Food Nutrition

A large MCP server project structure with food and nutrition intelligence, providing tools, resources, and prompts for nutrition data retrieval, meal planning, and dietary analysis.

Features

• Nutrition Data Tools: Retrieve detailed nutrition information from USDA FoodData Central and Edamam APIs
• Meal Planning: Generate meal plans based on dietary requirements and preferences
• Dietary Analysis: Analyze nutritional content of meals and diets
• Resource Endpoints: Access nutrition databases and food information
• AI Prompts: Pre-built prompt templates for nutrition-related AI interactions

Installation

1. Install Python 3.11+ if not already installed.
2. (Recommended) Create and activate a virtual environment:

   python3 -m venv .venv
   source .venv/bin/activate
   

3. Install UV (optional, for fast dependency management):

   curl -LsSf https://astral.sh/uv/install.sh | sh
   

4. Install project dependencies:

   uv sync
   

Usage

To start the Food & Nutrition Intelligence MCP server:

uv run main.py

Or, if you have an entrypoint defined (e.g., via FastMCP CLI):

fastmcp run main.py

The server exposes a set of MCP tools for nutrition data, meal planning, and dietary analysis. You can interact with it via a compatible MCP client or by integrating it into your AI workflow.

Run on debug mode

npx @modelcontextprotocol/inspector uv run main.py
