Privacy-first unofficial Polar AccessLink v4 MCP server for AI health, sleep and training agents.
Privacy-first unofficial Polar AccessLink v4 MCP server for AI health, sleep and training agents.
Polar MCP is a well-structured local-first wellness connector with proper OAuth token handling, clear privacy boundaries, and read-mostly operations. The code demonstrates good security practices for credential storage (env vars, local files with restrictive permissions, no hardcoded secrets). Minor code quality observations exist around error handling and input validation, but they do not introduce exploitable vulnerabilities. Permissions align with the server's purpose of reading wellness data from the Polar API. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue (1 critical, 0 high severity).
