Polarmcp

Overview

Polarmcp is a privacy-first MCP server that connects AI health, sleep and training agents to Polar's AccessLink v4 API. Running locally on your machine, it exposes Polar fitness and health data as tools that Claude, Cursor, VS Code and other MCP clients can use directly, keeping your data under your control.

The server is installed via npx -y polar-mcp-unofficial and requires a Polar API key to authenticate. It's built on the polar-mcp-unofficial npm package, published under the MIT license with source code available at davidmosiah/polar-mcp on GitHub. The latest release is v0.3.6.

Polarmcp belongs in the AI & Agents category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this project, claim the listing to verify ownership and keep the information accurate.
