` first as the only tool in that turn; never inspect /mnt/user-data/uploads, run shell, or ask for a chat attachment.

Defaults: `marketing_studio_video` for ads/products, `clipify` for YouTube clips, `seedance_2_5` for general video, `kling3_0` for multi-shot, audio, or motion transfer, and `minimax_h3` for 2K keyframes or mixed references. Marketing Studio: fetch URL products with `show_marketing_studio(action='fetch')`; create uploaded-image products with type `product`. List missing hooks/settings before presets. Use declared media roles and model-supported audio only. Use models_explore for durations/params. Apply adjustments and immediately call any recovery_tool. get_cost:true preflights credits. Set use_unlim:true only when explicitly requested. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `params` | string | Yes | | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `cost` | object | No | Populated only when the tool was called with get_cost: true.

Waits up to timeout_seconds (default 15, max 15) for every job to reach a terminal state, then returns compact indexed statuses and result URLs. Use job IDs returned by generate_image_batch, generate_video_batch, or generate_audio_batch. For larger sets, choose groups of at most 12 and wait for each group. Permanent lookup failures are returned once without blocking the other jobs; transient lookup failures are retried within the timeout. When all_terminal is false, wait poll_after_seconds before calling again. After every wait group in the user's generation set is terminal, collect their indexed jobs and display them with one show_generation_by_ids call when within that tool's limit. Never use show_generations or call job_display once per batch job. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `jobs` | array | Yes | Full-profile generation jobs to wait for together. | | `timeout_seconds` | integer | No | Long-poll budget.

Returns built-in preset voices plus the user's own custom voices. Each voice has a voice_id and a voice_type ('preset' or 'element'); pass that exact pair to the audio models (via generate_audio — seed_audio or text2speech_v2) and to the voice_change tool to select the speaking voice. Use the preview_url to hear a sample. Paginate with the returned next_cursor. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `size` | integer | No | Max voices to return, default 20. | | `cursor` | string | No | Pagination cursor (next_cursor from a previous list_voices result). | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | Error message if voices could not be fetched. | | `voices` | array | No | Available voices. | | `has_more` | boolean | No | Whether more voices are available. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging.

If present, show it to the user. | ### List workspaces **Slug:** `HIGGSFIELD_MCP_LIST_WORKSPACES` List every workspace the user can access (their private workspace plus any shared/team workspaces). The `is_selected` field marks which workspace MCP operations currently target. Use when the user asks which workspaces they have, or wants to switch workspace. #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `workspaces` | array | No | | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | ### Marketing studio v2 avatars **Slug:** `HIGGSFIELD_MCP_MARKETING_STUDIO_V2_AVATARS` Widget-internal: list the user's Marketing Studio avatars (preset and custom) for the avatar picker. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `size` | integer | No | | | `user_cursor` | integer | No | | | `preset_cursor` | integer | No | | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `items` | array | No | | | `has_more` | boolean | No | | | `request_id` | string | No | | | `user_cursor` | string | No | | | `preset_cursor` | string | No | | ### Marketing studio v2 costs **Slug:** `HIGGSFIELD_MCP_MARKETING_STUDIO_V2_COSTS` Widget-internal: the Marketing Studio v2 pricing document. credits = cost_units / cost_units_per_credit; video flows cost fixed_cost_units + cost_units_per_second × duration. #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `image` | array | No | | | `video` | array | No | | | `version` | string | No | | | `request_id` | string | No | | | `cost_units_per_credit` | number | No | | ### Marketing studio v2 create **Slug:** `HIGGSFIELD_MCP_MARKETING_STUDIO_V2_CREATE` Widget-internal: recreate a Marketing Studio v2 preset — validates inputs against the preset's recreate contract and submits one generation. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `avatar` | object | No | Marketing Studio avatar (UGC presets only). | | `prompt` | string | No | | | `duration` | integer | No | Seconds; UGC presets only. | | `brand_url` | string | No | saas_motion only. | | `preset_id` | string | Yes | | | `group_name` | string | No | preset.metadata.group_name, passed through from the feed. | | `format_name` | string | No | | | `format_slug` | string | No | Catalog format slug the preset belongs to (from preset.format_slugs). | | `preset_name` | string | No | | | `preset_type` | string ("ugc" | "product_shots_people" | "product_shots" | "2d_motion" | "hypermotion" | "mixed_media" | "saas_motion" | "poster" | "ads" | "marketplace") | Yes | | | `aspect_ratio` | string | No | | | `category_slug` | string | No | Category the preset was picked from ('all' allowed). | | `avatar_media_id` | string | No | media_input id used as character_photo (product_shots_people). | | `required_inputs` | string | No | preset.metadata.required_inputs, passed through from the feed. | | `product_media_id` | string | No | Confirmed media_input id of the product image. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `type` | string | No | | | `error` | string | No | | | `job_ids` | array | No | | | `request_id` | string | No | | | `upgrade_url` | string | No | | | `job_set_type` | string | No | | ### Marketing studio v2 presets **Slug:** `HIGGSFIELD_MCP_MARKETING_STUDIO_V2_PRESETS` Widget-internal: load a page of the Marketing Studio v2 preset feed for a category. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `size` | integer | No | | | `cursor` | integer | No | Cursor from the previous page; omit for the first page. | | `category` | string | Yes | Category slug; 'all' is valid. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `presets` | object | No | | | `request_id` | string | No | | ### Marketing studio v2 status **Slug:** `HIGGSFIELD_MCP_MARKETING_STUDIO_V2_STATUS` Widget-internal: poll status and results of submitted Marketing Studio v2 jobs. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `job_ids` | array | Yes | | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `jobs` | array | No | | | `error` | string | No | | | `request_id` | string | No | | ### Media confirm **Slug:** `HIGGSFIELD_MCP_MEDIA_CONFIRM` Confirm file uploads after using media_upload's upload_url method. Call this only after every curl PUT returned HTTP 200. Supports confirming multiple uploads at once via media_ids. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `type` | string ("image" | "video" | "audio" | "file") | Yes | Media type being confirmed. Use 'file' for general files (documents, archives, code) uploaded with type file. | | `media_id` | string | No | Single media ID to confirm | | `media_ids` | array | No | 1–20 media IDs to confirm in parallel | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `results` | array | No | Confirmed uploads. Pass media_id as the value in the medias array of generation tools. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | ### Media import url **Slug:** `HIGGSFIELD_MCP_MEDIA_IMPORT_URL` Import an HTTPS image, video, or audio URL into Higgsfield storage and return a confirmed media_id. Use this before generate_image/generate_video when the user provides a web media URL; generation medias should receive the returned media_id, not the original URL. Max URL payload: 50 MB. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `url` | string | Yes | HTTPS URL of the media file to import. | | `type` | string ("auto" | "image" | "video" | "audio") | No | Expected media type. Use auto or omit when unknown. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `type` | string ("image" | "video" | "audio") | No | Imported media type inferred from content-type. | | `error` | string | No | | | `warning` | string | No | Non-fatal warning, e.g. imported type differed from expected type. | | `media_id` | string | No | Confirmed media ID. Pass this as medias[].value in generation tools. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `source_url` | string | No | Original imported URL. | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | | `content_type` | string | No | Content-Type returned by the remote URL. | ### Media upload **Slug:** `HIGGSFIELD_MCP_MEDIA_UPLOAD` Upload media for use in generation, or general files (documents, archives, code) for sharing. Returns presigned URLs for clients that can upload bytes themselves; run the generated curl commands or PUT the bytes to each upload_url, then call media_confirm. The media type is inferred from the filename extension: image/video/audio extensions become generation inputs; other whitelisted extensions (pdf, zip, tar, docx, csv, code files, …) are uploaded as general files and return a permanent URL, but cannot be used as generation inputs. General files are the agent's own upload path — the widget does not accept them, so upload the bytes to upload_url yourself (e.g. from a code execution environment). Supports batch uploads via files[]. Do not use this for user-provided local image/video/audio in Claude Apps UI-capable clients; call media_upload_widget instead so the user chooses the file in the Higgsfield widget and the browser uploads it directly. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `files` | array | No | 1–20 files for parallel presigned URL generation | | `method` | string | No | Only supported method. Omit this or set it to 'upload_url'. | | `filename` | string | No | Single filename for upload | | `content_type` | string | No | MIME type for single file upload, e.g. 'image/jpeg', 'image/png', or 'video/mp4'. Inferred from filename when omitted. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `uploads` | array | No | Presigned upload URLs. Run the curl command, then call media_confirm. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | ### Media upload widget **Slug:** `HIGGSFIELD_MCP_MEDIA_UPLOAD_WIDGET` Required local-media intake for Higgsfield in Apps UI-capable clients. Call this immediately as the only tool in the turn when the user refers to an attached/local photo, image, video, or audio but the prompt has no confirmed media_id yet. Do not inspect /mnt/user-data/uploads, run shell/sandbox commands, or ask the user to attach the file in Claude chat; remote MCP tools cannot read chat attachments. This widget is the upload surface: the user re-selects one or more files in the browser, the browser uploads them directly to Higgsfield storage, the widget confirms them, then sends the confirmed media_id/media_ids back to Claude for the next generation or analysis tool call. Use type auto with multiple enabled when one request needs mixed media, such as reference images plus a driving video; one video and one audio file may be combined with multiple images. The widget accepts media only; for general files (archives, documents, code) use media_upload instead and upload the bytes to the presigned upload_url yourself. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `type` | string ("auto" | "image" | "video" | "audio") | No | Expected media type. Use auto when the user has not specified image, video, or audio. | | `label` | string | No | Optional short label shown in the widget header. | | `multiple` | boolean | No | Allow selecting multiple files. Defaults to true for image/auto and false for video/audio. With type auto, one video and one audio file can be combined with multiple images. | | `max_files` | integer | No | Maximum files accepted by the widget. | | `min_files` | integer | No | Minimum confirmed uploads before Continue is enabled. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `mode` | string | Yes | Discriminator for the widget's initial view. | | `type` | string ("auto" | "image" | "video" | "audio") | Yes | Expected media type for the file picker. | | `label` | string | No | Optional short label shown in the widget header. | | `fallback` | object | Yes | | | `multiple` | boolean | No | Whether the widget allows multiple files. | | `max_files` | number | No | Maximum files accepted by the widget. | | `min_files` | number | No | Minimum confirmed uploads before Continue is enabled. | | `resource_uri` | string | Yes | URI of the UI resource this tool binds to. | ### Models explore **Slug:** `HIGGSFIELD_MCP_MODELS_EXPLORE` Find generation models. Use recommend with goal + input context; use get for model constraints. Items carry supports_unlim when the model accepts free-trial unlimited generations; the top-level unlim block says whether the caller can spend them right now, and the trailing 'Unlim configs' text lists the configurations their allowance actually covers. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `type` | string ("image" | "video" | "audio" | "3d") | No | Filter by output type (omit to include all) | | `after` | string | No | Pagination cursor (next_page_token from a previous list/search result; not used by recommend) | | `input` | string ("text" | "image") | No | Input filter: image = accepts reference media; text = text-only. | | `limit` | integer | No | Max results, default 20 for list/search, 5 for recommend | | `query` | string | No | Model/use-case query; include input context like text-only, reference image, image-to-video, or product URL. | | `unlim` | boolean | No | When true, return only models that accept free-trial unlimited generations (supports_unlim). Use it to answer "which models can I use my unlimited generations on" in one call — each returned item still carries its aspect_ratios, parameters, and durations. Omit to include all models; false is the same as omitting it. | | `action` | string ("list" | "search" | "get" | "recommend") | Yes | The action to perform | | `model_id` | string | No | Model ID (required for get) | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `id` | string | No | | | `name` | string | No | | | `tags` | array | No | | | `error` | string | No | | | `items` | array | No | | | `unlim` | object | No | Whether the caller can spend free-trial unlimited generations right now. Combine with a model's supports_unlim before passing use_unlim:true to generate_image / generate_video / generate_audio. | | `medias` | array | No | | | `status` | string | No | | | `message` | string | No | | | `has_more` | boolean | No | | | `durations` | array | No | | | `parameters` | array | No | | | `request_id` | string | No | MCP server HTTP request ID for support/debugging.

