fathom-mcp-adapter

Read-only MCP server that exposes Fathom meetings + transcripts as tools, for use by /updateP1 (and other skills) in the TICKETS workspace.

This is a private, standalone adapter: its own git repo, its own .env. It is not part of ia-tooling and does not depend on its stack — it only makes HTTPS calls out to the Fathom REST API (https://api.fathom.ai/external/v1). It was scaffolded by cloning the structure of ia-tooling/services/zendesk-mcp-adapter.

Architecture

The adapter is the MCP server. Internally it calls the Fathom REST API directly (just as the Zendesk adapter calls Zendesk's REST API). MCP servers are not chained to one another.

• Auth: per-user API key sent as the X-Api-Key header. The key is scoped to one user (their own meetings + meetings shared to their Team), which provides data isolation between teammates. Rate limit: 60 req/min.
• The adapter returns the raw transcript. The who/what/when summary is produced by the /updateP1 skill, never by a tool here.
• There is no title/keyword search in the Fathom API. To find a specific meeting, list recent meetings (optionally narrowing by created_after / recorded_by) and let the skill filter by title/date/invitee.

Tools

Tool	Purpose
fathom_health	Config/connectivity check (makes one authenticated call).
fathom_list_recent_meetings	List recent meetings, newest first. Filters: created_after, created_before, recorded_by, invitee_domains, meeting_type.
fathom_get_latest_meeting	The single most recent meeting (the 90% case for /updateP1).
fathom_get_transcript	Raw transcript for a recording_id.

Each meeting record includes title, recording_id, created_at, url (private, login-gated) and share_url (team-shareable). For the internal timeline reference use share_url, never url.

Setup

npm install
cp .env.example .env   # then fill in FATHOM_API_KEY
npm test
npm start              # speaks MCP over stdio

FATHOM_API_KEY must come from .env (which is git-ignored) — never hardcode it.

Wiring into the TICKETS MCP session

Build the image and add a fathom entry to the TICKETS .mcp.json, alongside zendesk / vectordb / github. It does not need the ia-tooling_default network (HTTPS egress only).

docker build -t fathom-mcp-adapter .

// .mcp.json (TICKETS)
{
  "mcpServers": {
    "fathom": {
      "command": "docker",
      "args": ["run", "--rm", "-i", "--env-file", "/ABSOLUTE/PATH/TO/.env", "fathom-mcp-adapter"]
    }
  }
}

Fallback

If the Fathom MCP server is down, /updateP1 falls back to the manual "paste-me-the-transcript" mode rather than blocking (same pattern as zendesk/vectordb).
