## Description
Privacy-first, unofficial Withings MCP server for AI health, sleep, activity and heart-rate agents.

## Tools
Capabilities this server exposes over MCP:

- **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
- **withings_list_body_measures** — punctual weight/composition records. Use `after` / `before` as `YYYY-MM-DD` or ISO 8601 for large histories; the server sends Withings `startdate` / `enddate` (Unix seconds) upstream and caps returned records with `limit`.
- **withings_list_heart** — heart records when device/plan permit
- **withings_list_activity** — daily activity summaries
- **withings_list_workouts** — logged workouts
- **withings_list_sleep_summary** — daily sleep summaries with HR/stage fields
- **withings_list_sleep** — detailed sleep records

## HTTP (v2 stateless)

Default is **stdio**. Optional Streamable HTTP — no session id, JSON responses, loopback only:

```bash
npx -y withings-mcp-unofficial --http
# GET  http://127.0.0.1:3000/health
# POST http://127.0.0.1:3000/mcp   (sessionless)
```

Env: `WITHINGS_MCP_HOST`, `WITHINGS_MCP_PORT`, `WITHINGS_MCP_TRANSPORT=http`.


<!-- /delx-wellness header v2 -->

**Local-first MCP server that connects AI agents to your Withings body, sleep, activity and heart data.**

> **Unofficial project.** Not affiliated with, endorsed by or supported by Withings. 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 `after` / `before` as `YYYY-MM-DD` or ISO 8601 for large histories; the server sends Withings `startdate` / `enddate` (Unix seconds) upstream and caps returned records with `limit`.
- Date filters are action-aware: `getactivity` / `getworkouts` / sleep `getsummary` send civil `startdateymd` / `enddateymd`; `getmeas`, sleep detail, and heart list keep epoch `startdate` / `enddate`. Offset ISO instants keep their exact epoch conversion on epoch-style actions.
- `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.
- Structured mode preserves complete upstream physiological fields, including future Withings additions, while removing GPS and secret-bearing values.
- `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

## Skill or MCP

Same package, two doors. MCP registers tools on stdio/HTTP. The [skill](https://github.com/davidmosiah/withingsmcp/blob/HEAD/skill/SKILL.md) can drive the **same** tools through the CLI when the client has no MCP:

```bash
npx -y withings-mcp-unofficial call withings_connection_status --json '{}'
```

Copy `skill/SKILL.md` into your agent skills dir.
