Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account fliptheweb for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Unofficial MCP server that connects an assistant to a Yazio account to read nutrition, fitness and weight data and log meals and water.

What you can do: Read profile, settings, dietary preferences and nutrition goals
Retrieve daily nutrition summaries, consumed food entries, water intake, exercises and weight data by date or range
Search the Yazio food database and fetch detailed product information by ID
Add or remove logged food items and log cumulative water intake
When to use it: Useful when you already track diet in Yazio and want an assistant to analyze eating patterns, look up product nutrition, or backfill forgotten meals and water entries without opening the app.
Requirements: Runs locally via npx, so Node.js 18+ is needed, plus an MCP-compatible client. Requires a valid Yazio account and the YAZIO_USERNAME and YAZIO_PASSWORD environment variables; network access to Yazio servers is required.

Before you install

Your Yazio account credentials are passed as environment variables and used to sign in to Yazio servers. The server relies on an unofficial reverse-engineered API that may break at any time. It can add and remove entries in your consumption log and change water intake, so writes affect real tracking data.

Installation

In SourceWeft

Open Yazio Mcp in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

Yazio MCP Server [Yazio Logo]

[!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

🚀 Quick Start

Add the following JSON your MCP client configuration:

json

{  "mcpServers": {    "yazio": {      "command": "npx",      "args": ["-y", "yazio-mcp"],      "env": {        "YAZIO_USERNAME": "[email protected]",        "YAZIO_PASSWORD": "your_password"      }    }  }}

{  "mcpServers": {    "yazio": {      "command": "npx",      "args": ["-y", "yazio-mcp"],      "env": {        "YAZIO_USERNAME": "[email protected]",        "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
