Beehiiv for AI agents

beehiiv is a newsletter platform for writing, sending, and growing publications, used by creators and media teams to manage subscribers, posts, and automations. 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 Beehiiv connects.

Users add their Beehiiv 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 Beehiiv 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

Beehiiv and Arc0, answered.

Q01

Can I use Beehiiv with Claude, ChatGPT or Cursor?

Yes. Connect Beehiiv 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 Beehiiv actions you allow.

Q02

How do users connect Beehiiv?

Users add their Beehiiv 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 Beehiiv actions can my agent take?

11 in total: 6 read, 5 write and 0 destructive, such as “create Segment”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Beehiiv?

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

Q05

Can my own backend call Beehiiv too?

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