OpenFoodFacts MCP Server

What it does

This server provides an AI assistant with high-performance access to the Open Food Facts dataset. By utilizing DuckDB and Parquet files, it enables near-instant searches for food products, nutritional data, and brand information without relying on slow API calls.

Tools

• search_products_by_brand_and_name: Search for products using both brand and product name.
• search_by_barcode: Quickly find a specific product using its UPC or EAN barcode.
• search_products_by_brand_and_name_simplified: A token-efficient search returning only essential product fields.
