- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
Clone the repository, install dependencies with uv pip install -r requirements.txt, and configure environment variables—notably the required OUTPUT_DIR (must exist before starting). Start the server with uv run --with python-dotenv --with mcp src/server.py. Connect your MCP Client and invoke the available tools, providing the path to a GRIB2 file. A sample script (src/sample/sample.py) demonstrates usage patterns.
