Overview

The Open Food Facts MCP server connects MCP clients to the Open Food Facts API for product lookup, search, and contributions. It supports barcode queries, structured filters, Lucene search, autocomplete, product edits, image handling, and direct API calls. Set a user agent for API access; write operations additionally require Open Food Facts credentials. Use it when an agent needs food product information or needs to add and update database records.

Use cases

  • Look up nutrition data by product barcode
  • Search products by brand, category, or Nutri-Score
  • Explore brands and labels with autocomplete
  • Add or update product records
  • Upload and adjust product images

Key features

  • Barcode product lookup
  • Structured product search
  • Lucene query support
  • Product and image contributions
  • Direct Open Food Facts API access
  • API documentation lookup

How Open Food Facts works

What Open Food Facts MCP server does

The Open Food Facts MCP server gives an MCP client access to product data from the Open Food Facts database and API. It supports both read and write workflows, so an agent can inspect an existing item, search across products, or contribute product details when authenticated.

Typical read tasks include finding a product from its barcode, retrieving nutrition information, locating products by brand or category, and filtering by Nutri-Score. The server can also help explore database vocabulary by suggesting brands, categories, labels, and similar values.

Write workflows can create or update a product, upload a product image, and select, crop, or rotate an image. These operations modify Open Food Facts data and should be used with the required account credentials.

How it works

The Open Food Facts MCP server exposes the Open Food Facts API through MCP tools. A client sends a tool request, and the server performs the corresponding database or API operation. Product lookup uses a barcode, while standard search accepts structured filters such as brand, category, and Nutri-Score.

For more advanced queries, Lucene search supports syntax including negation and boolean logic. The call_api tool provides a lower-level way to reach Open Food Facts API endpoints directly, and get_api_docs returns API documentation for discovering endpoint details.

This server fits assistants that need food catalog data during conversations, product research, nutrition lookups, or data contribution tasks. It is less suitable when an application requires a separate private product database or capabilities not exposed by the Open Food Facts API.

Setup and configuration

Configure the server in an MCP client using the installation instructions linked by the project. The referenced setup flow generates client configuration and lists support for Claude Code, Claude Desktop, Cursor, Cline, VS Code, and other clients.

OFF_USER_AGENT is required. Set it to an identifying value for the application, such as an application name, version, and contact address. The server uses the world country subdomain by default; set OFF_COUNTRY to select another country subdomain.

Read-only tools do not require an Open Food Facts account. To add or edit products or upload images, set both OFF_USER_ID and OFF_PASSWORD. The authentication requirement for call_api depends on the endpoint being called.

Tools and capabilities

  • get_product: Retrieves product information by barcode.
  • search_products_standard: Searches with structured brand, category, and Nutri-Score filters.
  • search_products_lucene: Runs Lucene queries with boolean logic and negation.
  • autocomplete: Suggests brands, categories, labels, and other database terms.
  • add_or_edit_product: Creates or updates a product record.
  • upload_image: Uploads a product image.
  • select_image: Selects, crops, and rotates an image.
  • call_api: Calls an Open Food Facts API endpoint directly.
  • get_api_docs: Retrieves Open Food Facts API documentation.

Limitations and notes

Write tools need Open Food Facts credentials, while read tools do not. Direct API calls may also require authentication depending on the selected endpoint. The server depends on the data and endpoint behavior provided by Open Food Facts, and its country context defaults to the world subdomain unless configured otherwise.
