Fathom for AI agents

Fathom is an AI meeting assistant that records, transcribes, and summarizes calls, giving teams searchable notes after every meeting instead of relying on manual note-taking. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

04 · AUTH AND DATA

How Fathom connects.

Users sign in to Fathom on Arc0 Connect and approve the scopes you request. Build with Arc0’s Fathom OAuth app, or bring your own so the Fathom consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

The same Fathom connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Fathom and Arc0, answered.

Q01

Can I use Fathom with Claude, ChatGPT or Cursor?

Yes. Connect Fathom to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Fathom actions you allow.

Q02

How do users connect Fathom?

Users sign in to Fathom on Arc0 Connect and approve the scopes you request. Build with Arc0’s Fathom OAuth app, or bring your own so the Fathom consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

Q03

Which Fathom actions can my agent take?

7 in total: 5 read, 1 write and 1 destructive, such as “create webhook for meeting content”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Fathom?

Yes. Actions like “delete Webhook” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Fathom too?

Yes. The same Fathom connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
