Safety And Privacy

• Polar OAuth tokens stay under ~/.polar-mcp/. Route/GPS data should remain opt-in.
• Do not print OAuth tokens, API keys, service-account JSON, local token files, or private user data.
• Prefer connection_status, manifest, doctor, privacy_audit, or dry-run surfaces before any write or live provider call.
• These tools are not medical, legal, financial, or platform-policy advice. Keep user consent explicit.

Example Prompts

• Install and verify Polar MCP for Claude Desktop without exposing secrets.
• Run the manifest, connection status, and privacy audit for Polar MCP.
• Explain what user data Polar MCP can expose and what should remain opt-in.
