🥦 Nutritionix MCP Server

This is an MCP (Model Context Protocol) server for integrating with the Nutritionix API, enabling AI agents to access food search, nutrition data, and exercise calorie estimates via natural language input.

The goal of this project is to expose Nutritionix's functionality through MCP-compatible tools that can be used seamlessly by large language models and agent frameworks.

🧠 What is MCP?

MCP (Model Context Protocol) is a lightweight protocol designed to let AI agents interact with external tools and APIs in a structured and modular way. Think of it like USB for AI — this server acts as a "driver" for the Nutritionix platform.

With this MCP server, AI models can:

• 🔍 Search for common and branded food items
• 🍽️ Parse natural language meals into nutritional breakdowns
• 🏃 Estimate calories burned from exercises like running, cycling, or yoga

🚀 How to Run

To use this MCP server, you'll need:

✅ Prerequisites

• Python 3.11+
• uv – a modern Python package manager
• A supported LLM (e.g., Claude)
• A Nutritionix API App ID and App Key – get them at developer.nutritionix.com

Add this to Claude Desktop config
