Microsoft Teams

Use this guide to configure Microsoft Teams scopes, fix stale OAuth metadata, connect through MCP, and troubleshoot chat or tool execution.

Configure Microsoft Teams scopes and Azure consent

Check delegated permissions against the latest tool version. For Microsoft Teams scope checks, call /api/v3/tools/get_scopes_required with the exact tool slug and include toolkit_versions[microsoft_teams]=latest when needed. Without the explicit toolkit version, the API may return data from the old 00000000_00 version.

Use the delegated scopes required by each action. MICROSOFT_TEAMS_CHATS_GET_ALL_CHATS can use Chat.ReadBasic, Chat.Read, or Chat.ReadWrite. MICROSOFT_TEAMS_CREATE_MEETING requires OnlineMeetings.ReadWrite. Confirm exact required scopes with the latest versioned scope endpoint before changing auth config scopes.

Use customer-owned Azure credentials when custom scopes are needed. For Microsoft Teams, recommend using the customer's own Azure/Microsoft developer app credentials when custom scopes are needed. Additional scopes should be added in the Microsoft app, and admin consent may need to be granted in Azure before the connection has usable permissions.

Fix the invalid OAuth scope ChannelMessage.Read.Group

If Microsoft Teams OAuth fails before consent with:

AADSTS650053: The application asked for scope 'ChannelMessage.Read.Group' that doesn't exist on the resource Microsoft Graph.

treat ChannelMessage.Read.Group as the wrong auth layer for the Composio delegated OAuth flow. It is a Microsoft Teams resource-specific consent (RSC) permission, not a normal Microsoft Graph OAuth scope to include in an OAuth /authorize URL.

Debug steps:

• Check whether the customer is using v3 base/default tool metadata or old Teams slugs.

• MICROSOFT_TEAMS_TEAMS_GET_MESSAGE on v3 base can return ChannelMessage.Read.Group; the latest/v3.1 replacement is MICROSOFT_TEAMS_GET_CHANNEL_MESSAGE.

• Use v3.1 or pass toolkit_versions[microsoft_teams]=latest when fetching tools/scopes.

• Remove ChannelMessage.Read.Group from the OAuth auth config scopes and use ChannelMessage.Read.All, Group.Read.All, or Group.ReadWrite.All according to the latest tool scope response.

• If an existing auth config already includes the invalid scope, update or recreate it and reconnect. Existing connected accounts may need refresh/reconnect depending on how the customer propagates scope changes.

Minimal stale-path repro:

curl --globoff 'https://backend.composio.dev/api/v3/tools/MICROSOFT_TEAMS_TEAMS_GET_MESSAGE' \
  -H 'x-api-key: <key>'

Expected stale response includes version: "00000000_00" and scopes: ["ChannelMessage.Read.Group"].

Clean path:

curl --globoff 'https://backend.composio.dev/api/v3.1/tools/MICROSOFT_TEAMS_GET_CHANNEL_MESSAGE' \
  -H 'x-api-key: <key>'

Expected clean response includes ChannelMessage.Read.All, not ChannelMessage.Read.Group.

Connect Teams through MCP and Tool Router

Match the MCP URL user ID to the connected account. For Microsoft Teams MCP, the user ID in the MCP server URL/query params must match the user ID attached to the connected account. If the connection is bound to an email/GUID, use that value in the MCP URL or create a new server/connection with the desired user ID.

Pass Tool Router memory as a list under the toolkit key. When passing Tool Router memory for Microsoft Teams, use a real list under the microsoft_teams key, for example "memory": { "microsoft_teams": ["Session id..."] }. Do not pass escaped square brackets as a string.

Create chats and troubleshoot tool execution

Pass two users with the correct OData bind format for one-on-one chats. For Microsoft Teams one-on-one chat creation, pass two users, not one. Also make sure the OData bind payload uses the correct role and bind-data format expected by Microsoft Graph.

Validate user IDs and chat membership for 400/403/404 errors. For MICROSOFT_TEAMS_LIST_USER_CHAT_MESSAGES, a 400 commonly means user_id was not passed as a GUID or UPN. For chat members tools, 403/404 often means the connected user is not part of the meeting chat or the chat ID is not in that user's scope. Use MICROSOFT_TEAMS_LIST_USERS to find valid user IDs and verify the connected user is a participant in the target chat.

Increase limit when the tool list stops at 20. When fetching Microsoft Teams tools by toolkit, the default list may return only 20 tools. Increase the limit parameter or search for exact tool slugs to retrieve the full set.

Prefer replacement slugs over restored deprecated aliases. Some old Microsoft Teams slugs were deleted during cleanup and then restored with a deprecated flag and descriptions pointing to the correct replacement slugs. If a Teams slug suddenly disappears or changes, check the latest toolkit version/changelog and prefer the replacement slug.
