FAQ from Composio MCP Server

What does this server do?

It acts as a bridge between the Model Context Protocol and Composio’s tools/actions, enabling language models to call applications like Gmail and Linear in a structured way.

What prerequisites are needed?

Node.js version 16 or higher and a valid Composio API key (sign up at app.composio.dev).

How do I configure the server for use?

Set the COMPOSIO_API_KEY environment variable and point your MCP client to the built index.js file (e.g., node /path/to/composio-mcp-server/build/index.js).

Which applications are supported?

The README explicitly mentions Gmail and Linear, and states “various Composio applications” are available.

Where does my data live?

The README does not describe data storage or handling; all data is processed through Composio’s API as called via the server.
