How the connection works
Coros runners tend to be loyal for a reason: the battery lasts, the data is clean, and the training tools respect the sport. Coros connects to Wellness Project directly. Coros also has its own official MCP server that carries Coros data and nothing else, which is a separate path from the one in this guide.
You authorize your Coros account once, from Settings and then Devices in Wellness Project. Wellness Project brings in your steps, resting heart rate, overnight HRV, and watch-recorded workouts, structures the entries into a proper training history, and exposes it to Claude and ChatGPT through a single MCP connection. No phone health hub is needed. Stated plainly, the route is Coros to Wellness Project to Claude or ChatGPT.
Set it up in five steps
Two links do the work: Coros into Wellness Project, and the AI onto Wellness Project. Work through them in order.
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 in Wellness Project
In Wellness Project open Settings, then Devices, choose Coros, sign in to Coros and approve. Wellness Project imports roughly the last three months of history on first connection, then adds new steps, resting heart rate, overnight HRV, and watch-recorded workouts automatically.
Optional: add Apple Health or Health Connect
The direct connection works without a phone health hub. If you also want anything the Coros app itself writes to Apple Health (iPhone) or Google Health Connect (Android), such as sleep where the Coros app shares it, connect that hub in Wellness Project as well.
Add the Wellness Project MCP connector to Claude or ChatGPT
Add Wellness Project as a connector in Claude (via MCP) or ChatGPT (via the plugin). That single connector is the entire AI integration, and it is the same one whether your data came from a Coros, a phone, or a ring. There is no separate Coros step in the AI connector.
Ask about your running in plain language
Ask Claude or ChatGPT whether your mileage is ramping too fast, how your heart rate behaved on your last long run, or whether recovery kept pace with a hard week. The AI reads your structured Coros history and answers against it.
After those two links are set, the pipe runs itself. New data arrives in Wellness Project automatically after Coros sends it, without you touching anything.
Why the direct connection suits training
Coros users care about a training block holding together, not about a logo on a partner page. The direct connection serves that. Your workouts, resting heart rate, and overnight HRV sit in one place next to your nutrition and the rest of your health record, with no phone health hub in the middle.
