Postiz for AI agents

Postiz is an agentic social media scheduling tool for managing posts, building an audience, and capturing leads with AI assistance. Creators and marketers use it to plan content across channels. 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 Postiz connects.

Users add their Postiz 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 Postiz 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

Postiz and Arc0, answered.

Q01

Can I use Postiz with Claude, ChatGPT or Cursor?

Yes. Connect Postiz 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 Postiz actions you allow.

Q02

How do users connect Postiz?

Users add their Postiz 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 Postiz actions can my agent take?

14 in total: 0 read, 14 write and 0 destructive, such as “postsettingstool”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in Postiz?

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

Q05

Can my own backend call Postiz too?

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