What ChatGPT can and cannot see
Once the hub is connected, ChatGPT can see whatever the Coros app hands to Apple Health or Health Connect: your workouts, distance, pace, heart rate, and sleep. That is enough for it to line up a run against your heart rate or check how sleep held up after a hard week.
What ChatGPT cannot see is the layer Coros keeps for itself. Training Load, EvoLab fitness and freshness scores, and similar Coros-proprietary readings are computed inside the Coros app and often do not export to the phone's health hub. If a metric never reaches Apple Health or Health Connect, Wellness Project has no way to read it, and neither does ChatGPT.
Is there a Coros MCP server?
There is no Coros MCP server. The path is Coros to the Coros app to Apple Health or Health Connect to Wellness Project to ChatGPT, over one MCP connection. Wellness Project runs that MCP server, reading the workouts, heart rate, and sleep the Coros app writes to your phone's health hub and structuring them into a training log ChatGPT can query.
Once your Coros app is writing to the hub and Wellness Project is reading it, the setup is done and that one connection carries every new run automatically. There is no Coros connector to add inside ChatGPT itself, and nothing to rebuild each week.
Set it up in five steps
Three links carry your training data from watch to chat: Coros into the hub, Wellness Project onto the hub, and ChatGPT onto Wellness Project. Set each one up once.
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 the Coros app write to your phone's health hub
In the Coros app, turn on the export to Apple Health on iPhone or Health Connect on Android, and allow it to write workouts, heart rate, and sleep. Sync your watch once so recent runs land in the hub before you connect anything else.
Connect Wellness Project to that hub
In Wellness Project, connect Apple Health or Health Connect and grant read access to workouts, heart rate, sleep, and pace. Wellness Project now organizes whatever Coros deposited into a structured training log.
Add the Wellness Project MCP connector to ChatGPT
Add Wellness Project as a plugin in ChatGPT and authenticate with the key from your account settings. This one connection is how ChatGPT reads your Coros history from here on, so you set it up once rather than pasting a workout each time.
Ask about your data in plain language
Open a chat and ask about your training. ChatGPT pulls the structured rows behind your Coros runs and answers from your real history instead of a single pasted screen.
What to ask ChatGPT once it is connected
The prompts worth asking are the ones a single Coros screen cannot answer, because they span weeks instead of one activity.
Try "How has my easy-pace heart rate trended over this training block?" or "Did my long-run pace hold up as my weekly mileage went up?" or "Which week this training cycle had the biggest gap between planned and actual mileage?" ChatGPT answers from your structured Coros history, not a screenshot of today's run.
Let ChatGPT read your whole Coros training block.
Relay Coros through Apple Health or Health Connect into Wellness Project, connect ChatGPT once, and ask about the arc of your training instead of one run at a time. Free during early access.
