Fathom MCP Server

A read-only Model Context Protocol (MCP) server for accessing Fathom AI API endpoints (meetings, recordings, transcripts, summaries, teams, team members) via GET operations. Built with FastMCP.

This implementation provides streamlined access to Fathom meeting data while minimizing API consumption. It is optimized for efficiency and simplicity, using the toon output format for less token usage and better LLM processing.

Features

• List Meetings: Retrieve meetings with optional filtering and inclusion of transcripts/summaries

• Get Summary: Retrieve markdown summary for a specific recording

• Get Transcript: Retrieve transcript for a specific recording

• List Teams: Retrieve all teams

• List Team Members: Retrieve team members with optional team filtering

• TOON Format Support: Optimized output format for reduced token usage and better LLM processing

Requirements

• Python 3.10+

• Fathom API key

• FastMCP 2.0+
