polar-flow-server is a self-hosted health analytics platform for Polar wearable owners that syncs sleep, HRV, activity, and other data permanently into a PostgreSQL database, computing personal baselines rather than relying on generic thresholds. It includes a built-in MCP server with OAuth sign-in so an AI assistant can answer questions about recovery and training readiness.
