## What it does

The server hands your assistant access to Yazio nutrition data. It returns a daily summary and the food entries for a given date, plus weight history, exercises, water intake, goals and profile settings. A second group of tools searches the Yazio food database and writes to your log: a product, an amount, a date and a meal type.

Under the hood it exposes tools such as `get_user_daily_summary`, `search_products`, `add_user_consumed_item` and `remove_user_consumed_item`. Auth uses your Yazio credentials, passed through the `YAZIO_USERNAME` and `YAZIO_PASSWORD` environment variables. You need Node.js 18+ and a working Yazio account.

Yazio has no official API, so the server talks to a reverse-engineered one. That means it can break whenever Yazio changes something on their end. One-click `.mcpb` install in Claude Desktop is broken by a bug; use the unpacked extension or the `npx` config instead.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `YAZIO_USERNAME`, `YAZIO_PASSWORD` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
