Use Forkmate in Grok
Grok can add a remote MCP server as a custom connector. Add Forkmate once and Grok can keep your food diary.
https://mcp.forkmate.ai/Then paste it into Grok (steps below). No API key: you sign in once. Open grok.com/connectors
No Forkmate account yet? Create one free first. It takes under a minute, and Grok sends you there on first connect anyway.
I had two eggs and toast for breakfast.
Logged. Want me to total today so far?
Set up Forkmate in Grok
- Open ConnectorsGo to grok.com/connectors.
- Add a custom connectorClick New Connector, choose Custom, and enter
https://mcp.forkmate.ai/. - Sign in to Forkmate onceGrok opens a Forkmate sign-in in your browser. Sign in (or create your free account) and approve access. That one-time OAuth step connects it to your diary and nobody else’s.
- Give your OK onceThe first time you log, Forkmate asks once for your OK to store your food diary. Agree the way it asks, in the chat or through the link it gives you to agree on the web, then log the meal again if it wasn’t saved.
- Log your first mealIn Grok, say “I had two eggs and toast for breakfast.” It logs the meal with calories and macros to your Forkmate diary.
What you need
- A free Forkmate account (sign up). There is no paid plan.
- On Grok Business and Enterprise, a team admin adds the connector first (+ Add Connector → Other), then you connect.
- xAI says connectors are available to all Grok users. Its docs don’t say whether custom connectors work in the mobile apps, and we haven’t confirmed it.
Checked against these sources: xAI: connectors, xAI: connector management. Grok changes its menus often; if yours looks different, trust what it shows.
What to say first
Talk to Grok the way you’d tell a friend:
- “I had two eggs and toast for breakfast.”
- “How many calories have I had today?”
- “Make the toast two slices.”
- “What did I eat this week?”
It logs the meal with calories, protein, carbs and fat to your diary at app.forkmate.ai.
Good to know in Grok
- xAI says connectors are available to all Grok users.
- Grok finds Forkmate’s tools on its own once connected; xAI documents no per-chat switch.
Checked against xAI: connectors.
Forkmate shortcuts
Forkmate comes with ready-made requests for the everyday jobs: log a meal, fix the last entry, see what’s left today, log your usual, hit your protein, a weekly check-in. We haven’t found MCP shortcuts (prompts) in Grok’s menus or documentation, so type or paste the request instead.
- Log a meal (log-meal)
“Log this to my Forkmate diary: two eggs and toast with butter” - Fix my last entry (fix-last-entry)
“Fix the last thing I logged in Forkmate: it was 2 eggs, not 3” - What's left today (today-so-far)
“Show me today so far in Forkmate: my calories, protein, carbs and fat.” - Log my usual (log-my-usual)
“Log my usual breakfast to Forkmate.” - Hit my protein today (hit-protein)
“How much protein have I had today in Forkmate, and how far am I from my target of 120 g? Suggest a few foods for my remaining meals and snacks that would close the gap, using my food profile and the foods I usually eat.” - Weekly check-in (week-review)
“Give me a check-in on my last 7 days in Forkmate (get_range): calories, protein, carbs and fat per day and on average, how many days I logged, and the foods I ate most.” - Move my MyFitnessPal history (import-myfitnesspal)
“How do I move my food diary history from MyFitnessPal to Forkmate? Walk me through exporting my data for free and importing it with the guided importer described at https://forkmate.ai/migrate-from-myfitnesspal/. Don't log anything yet.”
Shortcut or not, Forkmate sends Grok the same logging rules when it connects: log your own words, keep your amounts, and look foods up before estimating.
