What it can do
- Read. A daily brief scored against your own normal, your baselines, what changed this week, any metric day by day, workouts, lifts set by set, sleep stages and your food diary.
- Log. Your AI logs meals, water, weight, workouts, sleep, symptoms and mood when you ask, after you turn on Allow AI write for that way in Marrow. Every entry can be undone.
Try asking
- How am I doing today?
- What changed in my sleep this week compared with my normal?
- Which of my lifts went up this month?
- Log a turkey sandwich and an apple for lunch.
If it does not work
In Grafana Assistant
- No MCP servers tab. An administrator must enable the integrations feature in the Assistant app configuration. Editors can add servers for themselves.
- A Local MCP address is refused. Grafana Assistant takes remote servers only, so it needs the Cloud MCP link.
- Authentication errors (401 or 403). Make sure pop-ups are not blocked for the sign-in, then approve the code in Marrow.
- Check it. Click Test connection on the server. It checks your access and refreshes the tool list.
Cloud MCP checks
- The sign-in waits in Marrow. The sign-in page shows a 6-character code. Open Marrow, go to Export, type the code and tap Approve. A request expires after ten minutes and three wrong codes deny it. If that happens, start again from your AI.
- The page says the link did not match a Marrow. In Marrow, open your AI under Connections, tap Copy your link and paste the whole link.
- It worked, then stopped. When Cloud MCP is off, or Marrow Pro has ended, the copy is paused. Switching Cloud MCP off also signs every AI out. Turn it back on, switch this connection on in Your connections and sign in again from your AI.
- Approve stops at the limit. Each AI is one connection. Free keeps 1 connection on at a time. Marrow Pro keeps up to 10: AIs, servers and automations together. Turn one off in Your connections, then approve again.
- It reads but cannot log. Turn on Allow AI write for Cloud MCP in Marrow. An entry reaches the phone within seconds when notifications are allowed for Marrow, or the next time you open the app.
