What ChatGPT can and cannot see
ChatGPT reads whatever reaches Wellness Project, and Wellness Project reads the health hub your Garmin already syncs to: Apple Health on iPhone, Google Health Connect on Android. Activities and workouts, heart rate, sleep stages, and daily steps cross that hub cleanly, and they land as structured rows rather than a raw export, so a question can span a training block instead of one screen.
A handful of Garmin-native scores, training status and Body Battery among them, are computed inside Garmin's own app and do not always write out to the hub as standalone values, so those branded numbers can be missing even once everything else is connected. What does come through is the measurement underneath them: the heart rate, pace, and sleep those scores are built from.
None of that requires exporting a file or pasting a screenshot into the chat. Once the hub is feeding Wellness Project, ChatGPT reads the same structured history every time you ask, not a one-off dump from last Tuesday.
Is there a Garmin MCP server?
There is no Garmin MCP server. The path is Garmin to Garmin Connect to Apple Health or Health Connect to Wellness Project to ChatGPT, over one MCP connection. Wellness Project runs that MCP server itself, reading the Garmin history already synced into your phone's health hub and structuring it into training rows ChatGPT can query.
ChatGPT connects to that server once, as a plugin, and from then on any chat can answer against your real Garmin history. There is no Garmin connector to add inside ChatGPT itself, and no CSV import that recreates what a live connection does.
Set it up in five steps
The whole setup runs through your phone's existing health hub, not a Garmin developer portal or an API key you generate yourself.
Get the Wellness Project app
Download Wellness Project for iPhone or Android with the buttons above, or sign in on the web. Signing in with Apple or Google takes one tap, the account is free during early access, and this is the app that stores your synced history and serves it to Claude and ChatGPT over MCP.
Let Garmin Connect write to your phone's health hub
On iPhone, open Garmin Connect, go to Settings and the Apple Health toggle, and turn on the categories you want shared: activities, heart rate, sleep, and steps. On Android, grant Garmin Connect permission to write to Google Health Connect. Garmin Connect keeps syncing your watch exactly as before; it now also deposits that data into the hub.
Connect Wellness Project to that hub
Sign up for Wellness Project on iPhone, Android, or web, then connect Apple Health or Health Connect and grant read permission. From then on, whatever Garmin writes into the hub gets pulled into your Wellness Project history automatically, with no manual export.
Add the Wellness Project MCP connector to ChatGPT
Add Wellness Project as a ChatGPT plugin and authenticate with the key from your account settings. This is the one connection ChatGPT reads your Garmin-sourced data through, so you set it up once rather than pasting a screenshot into every chat.
Ask about your data in plain language
Open a chat and ask. "How has my resting heart rate trended over the last month?" "Did my sleep hold up during my highest-mileage week?" "What does my training load look like against my recovery?" ChatGPT answers from the structured rows Garmin sent through the hub, not a single pasted number.
For the connector itself and the tool surface it exposes to ChatGPT, see the ChatGPT integration page. This guide is the walkthrough; that page is the product.
What to ask ChatGPT once it is connected
The setup pays off once the questions stop being about a single day and start spanning weeks. Because ChatGPT reads structured history instead of a pasted figure, ask it things a screenshot could never answer.
Try "How consistent has my weekly training structure been over the last six weeks?" Try "Compare my training load to my resting heart rate this month and tell me if recovery is keeping up." Try "Which week did my sleep quality drop the most, and what was different about my Garmin activity that week?" Because the same layer holds every device you connect, those answers can draw on Garmin alongside Apple Health or Oura, instead of staying boxed inside one app.
Give ChatGPT your real Garmin history.
Let Garmin Connect write to your health hub, connect Wellness Project, add the ChatGPT plugin, and ask about your actual training data. Free during early access.
