Summary
Wraps the OpenNutrition database (300,000+ foods from USDA, CNF, FRIDA, AUSNUT) with four core operations: search by name/brand, browse paginated food lists, retrieve detailed nutrition data by ID, and barcode lookups via EAN-13. Runs fully local with Docker or Node.js, so no API keys or external calls. Reach for this when building nutrition tracking apps, recipe analyzers, or meal planning tools that need comprehensive macro/micronutrient data. The barcode lookup is solid for grocery scanning features, and the unified dataset beats dealing with fragmented nutrition APIs or unreliable crowdsourced databases.

A Model Context Protocol (MCP) server providing access to the comprehensive OpenNutrition food database with 300,000+ food items, nutritional data, and barcode lookups.
OpenNutrition addresses the longstanding issues with fragmented and unreliable nutritional data by combining authoritative public sources (USDA, CNF, FRIDA, AUSNUT). Unlike other databases that suffer from inconsistent user-generated content or restrictive commercial licensing, OpenNutrition provides transparent, comprehensive, and accurate nutritional data that's freely accessible to developers and researchers.
Tools
- Search by Name: Find foods by name, brand, or partial matches
- Browse Foods: Get paginated lists of all available foods
- Get by ID: Retrieve detailed nutritional information using food IDs
- Barcode Lookup: Find foods using EAN-13 barcodes
Installation
Docker (recommended)
The easiest way to run the server is via Docker. No build steps required.
Run the container:
docker run --rm -p 9113:3000 deadletterq/mcp-opennutrition
Then add to your MCP configuration:
"mcp-opennutrition": {
"type": "streamable-http",
"url": "http://localhost:9113"
}
From source
-
Install dependencies:
npm install -
Build the project:
npm run build -
Add to your MCP configuration (set the same version of node that you used to build the project):
"mcp-opennutrition": { "command": "/Users/YOUR.USERNAME/.nvm/versions/node/v20.19.0/bin/node", "args": [ "/ABSOLUTE/PATH/TO/PARENT/FOLDER/mcp-opennutrition/build/index.js" ] }
Data Source
This server uses the OpenNutrition dataset.
The dataset provides comprehensive nutritional profiles including macronutrients, vitamins, and minerals.
Usage
Once configured, the MCP server runs fully locally on your machine and automatically provides food and nutrition query capabilities to Claude/Cline. All data processing and queries happen locally with no external API calls, ensuring privacy and fast response times.
Example
Here is an example of how Claude uses the tool for a brownie recipe:
