Connects AI agents to Polar wearable data through the AccessLink v4 API. Handles OAuth locally so tokens never leave your machine. Exposes 16 fine-grained scopes covering Nightly Recharge, training load, sleep, HRV, PPI samples, continuous heart rate, fitness tests, and training sessions. GPS coordinates are redacted by default. Ships with tools like polar_daily_summary and polar_weekly_summary for quick recovery and training briefs, plus granular methods for pulling continuous samples, sleep wake vectors, and orthostatic test results. Run npx polar-mcp-unofficial setup to configure your AccessLink client, then auth to complete the OAuth flow. Useful if you're coaching yourself with Claude and want structured physiology data without copy-pasting from Polar Flow.
