What ChatGPT can see
Once Coros is connected, ChatGPT can see your steps, resting heart rate, overnight HRV, and watch-recorded workouts, including distance, pace, and heart rate. That is enough for it to line up a run against your heart rate or check how your overnight HRV held up after a hard week.
Is there a Coros MCP server?
Yes. Coros runs its own official MCP server at mcp.coros.com/mcp, which carries Coros data and nothing else. The Wellness Project path is Coros to Wellness Project directly, then Wellness Project to ChatGPT, over one MCP connection. Wellness Project runs that MCP server, reading the steps, resting heart rate, overnight HRV, and workouts Coros sends once you authorize your account and structuring them into a training log ChatGPT can query.
Once your Coros account is authorized in Wellness Project, the setup is done and new runs arrive automatically after Coros sends them. You do not need the Coros connector for this path, and there is nothing to rebuild each week.
Set it up in five steps
Two links carry your training data from watch to chat: Coros into Wellness Project, and ChatGPT onto Wellness Project. Set each one up once.
Your setup screen may look different.
AI assistants change their settings and navigation frequently. Menu names and steps can vary by web, desktop, or mobile client, device and operating system, plan, account type, version, and staged rollout. Treat the instructions on this page as a current guide and look for the equivalent Apps, Connectors, Plugins, or MCP controls if your version differs.
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 app has Free Basic, with Pro at $9.99/month, and this is the app that stores your synced history and serves it to Claude and ChatGPT over MCP.
Connect Coros to Wellness Project
In Wellness Project, open Settings > Devices, choose Coros, sign in to Coros, and approve. No phone health hub is needed. Apple Health on iPhone or Health Connect on Android is an optional extra if you also want anything the Coros app itself writes there, such as sleep.
Let the first import finish
On first connection, Wellness Project imports roughly the last three months of your Coros history. After that, new steps, resting heart rate, overnight HRV, and workouts arrive automatically after Coros sends them, organized into a structured training log.
Add the Wellness Project MCP connector to ChatGPT
ChatGPT may require certain plans to access custom MCP, check your plan for details. On the web at chatgpt.com, turn on developer mode under Settings → Apps → Advanced settings, then go to Settings → Apps → Create. Name it Wellness Project, paste https://wellnessproject.ai/api/mcp, choose OAuth, and sign in with your Wellness Project account when prompted. No API key is needed. 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.
Connect Coros to Wellness Project in Settings > Devices, connect ChatGPT once, and ask about the arc of your training instead of one run at a time. Free Basic, with Pro at $9.99/month.
