如何將Fitbit連線到Claude

No. Fitbit ships no Model Context Protocol server of its own, so Claude cannot read Fitbit data directly. Wellness Project connects to Fitbit over OAuth, holds your synced history, and exposes it to Claude over a single MCP server. That hosted server is the working path today, not a community repo you self-host.

MCP is the Model Context Protocol, an open standard from Anthropic that lets Claude connect to an outside data source through a consistent interface. Think of it as a standard plug: instead of pasting data into the chat, you point Claude at a server that already holds your Fitbit history and it reads the specific rows it needs, when it needs them.

Whatever Fitbit syncs into Wellness Project: steps, Active Zone Minutes, sleep stages, and resting heart rate. Claude reads structured, interpreted rows rather than a raw export, so you can ask about trends and baselines across weeks. Access is read-only, so Claude cannot write to or change your data over MCP.

Two OAuth grants are involved and both are yours to revoke. Fitbit access is approved when you connect it. Claude access is approved when you add the Wellness Project connector. Revoke either grant and that service loses access.

Yes. The same synced Fitbit history is served over one MCP server, so ChatGPT reads it as a plugin the same way Claude reads it through its connector. If ChatGPT is your main assistant, follow the Fitbit to ChatGPT guide; the Fitbit sync step is identical.
