Grok
Connect Grok to your fitness tracker and log it all by chat.
Wellness Project connects to Grok, the AI assistant from xAI, as a custom MCP connector. Tell Grok what you ate, how you trained, or how you slept, and it lands structured in the right tracker — then Grok reads your trends back when you ask. It’s the same OAuth-protected MCP server Claude and ChatGPT use, and Grok registers itself, so there’s no API key or Client ID to paste.

What's inside
Grok as the front-end for logging and tracking your health
Log meals from Grok
"Log lunch: chicken burrito bowl, rice, and guac." Grok hands it to Wellness Project, which estimates the calories and macros and files it in your nutrition log — no label-scanning, no forms.
Log workouts from Grok
"Log my push day: bench 4x6 at 195, OHP 4x8 at 115." Grok structures the sets and reps; Wellness Project saves the session and detects PRs.
Log sleep, weight, and more
Most modules Wellness Project tracks are callable from Grok — sleep, body weight, supplements, recovery, wellbeing, runs, lab results.
Read your data in Grok
Ask "how did training look this week?" or "is my HRV up?" and Grok queries Wellness Project for the real figures — and can draw the answer as a live inline chart (Fit Score, training, sleep, steps, recovery, runs, weight, or lift progression) instead of a wall of text.
Grok registers itself — no key, no Client ID
Unlike a Claude API key or Le Chat's required Client ID, Grok self-registers over OAuth. Paste the URL, sign in, done.
No tunneling, no hosting
The server is publicly reachable at wellnessproject.ai/api/mcp, so — unlike a local MCP server — there is nothing to expose with ngrok or a Cloudflare Tunnel.
Step by step
Connect Grok in four steps
- 1Open Grok’s Connectors page
In grok.com, go to Settings → Connectors (or grok.com/connectors), click New Connector, then choose Custom. Custom connectors are part of Grok’s Connectors feature and may require a paid Grok plan.
- 2Paste the MCP server URL
Enter wellnessproject.ai/api/mcp and leave Client ID and Client Secret blank — Grok registers itself automatically.
- 3Sign in to authorize
A Wellness Project sign-in window opens over OAuth. Sign in with the same account you use in the app and approve; Grok then loads the tool list.
- 4Just start talking
In any Grok chat, say things like "log my workout" or "what did I eat yesterday?" Grok picks the right tool on its own.
In the app
Most Grok fitness advice tells you to prompt it. This lets you keep the data.
There’s a lot of interest in using Grok for nutrition and training — asking it to generate a meal plan or a workout. That’s generating, not tracking. Nothing persists. Wellness Project is the missing half: connect it once and every meal, set, and night of sleep you mention to Grok is logged and kept, so it compounds into trends instead of scrolling out of the chat.
The connection is a two-way MCP link. Grok writes to your tracker when you log, and reads from it when you ask — “did my running volume go up last week?” pulls your real weekly mileage and compares it to the prior week. It’s the same /api/mcp endpoint and the same tool set Claude and ChatGPT reach, so your data layer is identical no matter which assistant you prefer.
The in-app walkthrough with screenshots is at Settings → Grok. If you’d rather use a different assistant, the same server works with Claude, ChatGPT, and Mistral Le Chat.
