Yazio MCP Server

[!IMPORTANT] This is not an official MCP server and Yazio does not provide an official API. This server uses an unofficial reverse-engineered API and may stop working at any time.

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 on NPM: npx yazio-mcp

Claude Desktop Extension: yazio-mcp.mcpb — one-click install is broken upstream, see workaround.

✨ Features

  • 🔐 Authentication - Connect with your Yazio account
  • 📊 Nutrition Analysis - Get comprehensive diet data and insights
  • 🍎 Food Tracking - Search, add, and manage food entries
  • 🏃‍♂️ Fitness Data - Track exercises and water intake
  • ⚖️ Weight Monitoring - View weight history and trends
  • 🎯 Goal Management - Access and manage nutrition goals
  • 🔍 Product Search - Search Yazio's extensive food database

🚀 Quick Start

Add the following JSON your MCP client configuration:

{
  "mcpServers": {
    "yazio": {
      "command": "npx",
      "args": ["-y", "yazio-mcp"],
      "env": {
        "YAZIO_USERNAME": "your_email@emai.com",
        "YAZIO_PASSWORD": "your_password"
      }
    }
  }
}
Claude Desktop (Extension)

[!WARNING] One-click .mcpb install is broken by a Claude Desktop bug (mcpb#281). Workaround: download yazio-mcp.zip, extract it, and use Settings → Extensions → Advanced settings → Install Unpacked Extension. Or just use the npx config above.

Claude Desktop (Manual)

~/Library/Application Support/Claude/claude_desktop_config.json

Claude Code (CLI)
claude mcp add yazio -e YAZIO_USERNAME=your_email@email.com -e YAZIO_PASSWORD=your_password -- npx -y yazio-mcp

Verify with claude mcp list.

Cursor

There are a few ways to add the server:

  • Settings UI (easiest) — Settings → MCP → + Add new MCP server, then fill in the command, args, and env
  • Project config — add JSON to .cursor/mcp.json in your project root
  • Global config — add JSON to ~/.cursor/mcp.json (applies to all projects)

💡 Use Cases

"Get my nutrition data for the last week and analyze my eating patterns"

Claude can retrieve your daily summaries, identify trends, and provide insights about your eating habits, macro distribution, and areas for improvement.

🔍 Search Food Products

"Search for 'chicken breast' in the Yazio database"

Find detailed nutritional information for any food product, including calories, macros, vitamins, and minerals.

📝 Add Forgotten Meals

"Add 200g of grilled salmon for yesterday's dinner"

Easily log meals you forgot to track in the Yazio app directly from Claude or Cursor.
