Prerequisites

1. Python >= 3.13
2. uv (Python package manager)
3. LINE Shopping API Key (X_API_KEY)

Installation

Method 1: Using uvx (Recommended)

Install and run directly from PyPI using uvx:

# Install and run the MCP server (note the different executable name)
uvx --from lineshopping-api-mcp lineshopping-mcp

Or run with environment variables:

# Set your API key and run
X_API_KEY=your_api_key_here uvx --from lineshopping-api-mcp lineshopping-mcp

Method 2: Clone and Run

1. Clone the repository:

   git clone https://github.com/woraphol-j/lineshopping-api-mcp.git
   cd lineshopping-api-mcp
   

2. Install dependencies:

   uv add fastmcp httpx
   

3. Run the server:

   # Set your API key and run
   X_API_KEY=your_api_key_here uv run --with fastmcp fastmcp run app.py
   

Environment Configuration

For persistent configuration, create a .env file in your working directory:

X_API_KEY=your_api_key_here
