Connect to ChatGPT

Web, desktop, and mobile. Add Planner as a plugin via Developer Mode — the connection syncs across all your devices.

Setup

Open Plugins in the sidebar (or go to chatgpt.com/plugins).
Click the + button in the top right corner.
Enter the server URL: https://planner.monopoly-gold.com/_mcp
ChatGPT discovers the OAuth configuration automatically. A browser window opens — sign in with Google.
Planner appears under Installed; its tools become available in your chats — including mobile.

Open a new chat and ask ChatGPT to list your projects:

in chat

> list my planner projects
  → planner:list-projects  returns your projects (empty array on a fresh account)
