Beamer for AI agents

Beamer lets companies post product updates and announcements inside their own app or website, used by product teams to keep users informed without a separate blog. 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 Beamer connects.

Users add their Beamer api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same Beamer 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

Beamer and Arc0, answered.

Q01

Can I use Beamer with Claude, ChatGPT or Cursor?

Yes. Connect Beamer 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 Beamer actions you allow.

Q02

How do users connect Beamer?

Users add their Beamer api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which Beamer actions can my agent take?

12 in total: 12 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 Beamer?

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

Q05

Can my own backend call Beamer too?

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