An open-source [Model Context Protocol](https://modelcontextprotocol.io) server that gives
any LLM access to **food nutrition data** — look up products by barcode, search by name,
read Nutri-Score / NOVA / Eco-Score ratings, and compare products side by side.

Powered by [Open Food Facts](https://world.openfoodfacts.org), a free, open, crowd-sourced
food products database. No API key required.

## Tools

| Tool | Description |
| --- | --- |
| `get_product_by_barcode(barcode)` | Full nutrition facts, scores, allergens & ingredients for a barcode (EAN/UPC). |
| `search_products(query, page_size=5)` | Search products by name or brand; returns barcodes + a nutrition summary. |
| `get_nutrition_scores(barcode)` | Nutri-Score (A–E), NOVA processing group (1–4), and Eco-Score for a product. |
| `compare_products(barcodes)` | Side-by-side per-100g comparison table for 2+ products. |
| `find_healthier_alternative(barcode, limit=5)` | Suggest same-category products with a better Nutri-Score. |
| `add_or_update_product(...)` | **Optional / opt-in.** Create or edit a product. Only enabled when credentials are set (see below). |

Reading needs **no API key or account** — it's open data. Only the optional write
tool requires an Open Food Facts login.
