Open Food Facts
Connects Claude to the Open Food Facts database with both read and write access. You can search products by name or barcode, filter by nutrition grades like Nutri-Score, and pull detailed ingredient and nutrition data. The server also supports write operations if you provide credentials, letting you add or update product entries and upload images directly from your conversations. Useful when you need nutritional lookups, want to compare food products, or need to contribute data to the open database. Ships with both standard search filters and Lucene syntax for complex queries, plus autocomplete for brands and categories.