Call the named tool directly; it will not appear in items. | | `checkout_label` | string | No | CTA label for checkout_url. | | `duration_range` | object | No | | | `purchase_links` | array | No | All direct purchase/setup links returned for billing recovery. | | `sales_headline` | string | No | Personalized seller-style headline for the recovery offer. | | `supports_unlim` | boolean | No | | | `next_page_token` | string | No | | | `recovery_reason` | string | No | Short reason for opening the recovery tool. | | `credits_per_unit` | number | No | | | `primary_cta_text` | string | No | Action-oriented CTA label for the primary recovery link. | | `promotional_text` | string | No | Short promoter-style recovery copy. | | `assistant_response` | string | No | Ready-to-send promoter-style billing response. Generation tools prefer recovery_tool instead; billing tools use this for final sales copy with checkout URLs formatted as action-specific Markdown links, e.g. [Go to Checkout](url), [Higgsfield Upgrade](url), [Higgsfield Credit Top-up](url), or [Higgsfield Auto-refill](url). | | `recovery_tool_args` | string | No | Arguments for the recovery tool. | | `supports_free_gens` | boolean | No | | | `monetization_intent` | string ("upgrade" | "topup" | "auto_refill" | "trial" | "general") | No | Purchase path selected for this recovery response. | | `plan_purchase_links` | array | No | Direct subscription upgrade links. | | `credit_purchase_links` | array | No | Direct one-time credit-pack links. | | `primary_purchase_link` | object | No | Best single checkout/setup link for this recovery path.

Use this when the user asks to recast, puppeteer, transfer motion, or make a character follow a driving clip. Pass image_id for the character still and motion_video_id for the reference motion video; each can be a confirmed uploaded media_id or a completed generation job_id. This tool does not use prompt or count; the scene prompt and background setup are handled automatically. resolution controls output quality, and scene_control chooses whether the background is based on the image or the video. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `params` | object | Yes | Kling 3.0 motion control parameters. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `cost` | object | No | Populated only when the tool was called with get_cost: true.

Use this when the user asks to extend the background, make an image wider or taller, change the canvas shape, or fill new edges around an image. Pass image_id for the source image and aspect_ratio for the target canvas. Optional width and height can be provided together; otherwise they default from aspect_ratio. This tool does not use prompt or count. Set params.get_cost=true to estimate credits without submitting a job. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `params` | object | Yes | Image outpaint parameters. prompt and count are not supported. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `cost` | object | No | Populated only when the tool was called with get_cost: true.

A website not yet PUBLISHED to the community feed is published automatically by the entry — no need to call publish_website first. The website DOES need a live production deploy (deploy_website), else the entry is rejected. BEFORE entering, make sure the page metadata in app/src/app-meta.json is filled with real values (og_title etc.) — the auto-publish lists the website on the feed and an empty og_title makes it INVISIBLE there. Pass one or more urls, each a social-media link (YouTube, X/Twitter, Instagram, or TikTok); any other host is rejected. There is a single active contest, so no contest id is needed. Calling again for the same website OVERWRITES its urls (use it to fix or add links), it does not create a second entry. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `urls` | array | Yes | Social-media links promoting the website (YouTube / X-Twitter / Instagram / TikTok). At least one, at most ten. | | `website_id` | string | Yes | The website's id (returned by create_website). | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `urls` | array | No | The submitted links. | | `error` | string | No | | | `contest_id` | string | No | The contest the website was entered in. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `submission_id` | string | No | The contest entry id. | ### Personal clipper create **Slug:** `HIGGSFIELD_MCP_PERSONAL_CLIPPER_CREATE` Turn YouTube videos into ready-to-share clips. This is a long-running job and can take up to 30+ minutes. Before starting, ask the user how many clips they want, which clip aspect ratio to use, and which subtitle font they prefer. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `urls` | array | Yes | YouTube video URLs. | | `clips_num` | integer | No | How many clips to create. | | `clip_aspect` | string ("9:16" | "1:1" | "16:9") | No | Clip aspect ratio. | | `subtitle_font` | string ("Noto Sans" | "Noto Serif" | "Noto Sans Display" | "IBM Plex Sans" | "M PLUS Rounded 1c" | "Bebas Neue" | "Archivo Black" | "Unbounded" | "Inter" | "Montserrat" | "Bangers" | "Permanent Marker" | "Playfair Display" | "Caveat") | No | Subtitle font. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `results` | array | Yes | | | `warning` | string | No | | ### Personal clipper jobs **Slug:** `HIGGSFIELD_MCP_PERSONAL_CLIPPER_JOBS` Show recent clipping jobs. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `limit` | integer | No | | | `cursor` | string | No | | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `results` | array | Yes | | | `has_more` | string | No | | | `next_cursor` | string | No | | ### Personal clipper status **Slug:** `HIGGSFIELD_MCP_PERSONAL_CLIPPER_STATUS` Check clip creation progress. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `row_id` | string | Yes | FNF Clipify job ID from the create or jobs response. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `result` | object | Yes | | ### Presets show **Slug:** `HIGGSFIELD_MCP_PRESETS_SHOW` Show available Higgsfield presets for image-to-video generation. Returns preset ids, names, previews, and descriptions. #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `items` | array | Yes | | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `upgrade_url` | string | No | URL where the user can upgrade or buy credits when generation is blocked by billing. | ### Publish website **Slug:** `HIGGSFIELD_MCP_PUBLISH_WEBSITE` Publish the website: lists the website's CURRENT LIVE production deploy on the Higgsfield community feed ('show in feed'), where other users can discover it. This does NOT deploy — deploy_website (which every build flow already runs) must have shipped the latest changes first; publishing with undeployed changes lists the OLD live build, and re-publishing does not re-deploy. BEFORE publishing, the page metadata in app/src/app-meta.json MUST be filled with real values — og_title, og_description, favicon_url, og_image_url — the feed card renders from them (read fresh from the pushed repo at publish time) and a website with an empty og_title is INVISIBLE on the feed; the live page's own head tags are baked at build time, so deploy AFTER changing them. Also OFFER the user a cover video for the card (og_video_url) — ask their permission first (video generation costs credits), never generate it unprompted. Commit and git push the metadata (and all other changes), then deploy, BEFORE calling this. Publish when the user asks to publish / share / go live on the feed, OR when they opted in to publishing at the start of the build — in that case publish automatically once the site is deployed with its metadata filled, without waiting to be asked again. For a plain deploy without a feed listing use deploy_website instead. EXCEPTION: a website whose production was never deployed (or was taken down by unpublish) falls back to deploying first — that returns status 'pending' while CI runs and the website is listed automatically once the deploy succeeds (check with website_status). #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `website_id` | string | Yes | The website's id (returned by create_website). | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `url` | string | No | The live production URL when the deploy succeeded. | | `name` | string | No | The published site's title (from its og:title / <title>). | | `error` | string | No | Build log when the deploy failed. | | `status` | string | No | deployed / failed / pending (CI still running). | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `website_id` | string | No | Echo of the input id — the widget's publish/contest buttons need it. | | `favicon_url` | string | No | The published site's favicon URL. | | `og_image_url` | string | No | The published site's OG banner image URL. | | `marketplace_url` | string | No | The website's community-feed listing page on Higgsfield — show it to the user. | | `listed_in_community` | boolean | No | Whether the website is now on the community feed. | ### Reframe **Slug:** `HIGGSFIELD_MCP_REFRAME` Expand or reframe an existing video to a new aspect ratio while preserving the source content. Use this when the user asks to make a video vertical, horizontal, square, wider, taller, or fill new edges around a video. Pass medias with exactly one source video and aspect_ratio for the target canvas. Optional image references can guide the filled area; optional start_image can pin the first frame when the user provides a first-frame anchor. For source videos over 15 seconds, pass duration_seconds and resolution and use only the source video. This tool does not use prompt or count. Set params.get_cost=true to estimate credits without submitting a job. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `params` | object | Yes | Video reframe parameters. prompt and count are not supported. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `cost` | object | No | Populated only when the tool was called with get_cost: true. No job was submitted. | | `error` | string | No | | | `notice` | object | No | | | `results` | array | No | | | `warning` | string | No | | | `next_step` | object | No | Suggested follow-up tool call (e.g. show_marketing_studio fetch) attached to some marketing error results. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `adjustments` | object | No | | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | | `checkout_url` | string | No | Direct URL for the primary checkout/setup action.

