Composio MCP Server

Connect AI agents to 1000+ apps (Gmail, Slack, GitHub, Linear, and more) with managed authentication and tool-calling.

Composio is a remote, streamable-HTTP MCP server. Connecting opens an OAuth login (login.composio.dev); no API keys to paste, nothing to run locally.

https://connect.composio.dev/mcp

VS Code

code --add-mcp '{"name":"composio","type":"http","url":"https://connect.composio.dev/mcp"}'

Any other MCP client: point it at the remote server https://connect.composio.dev/mcp.
