Connect your fitness data to ChatGPT
Create a custom connector in ChatGPT with the MCP endpoint, then approve the OAuth sign-in. Once connected, ask "What should I do today?" and ChatGPT answers from your own brief, scores and plan.
- 1In ChatGPT, open Settings, then Apps and connectors.
- 2Under Advanced settings, turn on Developer mode if your plan requires it for custom connectors.
- 3Create a connector, name it, and paste the MCP endpoint as the server URL with OAuth authentication.
- 4Sign in when prompted, choose Allow, then select the connector in a new chat.
- ChatGPT's connector settings change often and depend on your plan. If a menu has moved, search the ChatGPT help centre for "custom connectors".
- search and fetch follow the OpenAI deep-research contract, so the server also works for research.

Questions
What can ChatGPT do once connected?
Read your day, trends, goals, teams and week plan. With write permission it can log entries and meals, create metrics, set goals, plan days and write your morning brief.
Can I disconnect it?
Yes. Open Coach in the app and choose Disconnect next to the assistant. Its tokens stop working at once.
Does it see other people's data?
No. It signs in as you and sees only your account, plus the derived team scores your teammates agreed to share.