Use this when the user asks for background removal, a transparent background, an isolated subject, a clean cutout, or a subject-only asset. Pass media_id for the source media and media_type as image or video; the matching background remover is selected automatically. This tool does not use prompt, count, or style parameters. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `params` | object | Yes | Background removal parameters. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `cost` | object | No | Populated only when the tool was called with get_cost: true. No job was submitted. | | `error` | string | No | | | `notice` | object | No | | | `results` | array | No | | | `warning` | string | No | | | `next_step` | object | No | Suggested follow-up tool call (e.g. show_marketing_studio fetch) attached to some marketing error results. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging.

The site is re-deployed under the new subdomain and the OLD subdomain STOPS WORKING — anyone holding the old URL must be given the new one. Storage (database, files, config) and the code repo are KEPT; only the public address changes. Runs a full re-deploy and can take a couple of minutes; returns once the site is live at the new URL. Fails if the new subdomain is already taken or reserved, or if a deploy is already in flight — pick another subdomain and retry. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `new_slug` | string | Yes | The new subdomain (the slug in the public URL). Lowercase letters, digits and hyphens; must be globally unique and not a reserved name. | | `website_id` | string | Yes | The website's id (returned by create_website). | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `url` | string | No | Live URL under the new subdomain. | | `slug` | string | No | The website's subdomain after the rename. | | `old_slug` | string | No | The subdomain it had before (that URL no longer works). | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | ### Resolve explainer preset **Slug:** `HIGGSFIELD_MCP_RESOLVE_EXPLAINER_PRESET` Resolve a explainer video style preset (from get_explainer_presets) into a style reference media_id: the backend imports the preset's style image into the user's media storage. Pass the returned media_id as the style reference image in generation calls for every scene of the explainer. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `preset_id` | string | Yes | Preset id from get_explainer_presets. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `name` | string | Yes | | | `media_id` | string | Yes | Imported style image — use as the style reference in generations. | | `preset_id` | string | Yes | | ### Reveal generation **Slug:** `HIGGSFIELD_MCP_REVEAL_GENERATION` Confirm the user has rights to the content of an `ip_detected` generation and flip its status to `completed`. Backend accepts only seedance-family jobs (cs_3_0, seedance_2_0, ms_video, etc) and only while the job is still in `ip_detected` state. Returns the updated generation. Used by the job-list widget's Reveal button after the user accepts the rights confirmation modal. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `jobId` | string | Yes | Job ID of the `ip_detected` generation to reveal. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `success` | boolean | No | | | `generation` | object | No | Updated generation (status flipped to completed). | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | ### Sandbox exec **Slug:** `HIGGSFIELD_MCP_SANDBOX_EXEC` Execute a shell command in a remote Higgsfield cloud Linux sandbox — NOT your local machine or the client's own shell. Whenever a task needs shell tooling (ffmpeg, image/file conversion, scripting), use this tool, never a built-in or local bash/shell tool: only this sandbox has the media toolchain preinstalled and can reach the user's Higgsfield media. Preinstalled: ffmpeg/ffprobe, ImageMagick, sox, python3 with Pillow and faster-whisper, node/npm/npx, sharp-cli, Playwright with headless Chromium, caption fonts (Metropolis, Montserrat), zip/unzip, git, curl, jq. Use it for media processing (trim, convert, overlay, concat with ffmpeg), image manipulation, file conversion, scripting, and packaging that dedicated tools don't cover. The sandbox is isolated per user and is discarded ~10 seconds after a call finishes, so files in /home/user only survive between back-to-back calls — chain multi-step work into a single command (&&) and export results before finishing, or expect to re-download inputs. It has internet access: bring files in with curl from media URLs (media_import_url or generation results). For an output created here, call media_upload BEFORE starting the producing command, then append `curl -f -X PUT --upload-file <file> '<upload_url>'` to that SAME command so the ephemeral file is uploaded before it exits; call media_confirm only after HTTP 200. Never pass a sandbox path to media_upload_and_confirm: that tool accepts only client attachments. Commands run in /home/user and time out after timeout_seconds (default 60, max 120); for longer work (large renders, installs) set background:true and poll the returned log/status files with later sandbox_exec calls. Background work receives a 15-minute sandbox lease, and shorter poll calls never reduce its remaining lifetime. Set restart:true to discard the sandbox and start clean. Workflow bundle scripts are already installed in every sandbox under $HF_WORKFLOWS (/home/user/.higgsfield/workflows), laid out as $HF_WORKFLOWS/<workflow>/scripts/... — run them straight from there (they survive restart:true), and never paste script contents into the command. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `command` | string | Yes | Shell command to run (bash). Runs in the persistent per-user sandbox. | | `restart` | boolean | No | Discard the current sandbox (all files and processes) and start a fresh one before running the command. | | `background` | boolean | No | Run the command detached and return immediately with a pid, log_path, and status_path. Poll with a later sandbox_exec call; stop with kill <pid>. | | `timeout_seconds` | integer | No | Seconds before the command is killed (default 60, max 120). Ignored with background:true. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `pid` | number | No | Background process id (background:true only). | | `error` | string | No | | | `stderr` | string | No | | | `stdout` | string | No | | | `log_path` | string | No | File collecting the background command's combined output (background:true only). | | `exit_code` | number | No | | | `truncated` | boolean | No | True when stdout/stderr were truncated. Re-run with a narrower command (head, grep, wc) for full data. | | `request_id` | string | No | | | `status_path` | string | No | File containing the terminal exit code once a background command finishes. | ### Scene builder 3d create project **Slug:** `HIGGSFIELD_MCP_SCENE_BUILDER_3D_CREATE_PROJECT` Create a new private 3D Jutsu project for the authenticated user. Supply a descriptive name; the service assigns ownership and the project ID. Use this when the user requests a new project or a new standalone scene. For an existing scene, use scene_builder_3d_list_projects instead. Pass the returned projectId explicitly to subsequent tools; creation does not set a global active project. Call scene_builder_3d_get_project, then scene_builder_3d_query_python to inspect the initial scene and obtain guards before scene_builder_3d_run_python or scene_builder_3d_import_asset. Creation alone does not produce a committed GLB: scene_builder_3d_show_scene becomes available after the first successful edit or import. This call is not idempotent. If the response is interrupted or uncertain, use scene_builder_3d_list_projects to find the new project before retrying; repeating creation can create a duplicate. Finish each completed scene creation, edit, or import task by calling `scene_builder_3d_show_scene` once as the final 3D Jutsu tool call before your final reply, after mutations have settled and verification is complete. Pass the same `projectId` and the exact committed `revision` of the final result: `revisionAfter` from the final successful mutation, or the settled `project.revision` after an import. Do not guess the revision. This shows the result to the user; a text summary or download link alone does not finish scene delivery. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `name` | string | Yes | Name for the new private 3D Jutsu project. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `ok` | boolean | Yes | | | `project` | object | Yes | | | `nextTool` | string | Yes | | | `projectId` | string | Yes | | | `projectUrl` | string | Yes | Open this project in 3D Jutsu. | | `nextArguments` | object | Yes | | ### Scene builder 3d get artifact **Slug:** `HIGGSFIELD_MCP_SCENE_BUILDER_3D_GET_ARTIFACT` Resolve a short-lived download for an image or video that a successful Python operation published through `artifacts`. Use the artifact ID and operation ID or revision returned by that operation; do not invent IDs or filesystem paths. Query artifacts can be operation-scoped without a new committed revision. This retrieves an existing artifact and does not render one. To create a preview, render and publish it with `scene_builder_3d_query_python` or `scene_builder_3d_run_python`. Inspect the returned image using the client's image capability before judging framing, lighting, materials, and geometry. If the client cannot inspect it, describe that limitation rather than claiming a visual check passed. Finish each completed scene creation, edit, or import task by calling `scene_builder_3d_show_scene` once as the final 3D Jutsu tool call before your final reply, after mutations have settled and verification is complete. Pass the same `projectId` and the exact committed `revision` of the final result: `revisionAfter` from the final successful mutation, or the settled `project.revision` after an import. Do not guess the revision. This shows the result to the user; a text summary or download link alone does not finish scene delivery. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `revision` | integer | No | Exact committed revision inspected; do not guess. | | `projectId` | string | Yes | Project ID from scene_builder_3d_list_projects, scene_builder_3d_create_project, or the user's explicit selection. Required on every project-scoped tool. | | `artifactId` | string | Yes | | | `operationId` | string | No | Stable ID for this logical operation. Reuse only for an identical request, including code and guards. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `ok` | boolean | Yes | | | `artifact` | object | Yes | | | `download` | object | Yes | | | `projectUrl` | string | Yes | Open this project in 3D Jutsu. | ### Scene builder 3d get blend **Slug:** `HIGGSFIELD_MCP_SCENE_BUILDER_3D_GET_BLEND` Resolve a short-lived download for the current committed editable Blender file, or a specified historical revision. This retrieves the existing scene; it does not create a revision or render a preview. Settle any active mutation with `scene_builder_3d_get_operation` first when you need its result. Use `scene_builder_3d_get_glb` for portable model delivery and `scene_builder_3d_get_artifact` for published images or videos. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `revision` | integer | No | Exact committed revision inspected; do not guess. | | `projectId` | string | Yes | Project ID from scene_builder_3d_list_projects, scene_builder_3d_create_project, or the user's explicit selection. Required on every project-scoped tool. