MCP server for the Open Food Facts API - search, read, and contribute to the world's largest open food database.
Look up a product by name: "How many calories in a Sainsbury's buffalo chicken wrap?" -> searches by name, finds the product, and returns nutrition data.
Look up a product by barcode: "What's in this product with barcode 3017620422003?" -> fetches Nutella's ingredients, Nutri-Score, and nutrition data.
Find healthy options: "Search for breakfast cereals with Nutri-Score A" -> searches with category and nutrition grade filters.
Contribute data: "Add the product name and brand for barcode 12345678" -> creates or updates a product entry on Open Food Facts.
Explore the database: "What brands of organic chocolate are in the database?" -> uses autocomplete and search to explore.
