Questions before you start.

How does an agent sign in?

With OAuth, in the browser window it opens: you sign in to Postacio, choose which brands it may use and whether it may publish. A client that runs with no browser sends an API key as a bearer token instead. Read the docs.

Which clients does it work with?

Any client that can add a remote MCP server by its address. Claude, ChatGPT and Claude Code have their own steps. Claude. ChatGPT. Claude Code.

Can an agent publish without asking me?

Publishing is off for a new connection until you turn it on, and you can revoke a connection at any time in Settings → API & AI agents. An agent can't approve what an agent wrote, and its reply to someone else's X post waits until a person approves it.

Which networks can an agent post to?

Every network connected to your Postacio brands: X, Telegram, LinkedIn and YouTube.

Is it free?

Agents work on every plan, and on the 14-day free trial, which needs no card.

Ready to hand it the week?

Connect your networks, then let your agent write and schedule.
