Fathom API and MCP server

Fathom only lets code read calls, so it cannot complete action items, share calls or change settings. Sign in to Fathom once in your own Cloud Browser, and your AI agent does the work there for you. The same tools work over MCP for agents and as a REST API for scripts.

Fathom has no API for this. So we run one for you.

How do I connect Fathom to Claude, ChatGPT or my code?

AI agents connect over MCP, scripts call the REST API. Both reach the same 14 tools with one API key.

For AI agents: MCP

Add Cotlet to your agent once. Fathom and every other app you connect show up as its tools.

    Paste the snippet for your client. The same server and key serve every app you connect, so you do this once.

For scripts: REST API

Every tool is an endpoint under /api/v1/fathom-video with its own method and path, such as POST /api/v1/fathom-video/calls/{call_id}/share, with the same API key. Our open-source repo has ready scripts to start from.

REST API docs

What can the Fathom API and MCP server do?

14 tools on your own Fathom account. Agents call them as operations of the MCP tools fathom_video_read and fathom_video_write; scripts call each one at its own REST endpoint, with the same inputs and answers.

Security overview

How much do the Fathom API and MCP server cost?

One price for both: a tool call costs the same over MCP or REST. Free 7-day trial with 2,000 credits, no card needed. Then one-time credit packs, no subscription, valid 12 months. Most calls use 25 credits, and your Cloud Browser uses 50 credits a day while Fathom is enabled for agents, so 20 calls a day come to 550 credits.

Questions

Does Fathom have an API?

Fathom has a REST API and an official MCP server, but both only read your calls (checked 22 Oct 2026). The API lists meetings and returns summaries, transcripts and action items, requests recording downloads and manages webhooks. Its reference has no endpoint that edits an action item, shares a call or changes a setting.

How do I get access?

Sign up free, open Fathom under Integrations in the console and press Request access. Your free trial starts with your account, no card needed.

Is the MCP server different from the API?

No, only the way in. Cotlet builds each integration as a REST API and puts an MCP server on top, so both have the same 14 tools, the same inputs and answers, one API key and one price. AI agents such as Claude, ChatGPT or Cursor use MCP; scripts, cron jobs and HTTP steps in n8n, Make or Zapier use the REST API.

What is the Cloud Browser?

Your own Chrome that Cotlet runs for you in the EU, around the clock. You open it from the console, sign in to Fathom yourself and press Enable for agents. Your agent's calls go through it, from its IP with its cookies, so Fathom sees the browser you signed in with. Password saving is off and the profile is stored encrypted with AES-256-GCM.

Can my agent act without asking me?

Not on anything that reaches other people: add_action_item, share_call, remove_call_access, set_link_access, regenerate_summary, update_settings, delete_call wait for your OK by default. You can switch that off per tool for scheduled runs.

Which Fathom plan do I need?

Cotlet works in your own Fathom account on any plan, and your plan still sets what Fathom offers. Fathom documents Auto-Generate Action Items and summary customization as Premium and Team features, so on Free those tools return nothing or an error. Fathom says API access, keys and webhooks are on all plans.

Which calls can my agent open?

The calls your account can open: ones you recorded and ones shared with you or your team. Fathom keeps a private call visible to its host only, and an admin sees other people's calls only where the call is shared with them. Delete and sharing tools follow your role on each call.

Should I use a Fathom MCP server from GitHub instead?

Pick one if you want the code on your own computer and do not mind the upkeep: you install it, sign it in and fix it when Fathom changes. Pick Cotlet if you want it hosted and kept working for you.

Can I use it in n8n, Make or Zapier?

Yes. Add https://cotlet.dev/mcp/v1 in n8n's MCP Client node, or call the REST endpoints from an HTTP step in Make or Zapier.

Who runs Cotlet?

Cotlet is run by Take Group, a Polish software company working since 2019. Take Group runs about 3,200 websites on its own systems and has its own DevOps team for infrastructure security. We built and used integrations like this inside the company for years before opening them as Cotlet.

Is Cotlet affiliated with Fathom?

No. Cotlet is independent and not affiliated with Fathom.
