Polar Monitoring MCP
A read-only MCP connection for Sites, Device/Sensors, persisted measurements, history, freshness, and control state.
Connect
Use this server's /mcp URL in ChatGPT, Codex, or an OAuth-capable MCP client. The client discovers OAuth automatically. Connect a Polar external API key; its Group assignments determine the Sites available to the MCP.
Safety
The published tool set cannot activate controls, modify configuration, acknowledge alerts, or change Polar data. Control-state reads are GET-only and are clearly identified when Polar may contact hardware.
History limits
History requests are bounded, support at most 20 measurements at once, and responses are capped at 2,000 points. Current measurement values are the newest persisted V3 history points, not physical live polls.
