How the relay actually works
Let us be straight about it: there is no direct Whoop connection to Wellness Project, and there is no Whoop MCP server to add anywhere. Whoop does not ship an AI integration of its own either, so if you came looking for a switch that wires your strap straight into an assistant, that switch does not exist.
What does exist is the hub your Whoop already syncs to. On iPhone, the Whoop app can write to Apple Health. On Android, it writes to Google Health Connect. That is where your recovery, strain, sleep, and heart-rate data can already collect. Wellness Project reads that hub, structures the raw entries into a clean recovery history, and serves it to Claude and ChatGPT over a single MCP connection. The full path is Whoop to Apple Health or Health Connect to Wellness Project to Claude or ChatGPT.
Turn on the Whoop to health-hub sync first
The relay only works once the Whoop app is actually writing to your phone's health hub. This is a Whoop setting, not a Wellness Project one, and it takes about a minute.
Your Whoop already writes to your phone’s health hub
On iPhone, open the Whoop app, find the Apple Health or integrations setting, and enable it, granting the categories you want shared: heart rate, heart-rate variability, sleep, and workouts. On Android, grant the Whoop app permission to write to Google Health Connect. This is the intermediary. Whoop keeps syncing your strap as it always has, and now it also deposits that data into the hub.
Wellness Project reads that hub
Connect Apple Health (iPhone) or Health Connect (Android) to Wellness Project and grant read permission. From then on, whatever Whoop writes into the hub gets pulled into your Wellness Project history and structured into recovery, sleep, HRV, and heart rate you can actually query.
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 ever touches Whoop directly; they read the structured history that arrived through the health hub.
Ask across your data
Now ask real questions. Is my recovery trending down this week? Did last night’s short sleep drop my HRV the next morning? Am I stacking hard days without letting resting heart rate settle? Claude or ChatGPT reads your Whoop-sourced history against your own baseline and answers in plain language.
If the Whoop app is not writing to the hub, nothing reaches your history. That first toggle is the whole foundation, so confirm it before anything else.
A note on platforms and what crosses cleanly
On iOS the bridge is Apple Health; on Android it is Health Connect. The raw signals Whoop records tend to cross cleanly: heart rate, heart-rate variability, sleep stages and duration, and workouts. Whoop's branded composite scores, its recovery percentage and strain number, are computed inside Whoop's own model and may not write to the hub as standalone values. The inputs that produce them usually do, so an AI can reconstruct the recovery picture from HRV, resting heart rate, and sleep even when the single percentage is not present.
One naming caveat worth knowing: HRV can appear under a generic heart-rate-variability label in the hub rather than Whoop's own wording. If a metric you expect is missing, it usually means Whoop did not write that category to the hub, not that Wellness Project dropped it.
Why route through the hub at all
It is fair to ask why not just read the Whoop app. The Whoop app is great at showing Whoop's own scores. What it cannot do is let an AI read across your recovery and compare it to everything else you track. The health hub is the neutral ground where Whoop's signals meet the rest of your data, and Wellness Project is the layer that turns that pile into something Claude or ChatGPT can reason about.
You keep wearing your Whoop, keep using the Whoop app, and change nothing about your routine. The relay simply gives your recovery data a second home where an AI coach can finally use it.
