什么是 MCP，以及它如何让 Claude 读取你的 Apple Health 数据

MCP is the Model Context Protocol, an open standard from Anthropic that lets an AI like Claude connect to outside data sources and tools through a consistent interface. Think of it as a standard plug: instead of every app inventing its own way to feed Claude information, a service runs an MCP server and Claude reads from it the same way it reads from any other connector. Wellness Project runs one of these servers over your synced health history.

Claude does not get a copy of your whole record. Through MCP it requests specific rows during an active conversation, and only those rows travel. Access is gated by an OAuth grant you can revoke from your account settings.

Claude can read the synced history Wellness Project holds: steps, sleep duration and stages, workouts, resting heart rate, HRV, body metrics, and labs you have logged. It reads structured, interpreted rows rather than a raw export, so you can ask about trends and baselines, not just a single day. It cannot write to your record or change your data through MCP.

Yes. The MCP server reads whatever you have connected to Wellness Project, so Fitbit, Oura, and Android Health Connect feed the same history Apple Health does. Connect any combination and Claude reads across all of them at once. There is a dedicated Fitbit MCP path if Fitbit is your main device.
