openfoodfacts-mcp-server
Open Food Facts is the crowd-sourced database behind a lot of packaged-food apps, and this server puts its API behind four MCP tools. `off_get_product` pulls a single item by barcode with ingredients, allergen and trace tags, additives, Nutri-Score, NOVA, Green-Score, and per-100 g nutrition. `off_search_products` does text and tag search with allergen exclusions and nutrient thresholds, which is the piece you want for questions like "dairy-free snacks under 5 g sugar." `off_compare_products` lines up up to ten barcodes side by side, and `off_browse_taxonomy` resolves everyday words to the canonical tag IDs the filters require. It ships with a guidance skill that tells the model how to phrase allergy answers without overclaiming, which is worth reading before you trust it with anything safety-relevant. Runs over stdio or Streamable HTTP, and there's a public hosted instance if you just want to try it.
