Nutria MCP server

Nutria works with AI assistants such as Claude and ChatGPT through the Model Context Protocol (MCP). Once connected, you can tell your assistant what you ate or send it a photo of your meal, and ask about your diary, nutrition plan and progress.

Connecting

Add a custom connector in your assistant with this URL:

https://mcp.nutria-app.com/mcp

In Claude Code: claude mcp add --transport http nutria https://mcp.nutria-app.com/mcp

You'll be asked to sign in with your Nutria account and allow access. The assistant only sees and changes your own data, using the same dates and timezone as the Nutria app.

Tools

Food diary

  • log_meal_from_ingredients (saves data) — Logs a meal from a list of ingredients with weights, including from a photo of your plate or a food label. Nutria calculates calories, macros and micronutrients, rates the meal and returns your totals for the day.

  • delete_meal_record (saves data) — Deletes a meal logged by mistake.
  • day_meals — Meals logged on a given day, with ingredients and macros.
  • meals_by_dates — Meals for every day in a range of up to 30 days.
  • meal_details — One meal in full: ingredients, micronutrients, rating out of 10 and feedback on how to make it better.

Nutrition

  • my_nutrition_plan — Your daily calorie, macro, water and micronutrient targets, goals, diet and supplements.
  • food_nutrients — Looks up calories, macros and micronutrients of foods without logging them. Works without signing in.
  • day_micronutrients — Vitamins, minerals and other nutrients eaten on a day against your targets.
