# Food & Nutrition Intelligence MCP Server

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:
   ```bash
   python3 -m venv .venv
   source .venv/bin/activate
   ```
3. Install [UV](https://github.com/astral-sh/uv) (optional, for fast dependency management):
   ```bash
   curl -LsSf https://astral.sh/uv/install.sh | sh
   ```
4. Install project dependencies:
   ```bash
   uv sync
   ```

## Usage

To start the Food & Nutrition Intelligence MCP server:

```bash
uv run main.py
```

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

```bash
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

```bash
npx @modelcontextprotocol/inspector uv run main.py
```

### Example API Usage

- **Get Nutrition Data:**
  - Tool: `nutrition_get_food_data(food_name: str, portion_size: float = 100.0, include_detailed: bool = False)`
- **Generate Meal Plan:**
  - Tool: `meal_plan_generate(dietary_preferences: dict, calories: int)`
- **Analyze Diet:**
  - Tool: `dietary_analysis(analyzed_meals: list)`

See the technical details for more tool signatures and usage patterns.
