DatabasesTypeScriptv2.6.0

openfoodfacts-mcp

MCP server for the Open Food Facts API - search, read, and contribute to the world's largest open food database.

Use Cases

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.

Setup

Follow the instructions on install-mcp, which generates the right config for your MCP client (Claude Code, Claude Desktop, Cursor, Cline, VS Code, and more).

Set OFF_USER_AGENT to identify your app (e.g. openfoodfacts-mcp/1.2.0 (you@example.com)). For write operations (adding/editing products, uploading images), also set OFF_USER_ID and OFF_PASSWORD.