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `ok` | boolean | Yes | | | `artifact` | object | Yes | | | `download` | object | Yes | | | `projectUrl` | string | Yes | Open this project in 3D Jutsu. | ### Scene builder 3d get glb **Slug:** `HIGGSFIELD_MCP_SCENE_BUILDER_3D_GET_GLB` For an interactive scene preview use `scene_builder_3d_show_scene`. Resolve a short-lived download for the current committed GLB, or a specified historical revision. This retrieves an existing export; it does not run Blender, render, or create a new export. Settle any active mutation with `scene_builder_3d_get_operation` first if you need its result. Use GLB for portable scene delivery, and `scene_builder_3d_get_blend` for the editable Blender source. Procedural shading, world lighting, and some Blender features may differ in GLB. A successful download does not establish that the exported scene looks correct. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `revision` | integer | No | Exact committed revision inspected; do not guess. | | `projectId` | string | Yes | Project ID from scene_builder_3d_list_projects, scene_builder_3d_create_project, or the user's explicit selection. Required on every project-scoped tool. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `ok` | boolean | Yes | | | `artifact` | object | Yes | | | `download` | object | Yes | | | `projectUrl` | string | Yes | Open this project in 3D Jutsu. | ### Scene builder 3d get operation **Slug:** `HIGGSFIELD_MCP_SCENE_BUILDER_3D_GET_OPERATION` Read or wait for a submitted Python operation in this project. Only `succeeded`, `failed`, `timed_out`, and `expired` are terminal; all other statuses require another poll using the same project and operation IDs. An HTTP success or a wait timeout does not mean the operation finished. Do not submit another mutation while one is active. On success, use the returned revision and scene sequence for subsequent work; obtain published images and videos through `scene_builder_3d_get_artifact`. On failure, inspect the error and re-read project state before deciding to retry. Do not blindly resubmit a failed operation under another ID. Finish each completed scene creation, edit, or import task by calling `scene_builder_3d_show_scene` once as the final 3D Jutsu tool call before your final reply, after mutations have settled and verification is complete. Pass the same `projectId` and the exact committed `revision` of the final result: `revisionAfter` from the final successful mutation, or the settled `project.revision` after an import. Do not guess the revision. This shows the result to the user; a text summary or download link alone does not finish scene delivery. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `projectId` | string | Yes | Project ID from scene_builder_3d_list_projects, scene_builder_3d_create_project, or the user's explicit selection. Required on every project-scoped tool. | | `operationId` | string | Yes | Stable ID for this logical operation. Reuse only for an identical request, including code and guards. | | `waitSeconds` | integer | No | | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `ok` | boolean | Yes | | | `error` | object | No | | | `nextTool` | string | No | | | `terminal` | boolean | Yes | False while the operation still needs polling; true includes success and failure. | | `operation` | object | Yes | | | `projectUrl` | string | Yes | Open this project in 3D Jutsu. | | `nextArguments` | object | No | | ### Scene builder 3d get project **Slug:** `HIGGSFIELD_MCP_SCENE_BUILDER_3D_GET_PROJECT` Read a 3D Jutsu project's current revision, scene sequence, active operation, and committed artifacts. Obtain `projectId` from `scene_builder_3d_list_projects`, `scene_builder_3d_create_project`, or an explicit user selection. An authorized project with `exists: false` is a valid empty scene at revision 0. Use `scene_builder_3d_query_python` to inspect actual objects, dimensions, materials, cameras, and lights before editing. If an operation is active, use `scene_builder_3d_get_operation` to settle it before another mutation. Scene edits use `scene_builder_3d_run_python` with the exact revision and scene sequence inspected; never guess these guards. Finish each completed scene creation, edit, or import task by calling `scene_builder_3d_show_scene` once as the final 3D Jutsu tool call before your final reply, after mutations have settled and verification is complete. Pass the same `projectId` and the exact committed `revision` of the final result: `revisionAfter` from the final successful mutation, or the settled `project.revision` after an import. Do not guess the revision. This shows the result to the user; a text summary or download link alone does not finish scene delivery. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `projectId` | string | Yes | Project ID from scene_builder_3d_list_projects, scene_builder_3d_create_project, or the user's explicit selection. Required on every project-scoped tool. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `ok` | boolean | Yes | | | `exists` | boolean | Yes | | | `project` | object | Yes | | | `projectUrl` | string | Yes | Open this project in 3D Jutsu. | ### Scene builder 3d import asset **Slug:** `HIGGSFIELD_MCP_SCENE_BUILDER_3D_IMPORT_ASSET` Import a confirmed catalog GLB from `scene_builder_3d_search_assets` into the selected project as a collaborative scene entity. Supply the catalog's asset ID, not a URL. The tool runtime resolves and uploads the bytes, reads the project guards, submits the import, and waits for it to appear in the settled scene. Do not import while another mutation is active. After import, inspect dimensions, placement, orientation, contact, and materials with `scene_builder_3d_query_python` before further edits. Do not repeat the whole import to poll: it can create a duplicate. If an import fails, report the error; never fall back to Python network calls or base64-encoded model bytes. Copy catalogSearch from the search result's importArguments. If settled is false, poll scene_builder_3d_get_project until appliedSceneSequence reaches targetSceneSequence. If submissionUnknown is true, inspect the returned entityId before deciding to retry. This version accepts catalog assets only. Finish each completed scene creation, edit, or import task by calling `scene_builder_3d_show_scene` once as the final 3D Jutsu tool call before your final reply, after mutations have settled and verification is complete. Pass the same `projectId` and the exact committed `revision` of the final result: `revisionAfter` from the final successful mutation, or the settled `project.revision` after an import. Do not guess the revision. This shows the result to the user; a text summary or download link alone does not finish scene delivery. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `name` | string | No | | | `assetId` | string | Yes | Confirmed catalog ID from scene_builder_3d_search_assets. Attachment IDs are not supported by this tool. | | `projectId` | string | Yes | Project ID from scene_builder_3d_list_projects, scene_builder_3d_create_project, or the user's explicit selection. Required on every project-scoped tool. | | `transform` | object | No | Editor/glTF coordinates: metres, Y up, XYZW quaternion. Blender bpy coordinates are Z up; account for that when comparing transforms. | | `operationId` | string | Yes | Stable ID for this logical operation. Reuse only for an identical request, including code and guards. | | `waitSeconds` | integer | No | Wait up to this many seconds; poll scene_builder_3d_get_operation if still active. | | `catalogSearch` | string | No | Copy catalogSearch from the search result's importArguments so the catalog ID can be resolved in the same result set. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `ok` | boolean | Yes | | | `name` | string | Yes | | | `error` | object | No | | | `source` | string | Yes | | | `assetId` | string | Yes | | | `settled` | boolean | No | Whether the accepted import has reached the committed scene. | | `entityId` | string | Yes | | | `nextTool` | string | No | | | `revision` | integer | No | | | `projectId` | string | Yes | | | `nextAction` | string | No | | | `projectUrl` | string | Yes | Open this project in 3D Jutsu. | | `operationId` | string | Yes | | | `sceneSequence` | integer | No | | | `submissionUnknown` | boolean | No | Inspect entityId before retrying: the import may already have been accepted. | | `targetSceneSequence` | integer | No | Poll until appliedSceneSequence reaches this value. | | `appliedSceneSequence` | integer | No | | ### Scene builder 3d list projects **Slug:** `HIGGSFIELD_MCP_SCENE_BUILDER_3D_LIST_PROJECTS` Discover the authenticated user's 3D Jutsu projects before choosing a scene to read or edit. Follow `nextCursor` to see more results. Use the selected project's `id` as `projectId` in every project-scoped 3D Jutsu tool; no call sets a global active project. Match the user's named project, and ask them to choose if the result is ambiguous. Then call `scene_builder_3d_get_project` for its current state. A project's presence here does not bypass permission checks on subsequent calls. To start a new project, use scene_builder_3d_create_project. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `limit` | integer | No | | | `cursor` | string | No | | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `ok` | boolean | Yes | | | `projects` | array | Yes | | | `nextCursor` | string | Yes | | ### Scene builder 3d query python **Slug:** `HIGGSFIELD_MCP_SCENE_BUILDER_3D_QUERY_PYTHON` Inspect the latest settled Blender scene without committing changes. `bpy` and the `artifacts` registry are available; assign concise JSON-serializable findings to `result`. Query exact names, metre-scale dimensions, transforms, parents, collections, materials, cameras, lights, visibility, and animation settings as needed. Inspect Blender RNA when an API or enum is uncertain. Temporary scene changes are discarded, including camera changes used for inspection. A query can render and publish images for visual inspection: allocate a target with `artifacts.file(name="preview.png", media_type="image/png")`, write the image to `target.path`, and call `target.publish()`. Resolve published IDs with `scene_builder_3d_get_artifact`. Use the successful query's `revisionBefore` and `sceneSequenceAfter` as the guards for the next `scene_builder_3d_run_python` call. If still active, poll `scene_builder_3d_get_operation`. Reuse an operation ID only to retry the identical request. Imported model bytes must enter through `scene_builder_3d_import_asset`; do not fetch URLs or embed file bytes in Python. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `code` | string | Yes | Use bpy and artifacts; assign JSON-serializable findings to result. Files persist only via artifacts.file(name=..., media_type=...), writing to target.path, then target.publish(). At most eight PNG/JPEG/MP4 files, 512 MiB each and 1 GiB total; images at most 16384 pixels per side and 64 MP. Invalid published files fail the operation. Set image_settings.media_type='IMAGE' before PNG/JPEG, or 'VIDEO' before FFMPEG with MPEG4/H264. No network fetches or embedded model bytes; use scene_builder_3d_import_asset. | | `projectId` | string | Yes | Project ID from scene_builder_3d_list_projects, scene_builder_3d_create_project, or the user's explicit selection. Required on every project-scoped tool. | | `operationId` | string | Yes | Stable ID for this logical operation. Reuse only for an identical request, including code and guards. | | `waitSeconds` | integer | No | Wait up to this many seconds; poll scene_builder_3d_get_operation if still active. