FAQ from Withings Mcp Unofficial

What data domains does Withings Mcp Unofficial support?

Body measures (weight, fat %, muscle, bone, water), daily activity (steps, calories, distance), workouts, sleep summaries and details, and heart records (ECG, BP, etc.) when device/plan allow. Continuous sensor telemetry is not exposed by the Withings Public API.

What are the runtime requirements?

Node.js 20+ and a Withings app registered at the Withings partner dashboard with redirect URI http://127.0.0.1:3000/callback. Scopes user.activity user.metrics are recommended.

Where are OAuth tokens stored?

Tokens are stored in ~/.withings-mcp/tokens.json with 0600 permissions and are never returned by tools. The server never prints access or refresh tokens.

How does authentication work?

The package handles the signed‑request OAuth flow locally; client secrets never reach the MCP client. The OAuth code is short‑lived (a few minutes). After authorizing, the token is exchanged and stored.

Is this project affiliated with Withings?

No. This is an unofficial project, not affiliated with, endorsed by, or supported by Withings. Use it only with your own Withings account and in line with the Withings Public API terms.
