Claude Desktop Setup

To use this MCP server with Claude Desktop, add the following configuration to your claude_desktop_config.json file:

macOS

# Edit the config file
open ~/Library/Application\ Support/Claude/claude_desktop_config.json

Windows

# Navigate to the config file location
%APPDATA%\Claude\claude_desktop_config.json

Configuration

Add this server configuration to your claude_desktop_config.json:

{
  "mcpServers": {
    "mealplan": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/to/your/mealplan-mcp",
        "run",
        "main.py"
      ],
      "env": {
        "MEALPLANPATH": "/path/to/your/meal/plans"
      }
    }
  }
}

Important:

• Replace /path/to/your/mealplan-mcp/main.py with the actual path to your main.py file
• Replace /path/to/your/meal/plans with your desired meal plan storage directory
• Restart Claude Desktop after making changes

Development Setup

Prerequisites

• Python 3.12 or higher
• uv (recommended for dependency management)

Installation

1. Clone the repository:

   git clone <repository-url>
   cd mealplan-mcp
   

2. Set up the environment variable for meal plan storage:

   # macOS/Linux
   export MEALPLANPATH="/path/to/meal/plans"
   
   # Windows Command Prompt
   set MEALPLANPATH=C:\path\to\meal\plans
   
   # Windows PowerShell
   $env:MEALPLANPATH = "C:\path\to\meal\plans"
   

3. Set up the virtual environment:

   # Using uv (recommended)
   uv venv
   source .venv/bin/activate  # On macOS/Linux
   # .venv\Scripts\activate    # On Windows
   
   # Alternative: Using venv (built-in)
   python -m venv .venv
   source .venv/bin/activate  # On macOS/Linux
   # .venv\Scripts\activate    # On Windows
   

4. Install dependencies:

   # For basic usage (recommended)
   uv pip install -e .
   
   # For development (includes testing tools)
   uv pip install -e ".[dev]"
   
   # Alternative: Using pip
   pip install -e .              # Basic usage
   pip install -e ".[dev]"       # Development
   

Running the Application

To start the MCP server:

python main.py

This starts the server using stdio transport, making it compatible with MCP client applications.

Testing

The project includes comprehensive testing with automatic test isolation:

# Run all tests
pytest

# Run with coverage
pytest --cov=mealplan_mcp

# Generate a coverage report
pytest --cov=mealplan_mcp --cov-report=html

# Run specific test categories
pytest tests/mealplan/          # Meal plan tests
pytest tests/dish/              # Dish service tests
pytest tests/renderers/         # Renderer tests

MCP Examples

Using the MCP CLI Tool

The MCP CLI tool allows you to interact with your server directly from the command line:

# In a separate terminal, run your server
python main.py

# In another terminal, start the MCP CLI
mcp dev main.py