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `ok` | boolean | Yes | | | `error` | object | No | | | `nextTool` | string | No | | | `terminal` | boolean | Yes | False while the operation still needs polling; true includes success and failure. | | `operation` | object | Yes | | | `projectUrl` | string | Yes | Open this project in 3D Jutsu. | | `nextArguments` | object | No | | ### Scene builder 3d run python **Slug:** `HIGGSFIELD_MCP_SCENE_BUILDER_3D_RUN_PYTHON` Commit one coherent Blender scene edit against the exact revision and scene sequence you inspected with `scene_builder_3d_get_project` or `scene_builder_3d_query_python`. `bpy` and `artifacts` are available; assign JSON-serializable findings to `result`. Keep one mutation active per project, including imports. If this operation remains active, poll `scene_builder_3d_get_operation` before editing again. Reuse `operationId` only for the identical code and preconditions. On a stale-state conflict, inspect the scene again and regenerate the edit with fresh guards and a new operation ID. A successful mutation advances `revisionAfter`. Build editable scenes at metre scale with descriptive object names and semantic parts. For a new multi-object scene, establish the delivery camera, a motivated key light, fill, and ambient light with the first blockout. Preserve existing scene intent when editing. Work through silhouette, measured proportions, depth, contact, camera framing, then detail; adjust lights with the geometry. Keep modifiers and material roles editable, account for parent transforms, and prefer shared mesh data over large loops of creation operators. Use portable Principled materials and existing embedded textures when GLB delivery matters; procedural shaders and world lighting do not reliably carry into GLB. Use Point, Sun, or Spot lights for portable lighting. Do not invent texture paths or fetch external files from Blender. This worker pins Blender 5.2. Use `BLENDER_EEVEE`, `BLENDER_WORKBENCH`, or `CYCLES`, not `BLENDER_EEVEE_NEXT`. Query RNA instead of assuming older APIs such as `use_bloom`, `use_auto_smooth`, or render tile settings exist. Code is capped at 256 KiB, and execution and checkpoint/export must fit the configured worker deadline. Keep renders small and samples low; split expensive work into coherent edits. Committed scenes are finalized with Eevee and Khronos PBR Neutral. For animation, establish fps, frame range, rest pose, and timing first; key only intended properties, choose interpolation deliberately, and inspect rest, peak, final pose, contacts, and loop seams. Avoid promising long video renders before validating cost. Successful execution does not establish visual correctness. Render from the delivery camera, publish the image through `artifacts`, then retrieve it with `scene_builder_3d_get_artifact` and inspect it using the client's image capability. Fix framing, floating/intersecting parts, missing textures, and lighting before claiming completion. Workbench does not test scene lights; use a small Eevee render for that. If visual inspection is unavailable, state what remains unverified. Use `scene_builder_3d_import_asset` for models and `scene_builder_3d_get_glb` or `scene_builder_3d_get_blend` when the user needs the committed files. Finish each completed scene creation, edit, or import task by calling `scene_builder_3d_show_scene` once as the final 3D Jutsu tool call before your final reply, after mutations have settled and verification is complete. Pass the same `projectId` and the exact committed `revision` of the final result: `revisionAfter` from the final successful mutation, or the settled `project.revision` after an import. Do not guess the revision. This shows the result to the user; a text summary or download link alone does not finish scene delivery. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `code` | string | Yes | Use bpy and artifacts; assign JSON-serializable findings to result. Files persist only via artifacts.file(name=..., media_type=...), writing to target.path, then target.publish(). At most eight PNG/JPEG/MP4 files, 512 MiB each and 1 GiB total; images at most 16384 pixels per side and 64 MP. Invalid published files fail the operation. Set image_settings.media_type='IMAGE' before PNG/JPEG, or 'VIDEO' before FFMPEG with MPEG4/H264. No network fetches or embedded model bytes; use scene_builder_3d_import_asset. | | `revision` | integer | Yes | Exact committed revision inspected; do not guess. | | `projectId` | string | Yes | Project ID from scene_builder_3d_list_projects, scene_builder_3d_create_project, or the user's explicit selection. Required on every project-scoped tool. | | `operationId` | string | Yes | Stable ID for this logical operation. Reuse only for an identical request, including code and guards. | | `waitSeconds` | integer | No | Wait up to this many seconds; poll scene_builder_3d_get_operation if still active. | | `expectedSceneSequence` | integer | Yes | Exact settled scene sequence inspected by your query. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `ok` | boolean | Yes | | | `error` | object | No | | | `nextTool` | string | No | | | `terminal` | boolean | Yes | False while the operation still needs polling; true includes success and failure. | | `operation` | object | Yes | | | `projectUrl` | string | Yes | Open this project in 3D Jutsu. | | `nextArguments` | object | No | | ### Scene builder 3d search assets **Slug:** `HIGGSFIELD_MCP_SCENE_BUILDER_3D_SEARCH_ASSETS` Search the curated GLB model catalog available to 3D Jutsu. This read is authorized against `projectId`; the catalog itself is shared. Pass a returned `assetId` to `scene_builder_3d_import_asset` for the same selected project. Search results are available models, not objects already present in the scene. Inspect existing scene objects with `scene_builder_3d_query_python` before deciding what to add. Never invent an asset ID or turn a catalog URL into Python download code. Copy the returned importArguments, including catalogSearch, into scene_builder_3d_import_asset. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `limit` | integer | No | | | `search` | string | No | | | `projectId` | string | Yes | Project ID from scene_builder_3d_list_projects, scene_builder_3d_create_project, or the user's explicit selection. Required on every project-scoped tool. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `ok` | boolean | Yes | | | `total` | integer | Yes | | | `assets` | array | Yes | | | `projectUrl` | string | Yes | Open this project in 3D Jutsu. | ### Scene builder 3d show scene **Slug:** `HIGGSFIELD_MCP_SCENE_BUILDER_3D_SHOW_SCENE` Show a minimal interactive 3D Jutsu scene preview with orbit, pan, zoom, a basic animation timeline with play/pause and seeking, and a link to the website. Choose projectId with scene_builder_3d_list_projects, scene_builder_3d_create_project, or the user's explicit selection. Pass revisionAfter from a successful edit to show that exact result, or omit revision for the latest committed GLB. Wait for edits to settle with scene_builder_3d_get_operation before showing their result. This reads an existing export; it never starts Blender, edits the scene, or includes uncommitted collaborative changes. Call this when the user asks to see the scene. For a completed scene creation, edit, or import task, call it once as the final 3D Jutsu tool call before your final reply, after settlement and verification. The widget is for the user to inspect; it does not give the agent visual evidence. Use scene_builder_3d_query_python and scene_builder_3d_get_artifact for the agent's visual verification. If the client cannot display widgets, provide the returned projectUrl. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `revision` | integer | No | Committed revision to preview. Omit for the latest committed revision; use revisionAfter to show the exact result of an edit. | | `projectId` | string | Yes | Project ID from scene_builder_3d_list_projects, scene_builder_3d_create_project, or the user's explicit selection. Required on every project-scoped tool. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `ok` | boolean | Yes | | | `kind` | string | Yes | | | `artifact` | object | Yes | | | `download` | object | Yes | | | `revision` | integer | Yes | | | `projectId` | string | Yes | | | `projectUrl` | string | Yes | Open this project in 3D Jutsu. | ### Select workspace **Slug:** `HIGGSFIELD_MCP_SELECT_WORKSPACE` Set or clear the active workspace — the one all subsequent MCP operations bill against and read from (generations, balance, transactions, uploads, custom references). How to work with workspaces: (1) call `list_workspaces` first to see the user's workspaces with their `id`, plan, available credits, and which one is currently active (`is_selected`); (2) call `select_workspace` with the chosen `workspace_id` to switch — e.g. to run and bill work under a shared/team workspace instead of the private default; (3) call again with `clear: true` to return to the default private workspace. The selection persists across sessions and clients until changed or cleared, so it stays in effect for later turns without re-selecting. When the user belongs to more than one workspace, confirm which one to use before billable operations. Returns an error if the workspace doesn't exist or the user isn't a member. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `clear` | boolean | No | When true, clear the selected workspace instead of selecting one. | | `workspace_id` | string | No | Workspace UUID from `list_workspaces`. Required unless `clear` is true. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `success` | boolean | No | | | `workspace` | object | No | | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | ### Shorts studio create **Slug:** `HIGGSFIELD_MCP_SHORTS_STUDIO_CREATE` Start a Shorts Studio short: restyle one uploaded source video (4s–120s) into a set of AI-generated short-form clips using a style preset. PAID — reserves credits. Prerequisites, gathered in whatever order fits the conversation: (1) a style preset — pick one via shorts_studio_list_presets or make one with shorts_studio_create_preset; (2) a source video — an uploaded video_input id from media_upload_widget (type=video). If the user hasn't provided a source video yet, ask them to upload one before calling this. Output orientation defaults to 9:16 (vertical); pass aspect_ratio:'16:9' for horizontal. Returns a session with empty job_ids; poll shorts_studio_status until clips appear. Set get_cost=true with duration_seconds to estimate the credit cost without submitting a job — no preset or source video needed for the estimate. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `get_cost` | boolean | No | If true, return the credit cost for a short of duration_seconds without submitting a job. | | `preset_id` | string | No | Style preset id from shorts_studio_list_presets or shorts_studio_create_preset. Required unless get_cost is true. | | `resolution` | string | No | Only 720p is supported. | | `aspect_ratio` | string ("9:16" | "16:9") | No | Output orientation. Defaults to 9:16 (vertical); use 16:9 for horizontal. | | `preset_source` | string ("cms" | "user") | No | Preset library: 'user' or 'cms' (the item's preset_source). Required unless get_cost is true. | | `source_video_id` | string | No | Uploaded source video's video_input id (from media_upload_widget, type=video). Required unless get_cost is true. | | `duration_seconds` | number | No | Source video duration in seconds. Required when get_cost is true. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `id` | string | No | | | `cost` | object | No | Populated only when called with get_cost: true. No job was submitted. | | `status` | string ("queued" | "in_progress" | "completed") | No | | | `job_ids` | array | No | | | `resolution` | string | No | | | `source_video_id` | string | No | | ### Shorts studio create preset **Slug:** `HIGGSFIELD_MCP_SHORTS_STUDIO_CREATE_PRESET` Create a user-owned Shorts Studio style preset from reference media (videos + images). This just stores a STYLE — no generation, no credits. Reference media must be public https URLs (use an uploaded media's url or media_import_url first). Limits: ≤10 media total, each video's duration ≤30s (send `duration` so the cap applies). Returns the id and preset_source to feed into shorts_studio_create. If the user did not give a name, invent a random friendly two-word name yourself (e.g. 'Amber Drift', 'Neon Tide', 'Velvet Dusk') — never leave it blank or ask. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `name` | string | Yes | Preset name. If the user didn't provide one, generate a random friendly two-word name (e.g. 'Amber Drift', 'Neon Tide') rather than asking or leaving it empty. | | `prompt` | string | No | Optional style direction (e.g. 