What is the Yazio MCP server?

Connect Yazio to Claude, Cursor or any other MCP client and it stops being a tab you switch to. MCP server for accessing Yazio user & nutrition data (unofficial). The yazio mcp server is what makes that connection.

What the server does

An MCP (Model Context Protocol) server that connects Claude/Cursor to your Yazio nutrition data. Track your diet, search food products, and manage your nutrition goals directly from your AI assistant.

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • get_user_daily_summary — Get daily nutrition summary
  • get_user_consumed_items — Get food entries for a date
  • get_user_weight — Get weight data
  • get_user_exercises — Get exercise data
  • get_user_water_intake — Get water intake
  • get_user_goals — Get nutrition goals
  • get_user_settings — Get user preferences
  • search_products — Search food database
  • get_product — Get detailed product info
  • add_user_consumed_item — Add food to your log
  • add_user_water_intake — Add water intake entry (cumulative value in ml)
  • remove_user_consumed_item — Remove food from log

Installation

yazio-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Credentials and setup notes

Configuration is passed through the environment: YAZIO_USERNAME, YAZIO_PASSWORD. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Where it fits

Among the database access options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Yazio's toolset — get_user_daily_summary, get_user_consumed_items, get_user_weight and 10 more — is a fair guide to whether it matches your workflow. It is maintained by fliptheweb; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 13 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Yazio.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
