Safety And Privacy#

• Fitbit OAuth tokens stay under ~/.fitbit-mcp/ by default. Be explicit about Google/Fitbit platform migration risk.
• 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 Fitbit MCP for Claude Desktop without exposing secrets.
• Run the manifest, connection status, and privacy audit for Fitbit MCP.
• Explain what user data Fitbit MCP can expose and what should remain opt-in.