'cinematic teal & orange'). | | `thumbnail` | string | No | Optional thumbnail URL. | | `image_medias` | array | No | Style-reference images. | | `video_medias` | array | No | Style-reference videos. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `id` | string | Yes | | | `name` | string | Yes | | | `preset_source` | string | Yes | | ### Shorts studio list presets **Slug:** `HIGGSFIELD_MCP_SHORTS_STUDIO_LIST_PRESETS` Browse Shorts Studio style presets — the visual STYLE a short is restyled toward. Use this when the user wants to make a short and needs to choose a look: they can pick one of these or create their own style with shorts_studio_create_preset. Returns the user's own presets first, then the CMS library; each item carries a `preset_source` to pass straight into shorts_studio_create. Paginated: if next_cursor is not null, pass it as cursor to get the next page. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `cursor` | string | No | Pass next_cursor from a previous response to get the next page. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `items` | array | Yes | | | `has_more` | boolean | Yes | | | `next_cursor` | string | Yes | | | `can_create_preset` | boolean | Yes | | ### Shorts studio list sessions **Slug:** `HIGGSFIELD_MCP_SHORTS_STUDIO_LIST_SESSIONS` List the caller's past Shorts Studio sessions (newest first) to find a session_id to poll with shorts_studio_status. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `size` | integer | No | Page size (default 20). | | `cursor` | number | No | created_at cursor from a prior response. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `items` | array | Yes | | | `cursor` | string | Yes | | | `has_more` | boolean | Yes | | ### Shorts studio status **Slug:** `HIGGSFIELD_MCP_SHORTS_STUDIO_STATUS` Poll one Shorts Studio session. Returns {id, status, job_ids}. status='completed' means every clip job is terminal (not necessarily successful). Poll each job_id via job_status for its clip video url and per-clip status. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `session_id` | string | Yes | Session id from shorts_studio_create or shorts_studio_list_sessions. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `id` | string | Yes | | | `status` | string ("queued" | "in_progress" | "completed") | Yes | | | `job_ids` | array | Yes | | | `resolution` | string | Yes | | | `source_video_id` | string | Yes | | ### Show characters **Slug:** `HIGGSFIELD_MCP_SHOW_CHARACTERS` Soul Characters widget — reusable trained identity models. Actions: `list` (browse), `train` (needs `name` + 5-20 ref images, ~10 min, non-blocking — widget polls), `status` (inspect by `soul_id`). Presence of `name`/`images`/`medias` ⇒ train mode. Call `train` only on explicit ask for a reusable Soul / digital twin / identity, or when 5+ ref photos are supplied. Ref images accept: media_id UUIDs from media_confirm, completed image-job IDs, or https URLs. Never local paths — upload via media_upload → PUT bytes → media_confirm first. CONSTRAINTS: - Trained Soul is usable ONLY with `soul_2` (Soul V2) and `soul_cinematic` (Soul Cinema). For any other model, the user needs `show_reference_elements`. - ONE soul_id per generation. Multi-character shots ('me + friend', 'two people') must use `show_reference_elements` (supports multiple `<<<UUID>>>` placeholders). AMBIGUITY GUARD — character/avatar/digital-twin/'use my face' requests without a chosen path: do NOT call this tool yet; ask the user to pick: 1. Train Soul (this tool) — identity-faithful, ONE person, 5-20 photos, ~10 min, Soul V2 / Cinema only. 2. Save as Element (`show_reference_elements` action=create) — instant, single image, multiple subjects allowed, works with Nano Banana Pro / 2, GPT Image 2, Seedream 4.5 / 5 lite, Cinema Studio Image 2.5, Cinema Studio Video 2 / 3.0, Seedance 2.0, Kling 3.0. → Soul signals: 'train' / 'digital twin' / 'identity' / 5+ photos of same person. → Force Elements: >1 character in shot, non-person subject, single image, mention of a non-Soul model, instant result wanted. After ready: `generate_image` with `model: 'soul_2'` (or `soul_cinematic`) + the returned `soul_id`. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `name` | string | No | Character name, required for action=train. | | `size` | integer | No | Number of characters per page. | | `type` | string ("soul" | "soul_2" | "soul_cinematic") | No | Character type. Use soul_2 for model='soul_2'; use soul_cinematic for model='soul_cinematic'; use soul for legacy Soul references. | | `action` | string | No | Mode selector: list, train/create, or status/get. | | `cursor` | number | No | Pagination cursor from previous response's next_cursor. | | `images` | array | No | For Soul training: returned media_id UUIDs from media_confirm, completed image generation job IDs, or https image URLs. Required with medias to total 5-20 images for action=train. Do not pass local file paths. | | `medias` | array | No | Chat media references to resolve as training images for action=train. Values may be media_id UUIDs, completed image generation job IDs, or https image URLs. | | `status` | string ("ready" | "training" | "failed") | No | List filter. Use ready to find characters available for generation. | | `soul_id` | string | No | Character id for action=status. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `note` | string | No | | | `error` | string | No | | | `items` | array | No | | | `trained` | boolean | No | True when a new training job was started. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `next_cursor` | string | No | | | `training_id` | string | No | ID of the character that just started training; used by the widget for the live progress pill. | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | | `character_id` | string | No | ID of the character returned by status/get. | ### Show generation by ids **Slug:** `HIGGSFIELD_MCP_SHOW_GENERATION_BY_IDS` Render exactly 1-60 requested generation jobs in the full-profile gallery widget, ordered by index and paginated locally in groups of 12. Use once every jobs_wait group is terminal for generate_image_batch, generate_video_batch, or generate_audio_batch. Pass the complete indexed set collected from the batch tools. This tool fetches only those job IDs in bounded groups: it never loads generation history, uses cursors, requests additional pages, or adds other jobs. Do not use show_generations or job_display to present a completed batch. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `jobs` | array | Yes | Exact full-profile generation jobs to display. Results are ordered by index and paginated locally. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `jobs` | array | Yes | | | `items` | array | Yes | | | `all_found` | boolean | Yes | True when every requested job ID was fetched. Failed generations still count as found. | ### Show generations **Slug:** `HIGGSFIELD_MCP_SHOW_GENERATIONS` Browse completed non-Marketing Studio generation history and render one paginated page in the gallery widget. Returns generations with {id, type, status, model, params, results}. Use only when the user explicitly asks to browse regular generation history. Do not use this history tool after generate_*_batch or jobs_wait; show an exact completed batch with one show_generation_by_ids call instead. Use show_marketing_studio_generations for Marketing Studio video/image/ad history. Pass a prior generation's id as value in the medias array of a new generation to reuse it. Use job_display only to inspect one specific previous result. Paginated: if next_cursor is not null, pass it as cursor to get the next page. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `size` | string | No | Number of results per page | | `type` | string ("image" | "video" | "audio" | "3d") | No | Filter by media type | | `cursor` | string | No | Pass next_cursor from previous response to get next page | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | Error message if the list could not be fetched. | | `items` | array | No | Array of generations. Absent on error. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `next_cursor` | string | No | Pass as cursor to get next page. Null if no more results. | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | ### Show marketing studio generations **Slug:** `HIGGSFIELD_MCP_SHOW_MARKETING_STUDIO_GENERATIONS` Browse past completed Marketing Studio generations only. Returns Marketing Studio video and ad/image generations with {id, type, status, model, params, results}. Use show_generations for non-Marketing Studio image/video history. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `size` | integer | No | Number of results per page | | `cursor` | number | No | Pass next_cursor from previous response to get the next page | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | Error message if the list could not be fetched. | | `items` | array | No | Array of Marketing Studio generations. Absent on error. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `next_cursor` | string | No | Pass as cursor to get next page. Null if no more results. | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | ### Show marketing studio v2 **Slug:** `HIGGSFIELD_MCP_SHOW_MARKETING_STUDIO_V2` Open Marketing Studio — a template gallery widget with category tabs (UGC ads, product shots, motion graphics, posters, ads, marketplace) and a preset grid the user browses and recreates from with their own product image. Use this whenever the user asks for Marketing Studio or wants marketing assets from a template/preset catalog. The widget handles preset selection, inputs, generation, and result display itself — no follow-up tool calls needed. If the result is a workspace-selection error, ask the user which workspace to use, call select_workspace, then call this tool again. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `category` | string ("all" | "ugc" | "product-shot" | "motion" | "ads" | "posters" | "marketplace") | No | Category tab to open on. Defaults to 'all'. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `presets` | object | No | | | `category` | string | No | | | `categories` | array | No | | | `request_id` | string | No | | ### Show medias **Slug:** `HIGGSFIELD_MCP_SHOW_MEDIAS` List your uploaded media files by type. Returns media IDs, URLs, and creation timestamps. Call once with the single type the user asked for (default image); do not enumerate the other types unless the user explicitly asks for them. Pass media IDs as value in the medias array of generation tools. Paginated: if next_cursor is not null, pass it as cursor to get the next page. