PostFlow

ChatGPT

Connect ChatGPT to a PostFlow workspace as a custom MCP app.

ChatGPT connects by signing in to PostFlow, through developer mode (Plus, Pro, Business and Enterprise plans; workspace admins may need to allow it).

  1. In ChatGPT, open Settings → Apps & Connectors → Advanced settings and turn on Developer mode.

  2. Back in Apps & Connectors, choose Create. Name it PostFlow, set the MCP server URL and authentication OAuth:

    https://postflow.biz.id/api/mcp

  3. Choose Create, then sign in to PostFlow, pick the workspace and access level, and Allow.

  4. In a chat, pick Developer mode from the tools menu, enable PostFlow and ask: “List my PostFlow accounts.”

ChatGPT shows the tool call and asks for confirmation before tools that change data. Menu names can shift as ChatGPT updates its settings; look for “Developer mode” and “custom connectors” if they’ve moved.
