@nvidia-elements/cli

The @nvidia-elements/cli is a dual-mode command-line tool for the Elements Design System that provides both interactive CLI commands and a Model Context Protocol (MCP) server for AI assistant integration.

Purpose

This package serves two primary modes:

  1. Interactive CLI (nve command) - Command-line interface with interactive prompts for:

    • Component API discovery and search
    • Example template browsing and searching
    • Playground creation and validation
    • Project scaffolding and health checks
    • Changelog and version information
    • Design token access

  2. MCP Server (nve mcp command) - Model Context Protocol server that:

    • Exposes all CLI tools to AI assistants (Claude, Cursor, etc.)
    • Provides context-specific prompts for common tasks
    • Enables AI-assisted development with Elements components
    • Integrates Elements knowledge directly into AI workflows

Getting Started

To use the Elements CLI you must have NodeJS installed.

npm install -g @nvidia-elements/cli

nve

Usage

Command Description
nve api.list [format] Get list of all available Elements (nve-*) APIs and components.

nve project.setup [cwd] Setup or update a project to use Elements.

MCP

Quick Setup

The fastest way to configure MCP is with the setup command:

nve project.setup

This detects your package manager, configures the MCP server for both Cursor, Codex, and Claude Code, and adds Elements core dependencies to the project.

Claude Code

Install to Claude Code by adding the configuration to your .mcp.json file. Add the following configuration to your .mcp.json file (typically located at ~/.config/claude-code/.mcp.json or %APPDATA%\claude-code\.mcp.json on Windows):

{
  "mcpServers": {
    "elements": {
      "description": "NVIDIA Elements UI Design System (nve-*), custom element schemas, APIs and examples",
      "command": "nve",
      "args": ["mcp"]
    }
  }
}

After adding the configuration, restart Claude Code for the changes to take effect. The Elements MCP tools are then available for use in your conversations.

Cursor

Install to Cursor with the MCP configuration below.

// .cursor/mcp.json
{
  "mcpServers": {
    "elements": {
      "description": "NVIDIA Elements UI Design System (nve-*), custom element schemas, APIs and examples",
      "command": "nve",
      "args": ["mcp"]
    }
  }
}
