How to install

For MacOS, Linux, and Windows running WSL, you can install the NPL CLI using

curl -s https://documentation.noumenadigital.com/get-npl-cli.sh | bash

or download the latest release here and add it to your $PATH. On Windows running WSL, you will need to manually add the npl executable to your PATH. The script above will not do that for you.

For Windows without WSL, you may download the latest .exe executable here

Model Context Protocol (MCP) server

Once you've installed the CLI, you can use it in MCP mode with your local AI tools.

Install in VS Code

Simply add npl-cli to your MCP configuration file, e.g.

{
  "mcpServers": {
    "npl-cli": {
      "name": "NPL CLI",
      "command": "npl",
      "args": ["mcp"]
    }
  }
}
