What Claude can and cannot see
Once the hub is connected, Claude 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 Claude 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 Claude.
Is there a Coros MCP server?
Yes. Coros launched an official MCP server in 2026, and its setup guide has Claude users add mcp.coros.com/mcp as a custom connector. That path carries Coros data and nothing else.
Wellness Project is the path for the whole picture. The Coros app writes workouts, heart rate and sleep into Apple Health or Health Connect, Wellness Project reads that hub and structures it into a training log next to your nutrition, injuries, labs and sleep from every other source, and one Wellness Project MCP connection serves all of it to Claude. Once the Coros app is writing to the hub and Wellness Project is reading it, that connection carries every new run automatically, with 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 Claude 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 Founder Pro at $4.99/month through October 15, 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 Claude
In claude.ai, add wellnessproject.ai/api/mcp as a custom connector and authorize it through your Wellness Project account. Claude Desktop syncs the connector from claude.ai. This is the single MCP connection in the whole path.
Ask about your data in plain language
Open a chat and ask about your training. Claude pulls the structured rows behind your Coros runs and answers from your real history instead of a single pasted screen.
What to ask Claude 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?" Claude answers from your structured Coros history, not a screenshot of today's run.
Let Claude read your whole Coros training block.
Relay Coros through Apple Health or Health Connect into Wellness Project, connect Claude once, and ask about the arc of your training instead of one run at a time. Free Basic, with Founder Pro at $4.99/month through October 15.
