ChatGPT setup
Connect in developer mode
- In ChatGPT, open Settings → Security and login and turn on Developer mode. If the switch is unavailable, your workspace administrator must allow it.
- Open Settings → Plugins, or go directly to chatgpt.com/plugins, then select the plus button to create a developer-mode app.
- Name the app miracle.fyi. Describe it as your to-do, project, habit, pact, goal, 3·6·9, Notes, Vision, North Star, and Time on Earth assistant. Enter the exact MCP server URL:
https://miracle.fyi/mcp. - Select Create and confirm ChatGPT discovers 56 tools.
- Open a new chat, select + → More → miracle.fyi, and ask: Which Miracle account and timezone are connected? This first tool use opens the authorization window.
- Sign in to miracle.fyi and review the requested scopes. The identity check needs
mcp:read. If a later request needsmcp:write, ChatGPT asks you to authorize it and you can decline.
ChatGPT should use get_profile before its first write. Miracle OAuth scopes define what the app is allowed to do. ChatGPT's confirmation controls under Settings → Apps define how often it asks before calling an allowed tool. Create, refresh, or remove the developer app under Settings → Plugins. These steps follow OpenAI's current developer-mode app instructions.
