How the integration actually works
Start with the honest part, because it is the whole point. There is no Polar MCP server you connect to. Instead, your Polar account talks directly to Wellness Project via our native integration, and we serve that data directly to Claude or ChatGPT.
Wellness Project reads your data via a native integration. It takes the training sessions, heart rate, sleep, nightly recovery, and daily activity Polar measured, structures them into one continuous history, and serves that history to Claude and ChatGPT over a single MCP connection. So the real chain is Polar, then Wellness Project, then Claude or ChatGPT.
Why a native connection is better
A direct native integration is the sturdiest design. Wellness Project connects directly to Polar, so there is no phone hub to babysit and nothing to relay through Apple Health or Health Connect. When Polar records a new session, it flows into your history on its own schedule.
It also means every other device you own can join the same history. Your Polar watch reports the training session and heart rate, an Oura ring reports the sleep, a Withings scale reports body composition, and they all land in Wellness Project. Your AI coach sees training load next to recovery next to body composition, instead of one number in isolation.
Set it up in three steps
The setup is simple thanks to the native connection. Connect your Polar account, then point Claude or ChatGPT at Wellness Project.
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.
Connect Polar natively
In the Wellness Project app, connect your Polar account natively. We read what Polar measured and structure it into one history: training sessions, heart rate, sleep, nightly recovery, and daily activity, all keyed to your baseline. This is a direct, native connection to Polar.
Add the MCP connector to Claude or ChatGPT
Add the Wellness Project connector to Claude (via MCP) or ChatGPT (via the plugin). One connection is all it takes, and it covers everything in your account, including Polar. Claude and ChatGPT are the two AI integrations Wellness Project supports today.
Ask your training questions
Ask Claude or ChatGPT how your weekly training load is trending, whether your easy sessions are actually easy by heart rate, or how your recovery tracked against your hardest weeks. It answers from your structured Polar history, not a single session.
That is the entire flow. A native Polar integration on our side, no real-time promise we cannot keep. Freshness tracks whenever Polar syncs, and Wellness Project reads it from there.
Put your Polar training in front of an AI coach.
Connect your Polar account directly to Wellness Project and let Claude or ChatGPT read your training sessions, sleep, and recovery against your baseline. Free Basic, with Founder Pro at $4.99/month through October 15.
