Setup

Prerequisites: Python 3.12+, uv, a Windy API key

1. Clone the repository and install dependencies:

   git clone https://github.com/yourusername/windy-mcp-server.git
   cd windy-mcp-server
   uv sync
   

2. Create a .env file with your API key:

   cp .env.example .env
   # Edit .env and set WINDY_API_KEY=your_api_key_here
   

3. Add to your MCP client config (e.g. claude_desktop_config.json):

   {
     "mcpServers": {
       "windy": {
         "command": "uv",
         "args": ["run", "python", "server/server.py"],
         "cwd": "/path/to/windy-mcp-server",
         "env": {
           "WINDY_API_KEY": "your_api_key_here"
         }
       }
     }
   }
