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.
What agents do in Beamer.
Check unread announcement count
Count unread posts for a user to decide whether to surface a notification badge.
Pull reactions on a release post
Get reactions and comments on a recent post to gauge how users responded to a feature launch.
Review the feed before publishing
Get the current feed to check draft and live posts before a new announcement goes out, avoiding duplicates.
12 Beamer actions, graded by risk.
Every Beamer action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

await arc0.policies.set('beamer', { read: 'allow', write: 'ask', destructive: 'deny', }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
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 →

- API key
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials

Use Beamer from any agent.
Beamer and Arc0, answered.
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.
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.
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.
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.
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.
Plug Beamer into your agent.
