Connect ChatGPT to your Apple Health data
HealthBridge holds your Apple Health data in your own account. ChatGPT reads it only once you attach it here, and only what you have chosen to store.
You need the iPhone app first. It is what creates the account and what puts your Apple Health data in it, so there is nothing for ChatGPT to read until it has run once.
1. Add the connector
In ChatGPT, go to Settings → Security and login → Developer mode, then chatgpt.com/plugins → +, then add a custom connector with this address:
https://health.mtnlabs.ai/mcp
2. Sign in with the identity you already use
Pick the same sign-in you used in the iPhone app — Apple, Google or GitHub. Same identity, same account, nothing else to do.
3. Ask it something
“How has my sleep been this month?” is a good first question: it tells you immediately whether the sync worked.
What ChatGPT can see
Only the account you attach it to: the Health categories you allowed in the app, plus anything you log there yourself. The first sync brings your history over and everything after that is incremental. You can revoke this connector, or delete every row of the data, from inside the app at any time.
