# Methods [#methods]

## authorize() [#authorize]

Initiate an authorization flow for a toolkit.
Returns a ConnectionRequest with a redirect URL for the user.

Pass `experimental: { accountType: 'SHARED', aclConfigForShared }` to
create a SHARED connection with a per-user ACL in one flow. Default
behaviour (omit the block) creates a PRIVATE connection.

Experimental — shape may change in future releases.

`aclConfigForShared` is validated against the same caps as
`composio.connectedAccounts.link()` (≤1000 entries per list, each
`userId` 1..256 characters). Invalid input throws `ValidationError`
at the SDK boundary.

```typescript
async authorize(toolkit: string, options?: { callbackUrl?: string; alias?: string; experimental?: { accountType?: ConnectedAccountType; aclConfigForShared?: ConnectedAccountAclConfig; }; }, requestOptions?: ComposioRequestOptions): Promise
```

**Parameters**

| Name              | Type                                                                                                                                                    |

## execute() [#execute]

Execute a tool within the session.

For custom tools, accepts the original slug (e.g. "GREP") or the
full slug (e.g. "LOCAL\_GREP"). Custom tools are executed in-process;
remote tools are sent to the Composio backend.

```typescript
async execute(toolSlug: string, arguments_?: Record<string, unknown>, options?: ToolRouterSessionExecuteOptions, requestOptions?: ComposioRequestOptions): Promise
```

**Parameters**

| Name              | Type                              | Description                |

| `options?`        | `ToolRouterSessionExecuteOptions` | Optional execution options |
| `requestOptions?` | `ComposioRequestOptions`          |                            |

**Returns**

`Promise` — The tool execution result

***

## proxyExecute() [#proxyexecute]

Proxy an API call through Composio's auth layer using the session's connected account.
The backend resolves the connected account from the toolkit within the session.

```typescript
async proxyExecute(params: SessionProxyExecuteParams, requestOptions?: ComposioRequestOptions): Promise
```

**Parameters**

| Name              | Type                        | Description                                                                      |

Search for tools by semantic use case.
Returns relevant tools for the given query with schemas and guidance.

```typescript
async search(params: { query: string; toolkits?: string[]; }, requestOptions?: ComposioRequestOptions): Promise
```

**Parameters**

| Name              | Type                                        |
| ----------------- | ------------------------------------------- |
| `params`          | `\{ query: string; toolkits?: string[]; \}` |
| `requestOptions?` | `ComposioRequestOptions`                    |

**Returns**

`Promise`

***

## toolkits() [#toolkits]

Query the connection state of toolkits in the session.
Supports pagination and filtering by toolkit slugs.

```typescript
async toolkits(options?: ToolRouterToolkitsOptions, requestOptions?: ComposioRequestOptions): Promise<{ cursor: string | undefined; items: { connection?: { authConfig?: ... | ...; connectedAccount?: { id: ...; status: ... }; isActive: boolean }; isNoAuth: boolean; logo?: string; name: string; slug: string }[]; totalPages: number }>
```

**Parameters**

| Name              | Type                        |
| ----------------- | --------------------------- |
| `options?`        | `ToolRouterToolkitsOptions` |
| `requestOptions?` | `ComposioRequestOptions`    |

**Returns**

`Promise<\{ cursor: string \| undefined; items: \{ connection?: \{ authConfig?: ... \| ...; connectedAccount?: \{ id: ...; status: ... \}; isActive: boolean \}; isNoAuth: boolean; logo?: string; name: string; slug: string \}[]; totalPages: number \}>`

***

## tools() [#tools]

Get the tools available in the session, formatted for your AI framework.
Requires a provider to be configured in the Composio constructor.

When custom tools are bound to the session, execution of COMPOSIO\_MULTI\_EXECUTE\_TOOL
is intercepted: local tools are executed in-process, remote tools are sent to the backend.

```typescript
async tools(modifiers?: SessionMetaToolOptions, requestOptions?: ComposioRequestOptions): Promise>
```

**Parameters**

| Name              | Type                     |

# Composio SDK — Instructions for AI Code Generators

**Purpose:** Enforce only the **current** and **correct** patterns for integrating [Composio](https://composio.dev/) tools into AI agents.
**Scope:** All AI-generated code using Composio must follow these guardrails.

---

## 1. Correct Composio Integration

Composio supports two integration modes: **Native Tools** (with a provider package) and **MCP** (no provider package needed).

### Native Tools

```python
# ✅ CORRECT — Python (defaults to OpenAI)
from composio import Composio

composio = Composio()
session = composio.create(user_id="user_123")
tools = session.tools()
# Pass tools to your agent/LLM framework
```

```typescript
// ✅ CORRECT — TypeScript (defaults to OpenAI)
import { Composio } from "@composio/core";

const composio = new Composio();
const session = await composio.create("user_123");
const tools = await session.tools();
// Pass tools to your agent/LLM framework
```

For other providers, pass the provider explicitly. Provider packages follow the naming convention: `composio_<provider>` for Python, `@composio/<provider>` for TypeScript.

### MCP

Use `session.mcp.url` and `session.mcp.headers` with any MCP-compatible client (Claude Desktop, Cursor, OpenAI Agents, etc.). No provider package needed.

---

## 2. CRITICAL INSTRUCTIONS FOR AI MODELS

### 2.1 — ALWAYS DO THE FOLLOWING

1. **Use `composio.create(user_id)`** to create a session — this is the entry point for all Composio integrations.
2. **Use `session.tools()`** for native tool integration or **`session.mcp.url`** for MCP integration.
3. **Import** from the correct provider package (`composio_<provider>` for Python, `@composio/<provider>` for TypeScript).
4. **Pass `user_id` to `composio.create()`**, not to individual tool calls.

### 2.2 — NEVER DO THE FOLLOWING

1. **Do not** instruct users to manually create auth configs or connected accounts before running.
2. **Do not** import from `composio_openai` / `@composio/openai` when using OpenAI Agents SDK — use `composio_openai_agents` / `@composio/openai-agents` instead.

### 2.3 — DISCOURAGED (do not use unless user explicitly asks)

Do **not** generate `composio.tools.get()`, `composio.tools.execute()`, or `composio.provider.handle_tool_calls()` unless the user explicitly requests direct tool execution. These are a supported but **not recommended** low-level interface.


---

## Terminology Migration (old → current)

If you encounter these terms in error messages, old documentation, or user prompts, translate them to the current equivalents. **Do not use the old terms in generated code or explanations.**

| Old term (v1/v2) | Current term (v3) | In code |
|---|---|---|
| entity ID | user ID | `user_id` parameter |
| actions | tools | e.g., `GITHUB_CREATE_ISSUE` is a *tool* |
| apps / appType | toolkits | e.g., `github` is a *toolkit* |
| integration / integration ID | auth config / auth config ID | `auth_config_id` parameter |
| connection | connected account | `connected_accounts` namespace |
| ComposioToolSet / OpenAIToolSet | `Composio` class with a provider | `Composio(provider=...)` |
| toolset | provider | e.g., `OpenAIProvider` |

If a user says "entity ID", they mean `user_id`. If they say "integration", they mean "auth config". Always respond using the current terminology.
