Circleback for AI agents

Circleback connects to meeting recordings and transcripts, letting an agent search past meetings, action items, and related emails and contacts. 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 Circleback connects.

Circleback runs its own MCP server behind OAuth. Arc0 registers the client, users approve access on Arc0 Connect, and your agent reaches Circleback through the same endpoint, policies and audit log as every other app.

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

AUTH: OAuth 2.0 (MCP)
CREDENTIALS: Per-tenant encrypted vault
MODEL SEES: Results only, never credentials
AUDIT LOG: Every call, on every plan

07 · FAQ

Circleback and Arc0, answered.

Q01

Can I use Circleback with Claude, ChatGPT or Cursor?

Yes. Connect Circleback 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 Circleback actions you allow.

Q02

How do users connect Circleback?

Q03

Which Circleback actions can my agent take?

11 in total: 11 read, 0 write and 0 destructive. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Circleback?

Yes. Allow read actions and deny writes in the Circleback policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call Circleback too?

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