Composio MCP

Composio Connect MCP

The Composio MCP server at connect.composio.dev/mcp gives the agent access to 1000+ apps. Composio manages auth and permissions for all connected apps, intelligently routes to the best tool for the task, helps with long context tasks, and enables programmatic tool calling.

How it works

You have 7 meta-tools that orchestrate everything:

1. COMPOSIO_SEARCH_TOOLS — always start here

Discovers the right tools and returns a recommended execution plan. Call this first whenever the user mentions or implies an external app or workflow.

• Pass queries with a use_case describing what the user wants to do
• For complex workflows, split into multiple atomic queries (1 query = 1 tool call)
• Include app names in each query to keep intent scoped (e.g., "fetch Gmail emails", not just "fetch emails")
• Pass known_fields for any IDs, names, or settings the user mentioned
• Use session: { generate_id: true } for new workflows; reuse the returned session_id for follow-up calls
• If the user pivots to a different task, generate a new session

2. COMPOSIO_GET_TOOL_SCHEMAS — inspect before executing

Retrieves full input schemas for tools by slug. Call this when SEARCH_TOOLS doesn't provide a complete schema — never guess or invent input parameters.

3. COMPOSIO_MULTI_EXECUTE_TOOL — run tools (up to 50 in parallel)

Executes discovered tools. Supports parallel execution for independent operations.

• Only batch tools that are logically independent (no output-to-input dependencies)
• Always use valid slugs and schema-compliant arguments from SEARCH_TOOLS
• Ensure an ACTIVE connection exists before executing
• Set sync_response_to_workbench: true if the response may be large
• Include inline references/links (e.g., Slack thread links, GitHub PR URLs) in results

4. COMPOSIO_MANAGE_CONNECTIONS — connect apps

Creates, lists, renames, or removes app connections. Actions:

• add — initiates OAuth, returns a redirect URL to show the user
• list — shows connected accounts with IDs, aliases, statuses
• rename — rename an account alias
• remove — disconnect an account

After initiating a connection, show the auth link to the user as a formatted markdown link, then immediately call COMPOSIO_WAIT_FOR_CONNECTIONS.

5. COMPOSIO_WAIT_FOR_CONNECTIONS — poll until auth completes

Call after showing the auth link from MANAGE_CONNECTIONS. Waits until the connection reaches ACTIVE or FAILED state.

6. COMPOSIO_REMOTE_BASH_TOOL — shell commands in a remote sandbox

For processing large tool responses saved to remote files. Use jq, awk, sed, grep, etc.

7. COMPOSIO_REMOTE_WORKBENCH — Python scripting in a remote sandbox

For bulk operations, data processing, or multi-tool chains. Persistent Jupyter notebook — state is preserved across calls. Has helper functions like run_composio_tool() and invoke_llm().

Only use the workbench when data is stored in a remote file or you need bulk/scripted execution. If data is already inline, process it directly.

Default workflow

1. Search — COMPOSIO_SEARCH_TOOLS with the user's intent
2. Connect — if no active connection, COMPOSIO_MANAGE_CONNECTIONS → show auth link → COMPOSIO_WAIT_FOR_CONNECTIONS
3. Schema — COMPOSIO_GET_TOOL_SCHEMAS if needed
4. Execute — COMPOSIO_MULTI_EXECUTE_TOOL with discovered tools
5. Process — use workbench/bash only for large or bulk results

Tips

• Always start with SEARCH_TOOLS — never say "I don't have access to X" before searching
• The server knows which apps the user has connected and optimizes search results accordingly
• For cross-app workflows, split into atomic queries and execute independent steps in parallel
• Re-run SEARCH_TOOLS when you need additional tools due to missing details, errors, or a changed use case
• OAuth is fully managed — no API keys needed from the user
