MCP server FAQ
Is the MCP server included in my plan?
Yes, on every plan and in the free trial. There's no separate fee for MCP or API access.
How do agents authenticate?
Claude and ChatGPT use OAuth: you sign in with Postoni and approve access. Other clients send an API key from Settings as a Bearer token in the Authorization header.
Can an agent publish without approval?
Agent-created posts arrive as drafts by default, so a person approves them before they publish.
Which transport does it use?
Streamable HTTP at https://postoni.com/mcp. Clients that only support stdio can use a small MCP proxy.
