Your setup screen may look different.
AI assistants change their settings and navigation frequently. Menu names and steps can vary by web, desktop, or mobile client, device and operating system, plan, account type, version, and staged rollout. Treat the instructions on this page as a current guide and look for the equivalent Apps, Connectors, Plugins, or MCP controls if your version differs.
What's inside
Le Chat as the front-end for your whole health log
Log meals from Le Chat
"Log breakfast: eggs, toast, a banana smoothie." Le Chat passes it to Wellness Project, which fills in the calories and macros for you — describe the plate in a sentence and it's tracked.
Log workouts and runs
"Log my run: 5k in 26:40, easy." Le Chat structures it; Wellness Project saves pace, distance, and heart rate, and detects PRs on lifts.
Not just endurance — log everything
Meals, sleep, body weight, supplements, recovery, wellbeing, and lab results are all callable. Le Chat becomes a general health log, not only a training tracker.
Read your data in Le Chat
Le Chat reads as well as writes: ask about last week's volume, your weight trend, or how you slept, and it pulls the actual figures — optionally as a live chart you can flip between 7-day, 30-day, and 90-day views.
EU-hosted assistant, first-party data
Mistral is a European company; pairing Le Chat with a tracker that keeps your health data in your own account is a clean fit for privacy-minded users.
OAuth setup that follows Le Chat
Le Chat registers its OAuth client when you add the connector, using the callback it is using now instead of a shared Client ID that can go stale.
Step by step
Connect Le Chat in five steps
- 1Open the Connectors panel
In Le Chat, open the panel under Intelligence → Connectors → Add Connector → Custom MCP Connector. Give it a name like "Wellness Project." Adding a connector is an admin action; on Free, Pro, and Student plans the account owner is the admin.
- 2Paste the Server URL
Enter wellnessproject.ai/api/mcp. Le Chat detects the server and selects OAuth 2.1 automatically — give it a moment on "Detecting…".
- 3Let it register itself
Leave Client ID and Client Secret empty. Le Chat registers automatically from the server's OAuth metadata, then continues to the Wellness Project sign-in.
- 4Sign in to authorize
Make sure you are signed in to wellnessproject.ai in the same browser, then approve the connection. Once it authorizes, the Create button enables — click it to finish.
- 5Just start talking
In any Le Chat conversation, say things like "log my workout" or "how did I sleep this week?" Le Chat calls the right tool on its own.
In the app
One server URL, no shared OAuth ID
Le Chat now registers the connector dynamically. That keeps the OAuth client tied to Le Chat's current callback, while your Wellness Project account is still protected by the normal sign-in, consent, and PKCE flow.
The other fitness tools that connect to Le Chat are endurance-only — runs, rides, and training load. Wellness Project is the general-health option: log a meal, a night of sleep, your weight, or your wellbeing just as easily as a workout, and ask Le Chat about any of it later. One /api/mcp endpoint, the same tool set Claude and ChatGPT reach.
The in-app walkthrough with screenshots is at Settings → Mistral. The same server also works with Claude, ChatGPT, and Grok.
