This plugin leverages the Nushell MCP server for:

• Code validation: Generated code is checked via nu-check
• Live evaluation: Test snippets directly through MCP
• Command discovery: Access to list_commands and command_help

Ensure your MCP configuration includes:

{
  "mcpServers": {
    "nushell": {
      "command": "nu",
      "args": ["--mcp"]
    }
  }
}
