Microsoft Teams Automation via Rube MCP

Automate Microsoft Teams operations through Composio's Microsoft Teams toolkit via Rube MCP.

Toolkit docs : composio.dev/toolkits/microsoft_teams

Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active Microsoft Teams connection via RUBE_MANAGE_CONNECTIONS with toolkit microsoft_teams
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP : Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

1. Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
2. Call RUBE_MANAGE_CONNECTIONS with toolkit microsoft_teams
3. If connection is not ACTIVE, follow the returned auth link to complete Microsoft OAuth
4. Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. Send Channel Messages

When to use : User wants to post a message to a Teams channel

Tool sequence :

1. MICROSOFT_TEAMS_TEAMS_LIST - List teams to find target team [Prerequisite]
2. MICROSOFT_TEAMS_TEAMS_LIST_CHANNELS - List channels in the team [Prerequisite]
3. MICROSOFT_TEAMS_TEAMS_POST_CHANNEL_MESSAGE - Post the message [Required]

Key parameters :

• team_id: UUID of the team (from TEAMS_LIST)
• channel_id: Channel ID (from LIST_CHANNELS, format: '19:...@thread.tacv2')
• content: Message text or HTML
• content_type: 'text' or 'html'

Pitfalls :

• team_id must be a valid UUID format
• channel_id must be in thread format (e.g., '19:abc@thread.tacv2')
• TEAMS_LIST may paginate (~100 items/page); follow @odata.nextLink to find all teams
• LIST_CHANNELS can return 403 if user lacks access to the team
• Messages over ~28KB can trigger 400/413 errors; split long content
• Throttling may return 429; use exponential backoff (1s/2s/4s)

2. Send Chat Messages

When to use : User wants to send a direct or group chat message

Tool sequence :

1. MICROSOFT_TEAMS_CHATS_GET_ALL_CHATS - List existing chats [Optional]
2. MICROSOFT_TEAMS_LIST_USERS - Find users for new chats [Optional]
3. MICROSOFT_TEAMS_TEAMS_CREATE_CHAT - Create a new chat [Optional]
4. MICROSOFT_TEAMS_TEAMS_POST_CHAT_MESSAGE - Send the message [Required]

Key parameters :

• chat_id: Chat ID (from GET_ALL_CHATS or CREATE_CHAT)
• content: Message content
• content_type: 'text' or 'html'
• chatType: 'oneOnOne' or 'group' (for CREATE_CHAT)
• members: Array of member objects (for CREATE_CHAT)

Pitfalls :

• CREATE_CHAT requires the authenticated user as one of the members
• oneOnOne chats return existing chat if one already exists between the two users
• group chats require at least one member with 'owner' role
• member user_odata_bind must use full Microsoft Graph URL format
• Chat filter support is very limited; filter client-side when needed

3. Create Online Meetings

When to use : User wants to schedule a Microsoft Teams meeting

Tool sequence :

1. MICROSOFT_TEAMS_LIST_USERS - Find participant user IDs [Optional]
2. MICROSOFT_TEAMS_CREATE_MEETING - Create the meeting [Required]

Key parameters :

• subject: Meeting title
• start_date_time: ISO 8601 start time (e.g., '2024-08-15T10:00:00Z')
• end_date_time: ISO 8601 end time (must be after start)
• participants: Array of user objects with user_id and role

Pitfalls :

• end_date_time must be strictly after start_date_time
• Participants require valid Microsoft user_id (GUID) values, not emails
• This creates a standalone meeting not linked to a calendar event
• For calendar-linked meetings, use OUTLOOK_CALENDAR_CREATE_EVENT with is_online_meeting=true

4. Manage Teams and Channels

When to use : User wants to list, create, or manage teams and channels

Tool sequence :

1. MICROSOFT_TEAMS_TEAMS_LIST - List all accessible teams [Required]
2. MICROSOFT_TEAMS_GET_TEAM - Get details for a specific team [Optional]
3. MICROSOFT_TEAMS_TEAMS_LIST_CHANNELS - List channels in a team [Optional]
4. MICROSOFT_TEAMS_GET_CHANNEL - Get channel details [Optional]
5. MICROSOFT_TEAMS_TEAMS_CREATE_CHANNEL - Create a new channel [Optional]
6. MICROSOFT_TEAMS_LIST_TEAM_MEMBERS - List team members [Optional]
7. MICROSOFT_TEAMS_ADD_MEMBER_TO_TEAM - Add a member to the team [Optional]

Key parameters :

• team_id: Team UUID
• channel_id: Channel ID in thread format
• filter: OData filter string (e.g., "startsWith(displayName,'Project')")
• select: Comma-separated properties to return

Pitfalls :

• TEAMS_LIST pagination: follow @odata.nextLink in large tenants
• Private/shared channels may be omitted unless permissions align
• GET_CHANNEL returns 404 if team_id or channel_id is wrong
• Always source IDs from list operations; do not guess ID formats

5. Search Messages

When to use : User wants to find messages across Teams chats and channels

Tool sequence :

1. MICROSOFT_TEAMS_SEARCH_MESSAGES - Search with KQL syntax [Required]

Key parameters :

• query: KQL search query (supports from:, sent:, attachments, boolean logic)

Pitfalls :

• Newly posted messages may take 30-60 seconds to appear in search
• Search is eventually consistent; do not rely on it for immediate delivery confirmation
• Use message listing tools for real-time message verification

Common Patterns

Team and Channel ID Resolution

1. Call MICROSOFT_TEAMS_TEAMS_LIST
2. Find team by displayName
3. Extract team id (UUID format)
4. Call MICROSOFT_TEAMS_TEAMS_LIST_CHANNELS with team_id
5. Find channel by displayName
6. Extract channel id (19:...@thread.tacv2 format)

User Resolution

1. Call MICROSOFT_TEAMS_LIST_USERS
2. Filter by displayName or email
3. Extract user id (UUID format)
4. Use for meeting participants, chat members, or team operations

Pagination

• Teams/Users: Follow @odata.nextLink URL for next page
• Chats: Auto-paginates up to limit; use top for page size (max 50)
• Use top parameter to control page size
• Continue until @odata.nextLink is absent

Known Pitfalls

Authentication and Permissions :

• Different operations require different Microsoft Graph permissions
• 403 errors indicate insufficient permissions or team access
• Some operations require admin consent in the Azure AD tenant

ID Formats :

• Team IDs: UUID format (e.g., '87b0560f-fc0d-4442-add8-b380ca926707')
• Channel IDs: Thread format (e.g., '19:abc123@thread.tacv2')
• Chat IDs: Various formats (e.g., '19:meeting_xxx@thread.v2')
• User IDs: UUID format
• Never guess IDs; always resolve from list operations

Rate Limits :

• Microsoft Graph enforces throttling
• 429 responses include Retry-After header
• Keep requests to a few per second
• Batch operations help reduce total request count

Message Formatting :

• HTML content_type supports rich formatting
• Adaptive cards require additional handling
• Message size limit is approximately 28KB
• Split long content into multiple messages
