How to connect Postiz to Grok Bot
💬Install: Custom MCP Grok Bot has no settings form for custom MCP servers. You ask your Bot in chat.
- Copy the MCP URL above. It has to be public HTTPS (streamable HTTP or SSE). A localhost address will not work.
- Tell your Bot in chat: “Add this MCP server: https://api.postiz.com/mcp”.
- The Bot confirms the details and sets it up. If asked, finish the Postiz social scheduler sign-in.
- Its tools are available from your next message.
We have not checked whether Postiz also exists as a built-in plugin. If you see it in Connect apps, you can add it there instead (verify in-app).
