Withings MCP server

This is a small helper that connects your AI assistant to your Withings account. Once it is set up, you can ask plain questions about your weight, sleep, workouts and heart readings, and your AI will look them up for you. It is handy if you use a Withings scale, watch or sleep tracker and want to see how things change over weeks and months.

What this MCP server does

You ask your AI something like how your weight changed this year. The AI sends that request to this helper. The helper keeps a copy of your Withings data in a small local file on your computer, so it can answer quickly without asking Withings every time. When the copy is out of date, it quietly fetches just the new data. Then it hands back a summary, a list of numbers or a trend, and your AI explains it to you.

Try asking your AI

• “Sync my Withings data”
• “Show my weight for the last 3 months”
• “How has my sleep changed this year?”
• “Compare my body composition this month vs last month”
• “What workouts did I do in March?”

What it gives back to you

You get answers in the chat: lists of readings, short summaries, averages and trends. For example, it might say your average weight dropped a little over three months, or that your sleep was longer on weekends. If you ask for detail, it can show night-by-night sleep phases or a list of workouts. It never changes anything in your Withings account.
