Withings is a trademark of its respective owner. Use this only with your own Withings account and in line with the Withings Public API terms. Built by [David Mosiah](https://github.com/davidmosiah) for people who use Claude, Cursor, Hermes, OpenClaw or other MCP-compatible agents to think about body composition, sleep and long-term health trends — without copy-pasting numbers from the Withings app. Part of [Delx Wellness](https://github.com/davidmosiah/delx-wellness), a registry of local-first wellness MCP connectors. > If this connector helps your agent workflow, please star the repo. Stars make the project easier for other AI builders to discover and help Delx keep shipping local-first wellness infrastructure. ## Why this exists Withings has the longest-running consumer body-composition and sleep ecosystem (smart scales, Sleep Analyzer, ScanWatch). The data is rich — punctual weight + body fat + muscle mass measurements, sleep stages, ECG-grade heart records — but the Withings Public API uses a signed-token OAuth flow that's heavier than most consumer APIs. This package handles the signed OAuth dance locally, normalizes responses, and exposes Withings through the Model Context Protocol. Tokens never leave your machine. Privacy-mode defaults keep raw payloads opt-in. ## Setup in 60 seconds You'll need a Withings app ([create one here](https://account.withings.com/partner/dashboard_oauth2)) with redirect URI `http://127.0.0.1:3000/callback`. ```bash npx -y withings-mcp-unofficial setup # interactive: paste client id + secret npx -y withings-mcp-unofficial auth # opens browser, captures the OAuth code npx -y withings-mcp-unofficial doctor # verifies you're ready ``` Recommended scopes: ```text user.activity user.metrics ``` Then add this to your MCP client config: ```json { "mcpServers": { "withings": { "command": "npx", "args": ["-y", "withings-mcp-unofficial"] } } } ``` For Claude Desktop, run `setup --client claude` and the snippet is written for you. > **Note:** Withings OAuth authorization codes are short-lived (a few minutes). Don't pause between approving the consent screen and `withings_exchange_code` running. ## Try it with your agent Three things to ask first: ```text Use withings_connection_status to check setup, then run withings_daily_summary. Give me a 5-line wellness brief for today. ``` ```text Call withings_weekly_summary with response_format=json. Identify my biggest sleep/body bottleneck and give me a next-week plan. ``` ```text Use the withings_body_sleep_investigation prompt, after=2026-04-01. Walk me through what changed in body composition + sleep. ``` ## Data availability This package uses the official Withings Public API. When this README says `raw`, it means the upstream Withings JSON for a supported endpoint — not raw device sensor streams. | Data | Available | Notes | |---|:---:|---| | Body measures (weight, fat %, muscle, bone, water) | ✓ | Requires `user.metrics` scope | | Daily activity (steps, calories, distance, intensity) | ✓ | Requires `user.activity` scope | | Workouts + sport metadata | ✓ | Requires `user.activity` scope | | Sleep summaries (duration, stages, efficiency, HR) | ✓ | Requires `user.activity` scope | | Sleep detail records | ✓ | When the device exposes them | | Heart records (ECG, BP, etc.) | ✓ | Requires `user.metrics` scope; varies by device/plan | | Continuous sensor telemetry | — | Not exposed by Withings Public API | ## Tools **Start with these:** - `withings_connection_status` — verify local setup before calling Withings - `withings_data_inventory` — inventory supported data domains, scopes, privacy modes and recommended first calls without calling Withings APIs. - `withings_daily_summary` — body, sleep, activity and heart brief for today - `withings_weekly_summary` — scorecard, comparison vs prior week, next-week plan **Auth & diagnostics** - `withings_capabilities`, `withings_agent_manifest`, `withings_privacy_audit`, `withings_cache_status` - `withings_get_auth_url`, `withings_exchange_code`, `withings_revoke_access` **Body & metrics** - `withings_list_body_measures` — punctual weight/composition records. Use ISO 8601 `after` / `before` windows for large histories; the server sends Withings `startdate` / `enddate` upstream and caps returned records with `limit`. - `withings_list_heart` — heart records when device/plan permit **Activity** - `withings_list_activity` — daily activity summaries - `withings_list_workouts` — logged workouts **Sleep** - `withings_list_sleep_summary` — daily sleep summaries with HR/stage fields - `withings_list_sleep` — detailed sleep records ## Prompts - `withings_daily_checkin` — practical daily health and body check-in - `withings_weekly_review` — review trends across body, sleep, activity - `withings_body_sleep_investigation` — investigate body measures + sleep together ## Resources - `withings://capabilities`, `withings://agent-manifest` - `withings://latest/activity`, `withings://latest/sleep` - `withings://summary/daily`, `withings://summary/weekly` ## Privacy & security - OAuth tokens are stored in `~/.withings-mcp/tokens.json` with `0600` permissions and are never returned by tools. - Withings uses a signed-request OAuth flow — the package handles signing locally; client secrets never reach the MCP client. - The server never prints access or refresh tokens. - `WITHINGS_PRIVACY_MODE` defaults to `structured`. Raw Withings JSON is opt-in via `raw` mode or per-call override. - `withings_revoke_access` clears local tokens; full account-side token revocation depends on your Withings plan. - The MCP client never sees access or refresh tokens. - This is **not medical advice**. Withings exposes data that may resemble medical signals (ECG, blood pressure) but this server is for personal AI workflows, not diagnosis or treatment. ## Configuration `setup` writes most of these into `~/.withings-mcp/config.json` (`0600`). Manual env override is supported: ```bash WITHINGS_CLIENT_ID=… WITHINGS_CLIENT_SECRET=… WITHINGS_REDIRECT_URI=http://127.0.0.1:3000/callback # Optional WITHINGS_SCOPES="user.activity user.metrics" WITHINGS_PRIVACY_MODE=structured # summary | structured | raw WITHINGS_CACHE=sqlite # optional read-through cache WITHINGS_TOKEN_PATH=~/.withings-mcp/tokens.json WITHINGS_CACHE_PATH=~/.withings-mcp/cache.sqlite ``` ## Hermes / remote setup ```bash npx -y withings-mcp-unofficial setup --client hermes --no-auth npx -y withings-mcp-unofficial auth # run locally if browser auth is needed npx -y withings-mcp-unofficial doctor --client hermes hermes mcp test withings ``` After Hermes config changes, use `/reload-mcp` or `hermes mcp test withings`. Don't restart the gateway for normal data access. If browser OAuth has to happen on a different machine than Hermes, run `auth` locally and copy `~/.withings-mcp/tokens.json` to the server with `chmod 600`. ## Requirements - Node.js 20+ - A Withings app at <https://account.withings.com/partner/dashboard_oauth2> with redirect URI `http://127.0.0.1:3000/callback` ## Development ```bash git clone https://github.com/davidmosiah/withings-mcp.git cd withings-mcp npm install npm test npm run build ``` Test with MCP Inspector: ```bash npx @modelcontextprotocol/inspector node dist/index.js ``` ## Links - npm: <https://www.npmjs.com/package/withings-mcp-unofficial> - Docs site: <https://wellness.delx.ai/connectors/withings> - Legacy docs: <https://withingsmcp.vercel.app/> - GitHub: <https://github.com/davidmosiah/withings-mcp> - Delx Wellness registry: <https://github.com/davidmosiah/delx-wellness> - Connector quality standard: <https://github.com/davidmosiah/delx-wellness/blob/main/docs/connector-quality-standard.md> - Withings Public API docs: <https://developer.withings.com/api-reference/> <!-- delx-wellness see-also --> ## See also The full [Delx Wellness](https://wellness.delx.ai) connector library: | Provider | Package | Repo | |---|---|---| | WHOOP | [`whoop-mcp-unofficial`](https://www.npmjs.com/package/whoop-mcp-unofficial) | [whoop-mcp](https://github.com/davidmosiah/whoop-mcp) | | Oura | [`oura-mcp-unofficial`](https://www.npmjs.com/package/oura-mcp-unofficial) | [ouramcp](https://github.com/davidmosiah/ouramcp) | | Garmin | [`garmin-mcp-unofficial`](https://www.npmjs.com/package/garmin-mcp-unofficial) | [garminmcp](https://github.com/davidmosiah/garminmcp) | | Strava | [`strava-mcp-unofficial`](https://www.npmjs.com/package/strava-mcp-unofficial) | [strava-mcp](https://github.com/davidmosiah/strava-mcp) | | Fitbit | [`fitbit-mcp-unofficial`](https://www.npmjs.com/package/fitbit-mcp-unofficial) | [fitbitmcp](https://github.com/davidmosiah/fitbitmcp) | | Withings | [`withings-mcp-unofficial`](https://www.npmjs.com/package/withings-mcp-unofficial) | [withings-mcp](https://github.com/davidmosiah/withings-mcp) | | Apple Health | [`apple-health-mcp-unofficial`](https://www.npmjs.com/package/apple-health-mcp-unofficial) | [apple-health-mcp](https://github.com/davidmosiah/apple-health-mcp) | | Polar | [`polar-mcp-unofficial`](https://www.npmjs.com/package/polar-mcp-unofficial) | [polarmcp](https://github.com/davidmosiah/polarmcp) | | Nourish (nutrition) | [`wellness-nourish`](https://www.npmjs.com/package/wellness-nourish) | [wellness-nourish](https://github.com/davidmosiah/wellness-nourish) | **One-command setup for Hermes** — preconfigures every connector above plus wellness skills + onboarding: [`delx-wellness-hermes`](https://github.com/davidmosiah/delx-wellness-hermes). <!-- /delx-wellness see-also --> ## 📧 Contact & Support - 📨 **support@delx.ai** — general questions, integration help, partnerships - 🐛 **Bug reports / feature requests** — [GitHub Issues](https://github.com/davidmosiah/withings-mcp/issues) - 🐦 **Updates** — [@delx369](https://x.com/delx369) on X - 🌐 **Site** — [wellness.delx.ai](https://wellness.delx.ai) ## License MIT — see [LICENSE](LICENSE). ## Disclaimer This software is provided as-is.