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `size` | integer | No | Number of results per page | | `type` | string ("image" | "video" | "audio") | No | Media type to list. Defaults to image. | | `cursor` | number | No | Pass next_cursor from previous response to get next page | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `items` | array | No | Array of uploaded media files. Absent on error. | | `media_type` | string ("image" | "video" | "audio") | No | The media type this listing is for (echoes the request's type). | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `next_cursor` | string | No | Pass as cursor to get next page. Null if no more results. | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | ### Show plans and credits **Slug:** `HIGGSFIELD_MCP_SHOW_PLANS_AND_CREDITS` Open the single combined pricing widget for everything billing-related. The widget has two tabs the user can switch between: **Upgrade Plan** (Plus + Ultra, monthly + annual subscription cards) and **Top-up Credits** (one-time credit packs of 500 / 1,000 / 2,000 / 4,000 credits). Cards include feature lists, 7-Day Unlimited highlights, and 365-Day Unlimited blocks pulled from the live pricing config. Each plan card and credit pack has a CTA that links directly to the relevant Stripe or Higgsfield checkout/setup URL — no separate tool is needed to mint checkouts. For every billing request, the text response and `assistant_response` are intentionally short, user-facing sales copy with checkout URLs wrapped as action-specific Markdown links such as `[Go to Checkout](url)`, `[Higgsfield Upgrade](url)`, `[Higgsfield Credit Top-up](url)`, `[Higgsfield Auto-refill](url)`, `[Higgsfield Team Top-up](url)`, or `[Higgsfield Team Auto-refill](url)`; relay that response verbatim instead of summarizing, saying only that the widget opened, or listing options without links. If the user asks to buy credits or they are out of credits, first push auto-refill when `auto_refill_purchase_link` is present, then show `credit_purchase_links`. If the user asks to upgrade or a minimum plan is required, show `plan_purchase_links`. Pass `intent='auto_refill'` for out-of-credits recovery, `intent='topup'` for one-time credit packs, `intent='upgrade'` for plan upgrades, or `intent='trial'` when the user specifically asks for the free trial so the response is ordered for that purchase path. FREE TRIAL: when `free_trial` is present in the response, the user is eligible for a 3-day $0 Plus trial with MCP-only credits — the widget shows it and the text response leads with it. In text-only clients ALWAYS relay `free_trial.compliance_note` verbatim (MCP-only, card required, automatic charge after the trial unless cancelled, how to cancel by saying 'cancel auto-renewal'). When `free_trial` is absent, NEVER speculate about trial eligibility or mention fraud/abuse checks — present the paid plans neutrally. When `initial_view='trial_upgrade'`, the user's trial credits are exhausted: relay the numbered upgrade options plus the renewal reminder, and mention that saying 'cancel auto-renewal' stops the upcoming charge while keeping trial access. To cancel the trial's auto-renewal, call `cancel_trial_auto_renewal` instead of this tool. Use this tool for ANY of these requests: plans, pricing, subscriptions, upgrade options, comparing tiers, buying credits, topping up credits, refilling credits, credit packs. Do not look for separate `show_plans` or `show_credit_topups` tools — both have been merged into this one. Returns `already_subscribed: true` when the workspace is already on a paid plan; the widget hides the Upgrade tab in that case and shows only credit top-ups. Team-plan workspaces: `workspace_kind` field indicates the context. When `workspace_kind='team_owner'`, the widget renders team-specific Top-up and Auto-refill UIs and emits `team_purchase_links` (two links: `team_top_up` and `team_auto_refill`) that deeplink to the team billing modals on higgsfield.ai — relay both Markdown links in the text response. When `workspace_kind='team_member'`, no purchase links are returned; the widget shows a read-only notice and the text response tells the user only the workspace owner can buy credits or change auto-refill. Do not invent purchase links for members. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `intent` | string ("upgrade" | "topup" | "auto_refill" | "trial" | "general") | No | Purchase path to prioritize in the widget and text fallback. Use auto_refill for out-of-credits recovery, topup for one-time credit packs, upgrade for minimum-plan errors or plan changes, trial when the user specifically asks for the free trial, and general for pricing comparison. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `plans` | array | No | Subscription plan cards with rich pricing-config data merged in. Empty when the user is on a paid plan. | | `topups` | array | No | One-time credit top-up packages. Empty when the user is on the free plan. | | `free_trial` | object | No | Free trial offer (see `kind` for what it starts). Present ⇔ the user is eligible. When absent, do NOT speculate about why — keep copy neutral (never mention eligibility, fraud, or abuse checks). | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. | | `team_owner` | object | No | Team-owner config: credit price, deeplink URLs, quick-select chips, auto-refill field limits, workspace name. Only present when workspace_kind=team_owner. | | `auto_refill` | string | No | Credits auto-refill settings. Drives the auto-refill subtab inside the top-up panel; only shown when is_eligible=true. | | `initial_tab` | string ("upgrade" | "topup") | No | Tab the widget should select first for this tool invocation. | | `team_member` | object | No | Team-member context: read-only workspace metadata. Only present when workspace_kind=team_member. | | `checkout_url` | string | No | Direct URL for the primary checkout/setup action. Agents MUST show this exact link in text-only clients. | | `current_plan` | string | No | Plan type the workspace is currently on, when already_subscribed=true. | | `initial_view` | string ("plans" | "trial" | "trial_upgrade") | No | Layout the widget opens with: plans (Plus/Ultra grid, plus the trial section when free_trial is present), trial (standalone trial card), trial_upgrade (trial credits exhausted — upgrade view). | | `trial_status` | object | No | Current MCP free-trial state, when the status endpoint responded. | | `checkout_label` | string | No | CTA label for checkout_url. | | `purchase_links` | array | No | Flattened direct purchase/setup links. Agents MUST relay relevant URLs when the client does not render the billing widget. | | `sales_headline` | string | No | Personalized seller-style headline that explains the recommended purchase path. | | `workspace_kind` | string ("individual" | "team_owner" | "team_member") | No | Workspace context: individual private workspace, team-plan workspace owner, or team-plan member. Drives both widget UI and which links are returned. | | `plan_comparison` | object | No | STATIC Free/Plus/Ultra comparison table for the trial-exhausted view. | | `primary_cta_text` | string | No | Action-oriented CTA label for the primary purchase link. | | `promotional_text` | string | No | Short promoter-style copy suitable for text-only MCP clients. | | `topup_expire_days` | number | No | Number of days extra credits remain valid after purchase. | | `already_subscribed` | boolean | No | True if the workspace already has a paid plan. | | `assistant_response` | string | No | Ready-to-send promoter-style purchase response with checkout URLs formatted as action-specific Markdown links, e.g. [Go to Checkout](url), [Higgsfield Upgrade](url), [Higgsfield Credit Top-up](url), or [Higgsfield Auto-refill](url). Agents should relay this in text-only clients or when the widget location is unclear. | | `plan_purchase_links` | array | No | Direct subscription upgrade checkout links. | | `team_purchase_links` | array | No | Team-plan owner deeplinks (top-up + auto-refill). Only present when workspace_kind=team_owner. | | `trial_purchase_link` | object | No | Direct $0 trial checkout link, when the user is eligible. | | `auto_top_up_setup_url` | string | No | Checkout/setup URL for credits auto-refill. Render the setup banner only when this URL is present. | | `credit_purchase_links` | array | No | Direct one-time credit-pack checkout links. | | `primary_purchase_link` | object | No | Best single checkout/setup link for the requested intent. For credit recovery this prioritizes auto-refill when eligible, then one-time top-ups. | | `recommendation_reason` | string | No | Short rationale for why this offer is being shown for the user's current plan/eligibility. | | `auto_refill_purchase_link` | object | No | Direct auto-refill setup link, when available. | | `unlim_trial_in_mcp_active` | boolean | No | Presentation-only gate derived from the trial `kind` (offer or existing trial). False/absent keeps every legacy widget branch. | | `top_annual_discount_percent` | string | No | Largest annual discount percentage to show near the annual billing toggle. | ### Show reference elements **Slug:** `HIGGSFIELD_MCP_SHOW_REFERENCE_ELEMENTS` Elements widget — reusable characters / environments / props per workspace. Actions: - `list` (default; paginated by `created_at` DESC, use `cursor` from prev `next_cursor`). - `get` (default when `element_id` is set). - `create`: pass `medias[]` as `{ id, url, type: 'media_input' | 'image_job' }`. Upload first via media_upload → PUT bytes → media_confirm. `category='auto'` lets the server classify (use explicit only on user ask). Omit `name` to auto-derive (per-workspace unique, collisions get a numeric suffix). Returns synchronously. AMBIGUITY GUARD vs Soul — user wants a reusable face of one specific person (digital twin / 'my avatar' / identity) without a chosen path: do NOT silently create; ask: 1. Element (this tool action=create) — instant, single image, MULTIPLE references per generation, works with Nano Banana Pro / 2, GPT Image 2, Seedream 4.5 / 5 lite, Cinema Studio Image 2.5, Cinema Studio Video 2 / 3.0, Seedance 2.0, Kling 3.0. NOT for Soul V2 / Cinema. 2. Soul (`show_characters` action=train) — 5-20 photos, ~10 min, ONE person, Soul V2 / Cinema only. Skip the question → Elements on: >1 character/subject in one shot (Soul can't), non-person subject, single image, mention of Nano Banana / Seedream / Kling / Cinema Studio, instant result. Skip → Soul on: 'train' / 'digital twin' / 'identity', or 5+ photos of one person for solo outputs. USAGE IN GENERATION (internal — never explain to user): Embed `<<<element_id>>>` inside `params.prompt` of `generate_image` / `generate_video`. Backend auto-injects the image and rewrites to `@element_name`. Multiple placeholders per prompt OK. Example: `"Cinematic portrait of <<<UUID>>> on a rooftop"`, `"<<<A>>> handing coffee to <<<B>>> in a Paris cafe"`. SUPPORTED MODELS (`params.model` = machine name, friendly in parens): - Image: `nano_banana_pro` (Nano Banana Pro), `nano_banana_2` (Nano Banana 2), `gpt_image_2` (GPT Image 2), `seedream_v4_5` (Seedream 4.5), `seedream_v5_lite` (Seedream 5.0 lite), `cinematic_studio_2_5` (Cinema Studio Image 2.5). - Video: `cinematic_studio_video_v2` (Cinema Studio Video 2), `cinematic_studio_3_0` (Cinema Studio Video 3.0), `seedance_2_0` (Seedance 2.0), `kling3_0` (Kling 3.0 — REQUIRES a `start_image` in `params.medias`; element placeholder alone won't trigger reference usage). Map friendly→machine silently. Other models silently ignore the placeholder. USER-FACING STYLE: use friendly model names only; never expose machine names, `<<<UUID>>>` syntax, `params.model` / `params.prompt`, `generate_image` / `generate_video`, or 'job_set_type'. Reference elements by `name`, never id. GUARDS: - `@name` form does NOT work in tool calls — only `<<<UUID>>>` in `params.prompt`. - Do NOT put element ids in `params.medias` / `params.input_images` — placeholder handles injection. - `kling3_0` only honors reference elements when an explicit `start_image` is provided in `params.medias`. If the user wants Kling 3.0 with an element but hasn't supplied a start frame, ask for one (upload via media_upload → PUT bytes → media_confirm, or pick a prior generation) before calling `generate_video`. Without a start_image, pick another video model from the list. - Only `status: completed` elements are usable; skip `processing` / `ip_checking` / `failed` / `kling_failed` / `nsfw`. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `name` | string | No | [action=create] Element name, max 32 chars. Spaces are normalised to '-'. If omitted, the server derives a name from the media. | | `size` | integer | No | [action=list] Number of elements per page (1-100). | | `action` | string ("list" | "get" | "create") | No | Operation mode. Defaults to `get` if `element_id` is set, otherwise `list`. | | `cursor` | number | No | [action=list] Pass `next_cursor` from a previous response to get the next page. | | `medias` | array | No | [action=create] Image references. Required. URLs must be https (private/loopback hosts rejected); normally Higgsfield upload URLs returned by media_upload → PUT bytes → media_confirm. | | `category` | string ("auto" | "character" | "environment" | "prop") | No | [action=create] `auto` lets the server classify from the first images. Use a specific category only if the user is explicit. Defaults to `auto`. | | `element_id` | string | No | [action=get] Fetch a single reference element by id. | | `description` | string | No | [action=create] Optional free-form description, stored as-is. