Google Health Mcp

davidmosiah/google-health-mcp

Unofficial local-first server for Google's new Health API v4, which consolidates Fitbit, Pixel Watch, and partner health data under a single OAuth flow. Exposes read-only tools for identity, profile, settings, data point queries, reconciliation, and daily/weekly rollups across steps, sleep, heart rate, nutrition, and activity domains. The beta ships with a standalone doctor command for setup validation and scope presets that keep consent screens manageable. Tokens never leave your machine. Useful if you're building health agents that need to query reconciled streams from Google's ecosystem without pasting credentials into prompts. Author warns that Google may ship breaking changes before the official v4 launch in May 2026.
