🚀 Claude Code CLI Integration

This MCP is optimized for Claude Code CLI and provides seamless integration for professional UI development workflows.

Automatic Framework Detection

Claude Code CLI automatically detects your project's framework and applies UI Expert tools accordingly:

# Claude Code automatically identifies React/Vue/Next.js projects
claude-code "Improve this project's UI design"
# → UI Expert MCP analyzes framework and suggests appropriate improvements

Project-Wide UI Enhancement

# Analyze and improve entire project UI
claude-code "Make this project's UI more professional and modern"
# → Automatically applies design tokens, improves components, and ensures consistency

# Batch component improvement
claude-code "Improve all components in the /components folder"
# → Each component gets enhanced with modern patterns and accessibility

Real-time Code Enhancement

// When Claude Code encounters basic UI code like this:
<button onClick={handleClick}>Click me</button>

// UI Expert MCP automatically suggests professional improvements:
<Button 
  variant="primary" 
  size="md" 
  onClick={handleClick}
  className="focus-visible:ring-2 focus-visible:ring-primary-500"
  aria-label="Submit form"
>
  Click me
</Button>

Context-Aware Improvements

Claude Code CLI passes rich project context to UI Expert MCP:

• Framework Detection: Automatically identifies React, Vue, Angular, etc.

• Design System Analysis: Understands existing patterns and colors

• Component Relationships: Maintains consistency across related components

• Accessibility Requirements: Applies WCAG 2.1 standards automatically

• Design system discussions

• Accessibility enhancement needs

Usage Examples

Claude Desktop Integration

Once configured, you can use the UI Expert tools in Claude Desktop:

1. Analyze your current UI:

   "Please analyze my React app's UI and suggest improvements. 
   Main issues: inconsistent colors, poor mobile layout, and confusing navigation."

2. Generate a design system:

   "Create a modern design token system for my startup. 
   Our primary color is #10b981 and we need both light and dark modes."

3. Improve a component:

   "Here's my Button component code. Can you improve it with better accessibility 
   and add loading states?"

4. Create a new component:

   "Create a responsive Card component for React with image support 
   and action buttons."

Claude Code CLI Workflows

# Professional UI development workflow
