Two paths: direct and bridged
Here is the honest map. A few services connect to Wellness Project directly, through their own API, so their data flows in on its own. Everything else does not have a direct link, and there is no per-device MCP server for them. If your device is not on the supported list, that is not a dead end, it is just the other path.
That other path is the bridge. Nearly every fitness device already writes to a health hub: Apple Health on iPhone, Google Health Connect on Android. Your device syncs there anyway. Wellness Project reads that hub, structures the raw entries into a clean history, and serves it to Claude and ChatGPT over one MCP connection. The bridged path is Device to Apple Health or Health Connect to Wellness Project to Claude or ChatGPT. Same destination as the direct path, one extra relay.
The general relay, step by step
If your device is not directly supported, this is the whole procedure. It works the same no matter which device you carry, because the hub does the heavy lifting.
Your device already writes to your phone’s health hub
Open your device’s own app (Garmin Connect, the Whoop app, Withings Health Mate, and so on) and turn on its sync to Apple Health on iPhone or Google Health Connect on Android. Grant the categories you want shared, such as steps, workouts, heart rate, and sleep. This is the intermediary that stands in for a direct connection.
Wellness Project reads that hub
Connect Apple Health (iPhone) or Health Connect (Android) to Wellness Project and grant read permission. Whatever your device deposits in the hub gets pulled into your Wellness Project history and structured into metrics you can actually query, alongside anything you connected directly.
Add the MCP connector to Claude or ChatGPT
Add the Wellness Project connector to Claude through the Model Context Protocol, or enable the plugin in ChatGPT. You do this once. Neither assistant touches your device directly; they read the structured history that arrived through the hub.
Ask across your data
Ask questions that span everything at once. How did my training and sleep move together this month? Is my resting heart rate drifting? Did the heavier weeks cost me recovery? Claude or ChatGPT reads your unified history against your own baseline and answers in plain language.
If the device app is not writing to the hub, nothing reaches your history. That first sync is the foundation for every bridged device, so confirm it before anything else.
Bridge devices we cover in detail
These devices do not connect directly, but they all relay cleanly through Apple Health or Health Connect. Each guide walks the exact toggle for that device and what crosses the hub: Garmin, Whoop, Withings, Strava, Peloton, Polar, Coros, Amazfit, and Wahoo.
The pattern is identical across all of them: turn on the device app's sync to the hub, connect the hub to Wellness Project, add the connector to Claude or ChatGPT. What differs is only which categories each device writes and whether any of its branded composite scores stay inside its own ecosystem instead of crossing the hub. The per-device guide says so plainly.
How this differs from our other device guides
If your device already connects directly, you do not need the relay at all, and the wearable guide covers those supported devices and how they read as one history. The all-devices page is the plain roster of what Wellness Project connects. This page is the one for the awkward middle: your device is not on the list, and you still want it in.
Direct or bridged, the destination is the same structured layer that Claude and ChatGPT read. The relay just makes sure a device without a direct connection is not left out of the picture.