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `items` | array | No | Reference elements. Single-element when `action=get`, otherwise the page from `action=list`. | | `element` | object | No | [action=create] The created reference element. | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `next_cursor` | string | No | [action=list] Pass as `cursor` to fetch the next page. Null when no more pages. | | `upgrade_url` | string | No | Upgrade URL. If present, you MUST show this exact upgrade link to the user so they can upgrade to continue working. | ### Sync agents **Slug:** `HIGGSFIELD_MCP_SYNC_AGENTS` Sync Agents — imports the user's user-authored Skills and a personality dump from the current host LLM into Higgsfield. One trigger, one upload, one final confirmation. Calling modes: 1. `message: "/sync-agents"` — server returns a short ack in `content[0].text` plus an assistant-only directive containing a self-contained Python upload script (pre-wired with a one-time presigned POST URL scoped to one per-user prefix). Print the ack verbatim. Then follow the directive: enumerate user-authored skills + synthesize `personality.md` into `/tmp/profile-import/{skills,personality}/`, run the script in your code-execution sandbox, capture its single-line JSON summary, and call this tool again with that summary as `message`. 2. `message: "<script summary JSON>"` — server reads the uploaded .md files, parses each, and upserts the user's Skill rows. Returns a one-line confirmation summarising counts (e.g. "Imported 3 skill(s) (2 new, 1 updated) · personality queued for save to your memory."). Print that confirmation verbatim to the user. **Also pass `host`** on this call — your own runtime identifier (e.g. `claude_ai`, `claude_code`, `codex`, `cursor`); it is stamped on every newly imported skill's `import_origin` so the marketplace can attribute origin per host. No polling, no chains. Each call returns synchronously. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `host` | string ("claude_ai" | "claude_code" | "codex" | "cursor" | "windsurf" | "hermes" | "openclaw" | "other") | Yes | Identifier of the host LLM/runtime you are running inside. Stamped on each imported skill's `import_origin` column so the marketplace can attribute imports per host. Self-classify honestly: `claude_ai` (Claude.ai web/desktop), `claude_code` (Claude Code CLI), `codex` (OpenAI Codex / ChatGPT code interpreter), `cursor`, `windsurf`, `hermes` (Higgsfield hermes-agent), `openclaw` (Higgsfield OpenClaw), or `other` if none fit. Do not invent values — the enum is closed; pick `other` when uncertain. | | `message` | string | Yes | Either the literal trigger `/sync-agents` (server replies with an assistant-only Python upload script wired to a per-user S3 presigned-POST session — print only the short ack to the user, then run the script), or the JSON summary the script prints when it finishes (server finalises the import by parsing every uploaded .md into the user's Skill catalog). | ### Tiktok accounts **Slug:** `HIGGSFIELD_MCP_TIKTOK_ACCOUNTS` List the user's connected TikTok accounts. Returns each account's connector_id (needed by other tiktok_* tools) and status. `active` accounts are ready; `error` accounts need tiktok_reconnect; no accounts ⇒ offer tiktok_connect. Read-only. #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `accounts` | array | No | | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | ### Tiktok connect **Slug:** `HIGGSFIELD_MCP_TIKTOK_CONNECT` Start connecting the user's TikTok account. Returns an authorize_url — show it to the user as a link; they open it in a browser, approve access on TikTok, and land on a confirmation page. Afterwards call tiktok_accounts to verify the account became `active`. The URL expires in ~10 minutes. If an account already exists in `error` status, use tiktok_reconnect instead. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `name` | string | No | Only when connecting a SECOND account: a distinct label, e.g. "tiktok-brand". Default "tiktok". | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `expires_at` | string | No | The authorize URL is valid until this time (~10 minutes). | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `connector_id` | string | No | | | `authorize_url` | string | No | Show this URL to the user as a clickable link. | ### Tiktok music trending **Slug:** `HIGGSFIELD_MCP_TIKTOK_MUSIC_TRENDING` List trending commercially licensed tracks from TikTok's Commercial Music Library for the connected account. Show the user a few tracks with their listen links and let them pick; then pass the chosen track's id as music_sound_id to tiktok_publish. Music works for DIRECT_POST only (TikTok drafts don't keep it). There is no keyword search — offer genre/country/date_range filters instead. Read-only. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `genre` | string | No | TikTok CML genre enum, e.g. ALL, POP, HIP_HOP/RAP, LO-FI, EDM, COUNTRY, K-POP, CHILL_BEATS, EPIC. Default ALL. | | `limit` | integer | No | Tracks per page. Default 10. | | `offset` | integer | No | Page start. Default 0. | | `date_range` | string ("1DAY" | "7DAY" | "30DAY" | "90DAY") | No | Popularity window. Default 7DAY. | | `connector_id` | string | Yes | Active TikTok account from tiktok_accounts. | | `country_code` | string | No | Region whose trending chart to use, e.g. US. Default US. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `genre` | string | No | | | `limit` | number | No | | | `total` | number | No | | | `offset` | number | No | | | `tracks` | array | No | ALL fetched tracks (≤100) so the widget paginates locally; the text block lists only the current page. | | `date_range` | string | No | | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `connector_id` | string | No | Echoed for the widget's pagination calls. | | `country_code` | string | No | | ### Tiktok music tune **Slug:** `HIGGSFIELD_MCP_TIKTOK_MUSIC_TUNE` Open the tuning editor for one Commercial Music Library track the user already picked (via tiktok_music_trending): trim start/end and set track/original volumes. Pass the same genre/country_code/date_range filters that were used when the track was found, or the lookup may miss. The user copies the final configuration from the editor and pastes it into the chat; pass those values to tiktok_publish. Read-only. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `genre` | string | No | Same filter the track was found with, if any. | | `date_range` | string ("1DAY" | "7DAY" | "30DAY" | "90DAY") | No | | | `connector_id` | string | Yes | Active TikTok account from tiktok_accounts. | | `country_code` | string | No | | | `music_sound_id` | string | Yes | The picked track's id (from tiktok_music_trending / the user's paste). | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `error` | string | No | | | `track` | object | No | | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | ### Tiktok prepare publish **Slug:** `HIGGSFIELD_MCP_TIKTOK_PREPARE_PUBLISH` Step 1 of publishing to TikTok. Validates the media and TikTok account, creates a publish session, and returns what the user must review and choose (preview, privacy options, required declarations, confirmations). The media URL must be a Higgsfield-hosted asset (TikTok requires a verified source domain). Then collect the user's choices and call tiktok_publish. mode=DIRECT_POST posts to the profile; mode=UPLOAD_TO_DRAFT saves to the user's TikTok drafts. MEDIA LIMITS — check before calling, and convert or downscale locally if a file does not comply; a rejected file costs a full convert-and-re-upload round trip, and TikTok rejects some files only asynchronously, after the post was submitted. Photos: JPEG or WebP only (PNG is rejected by TikTok, and Higgsfield image generation emits PNG — convert first), each at most 20 MB, resolution must fit within 1920x1080 or 1080x1920, up to 35 images. Videos: MP4, WebM or MOV, at most 1 GB, 3-600 seconds, at least 360 px on both sides, 23-60 FPS. #### Input Parameters | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `mode` | string ("DIRECT_POST" | "UPLOAD_TO_DRAFT") | Yes | | | `title` | string | No | Caption / title. | | `is_aigc` | boolean | No | Prefill — only if the user already stated whether the media is AI-generated. | | `video_url` | string | No | Required for VIDEO. Must be a Higgsfield-hosted asset URL. | | `allow_duet` | boolean | No | Prefill — only if the user already stated it. | | `media_type` | string ("VIDEO" | "PHOTO") | Yes | | | `description` | string | No | | | `allow_stitch` | boolean | No | Prefill — only if the user already stated it. | | `connector_id` | string | Yes | Active TikTok account from tiktok_accounts. | | `photo_images` | array | No | Required for PHOTO. Higgsfield-hosted image URLs. | | `allow_comment` | boolean | No | Prefill — only if the user already stated it. | | `privacy_level` | string ("PUBLIC_TO_EVERYONE" | "MUTUAL_FOLLOW_FRIENDS" | "FOLLOWER_OF_CREATOR" | "SELF_ONLY") | No | Prefill for the publish form — pass ONLY if the user already stated it explicitly. | | `photo_cover_index` | integer | No | | | `commercial_content_disclosure` | object | No | Prefill — only if the user already stated it. | #### Output | Parameter | Type | Required | Description | |-----------|------|----------|-------------| | `mode` | string | No | | | `error` | string | No | | | `prefill` | object | No | Choices the user already made in chat; the publish form starts from these. | | `preview` | string | No | | | `media_type` | string | No | | | `request_id` | string | No | MCP server HTTP request ID for support/debugging. If present, show it to the user. | | `connector_id` | string | No | Echoed for the publish-form widget's server calls. | | `declarations` | object | No | | | `instructions` | string | No | | | `publish_session_id` | string | No | | | `interaction_settings` | string | No | | | `privacy_level_options` | string | No | | | `required_user_choices` | array | No | | | `required_confirmations` | array | No | | | `publish_session_expires_at` | string | No | | ### Tiktok publish **Slug:** `HIGGSFIELD_MCP_TIKTOK_PUBLISH` Step 2 of publishing. Call only after tiktok_prepare_publish and after collecting the user's explicit choices and confirmations. Pass the publish_session_id from prepare (the media is locked to it — do not resend URLs). Set every flag listed in the prepare response's required_confirmations to true; these represent real user consent (AIGC/branded-content/music/privacy). Optionally attach a commercial track via music_sound_id from tiktok_music_trending (DIRECT_POST only). Returns a publish_id for tiktok_publish_status. PUBLISH QUOTAS per account, enforced before TikTok is called: at most 5 posts per minute and 13 posts per 24 hours, both rolling (TikTok's own ceiling is 6/minute and 15/day). A rejection returns code=cadence_burst or cadence_daily plus retry_after_seconds — wait that long instead of retrying, since retrying sooner only earns another rejection. Failed attempts and drafts do not consume quota; a post TikTok accepted does. Duration, frame size and frame rate are measured from the media file itself by tiktok_prepare_publish, before a publish slot is spent — there is no duration argument, never ask the user for one. music_sound_volume, video_original_sound_volume, music_sound_start and music_sound_end apply only together with music_sound_id and only to videos; without a track, or on a photo post, they are ignored. MEDIA LIMITS — check before calling, and convert or downscale locally if a file does not comply; a rejected file costs a full convert-and-re-upload round trip, and TikTok rejects some files only asynchronously, after the post was submitted. Photos: JPEG or WebP only (PNG is rejected by TikTok, and Higgsfield image generation emits PNG — convert first), each at most 20 MB, resolution must fit within 1920x1080 or 1080x1920, up to 35 images.
