WireUI MCP Server

An MCP (Model Context Protocol) server that provides AI tools with deep understanding of WireUI v2.x components and comprehensive icon support for Heroicons and Phosphor Icons.

What is the TALL Stack?

TALL is a full-stack development solution that combines:

• Tailwind CSS - Utility-first CSS framework

Overview

This MCP server enables AI assistants like Claude to:

• Query WireUI component metadata (props, slots, events)
• Get usage examples with Blade syntax
• Understand Livewire and Alpine.js integrations
• Generate properly structured TALL stack UI code
• Check icon availability across Heroicons and Phosphor libraries
• Find similar icons with fuzzy matching for typos
• Get icon usage examples with all variants

Requirements

• Node.js 18+
• Compatible with WireUI v2.4+
• Supports Laravel 10-12, Livewire 3, Tailwind CSS 3 (v4 not supported by WireUI v2)

Quick Start Guide

1. Clone and Install

# Clone the repository
git clone https://github.com/rcoenen/wireui-mcp-server.git
cd wireui-mcp-server

# Install dependencies
npm install

# Build the server
npm run build

2. Test with MCP Inspector (Recommended for First-Time Users)

The easiest way to test the server is using the MCP Inspector:

# Run this command from the project directory
npx @modelcontextprotocol/inspector node dist/index.js

This will:

1. Start the MCP Inspector
2. Open your browser automatically
3. Show the Inspector interface

In the browser, you'll see a form. Enter these values:

• Command: node
• Arguments: /Users/YOUR_USERNAME/Dev/wireui-mcp-server/dist/index.js (adjust path to match your setup)

Click "Connect" and you should see:

• "Connected" status
• In the console: "Loaded 26 components"
• Available tools in the Tools tab

3. Try the Tools

Once connected, test the tools:

1. List all components:

   • Select tallui_list_components
   • Click "Run"
   • You should see all 26 WireUI components listed

2. Get component details:

   • Select tallui_get_component
   • Enter arguments: {"name": "button"}
   • Click "Run"

3. Search components:

   • Select tallui_search_components
   • Enter arguments: {"query": "form"}
   • Click "Run"
   • This will return all form-related components

Using with Claude Desktop

Add to your Claude Desktop configuration (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "tall-ui": {
      "command": "node",
      "args": ["/path/to/wireui-mcp-server/dist/index.js"]
    }
  }
}

Restart Claude Desktop and the TALL UI tools will be available.

Icon Support (NEW! v1.1.0)

⚠️ Installation Requirements

The MCP server provides metadata about icons, but the actual icon packages must be installed separately in your Laravel project:

# For Heroicons support
composer require wireui/heroicons

# For Phosphor Icons support
composer require wireui/phosphoricons

Note: The MCP server tools will remind you about these installation requirements when you use them. Each tool response includes the necessary installation commands.

Icon Libraries Coverage

Library	Icons	Variants	Total Combinations
Heroicons	324	outline, solid, mini.solid	972
Phosphor	1,000+	thin, light, regular, bold, fill, duotone	6,000+

Icon Features

1. Smart Icon Validation

   • Checks if icons exist before use
   • Validates variant availability
   • Prevents runtime errors from missing icons

2. Fuzzy Matching

   • Finds similar icons when typos occur
   • Suggests alternatives for non-existent icons
   • Example: "usr" → suggests "user", "users"

3. Usage Examples

   • Shows correct syntax for each icon library
   • Provides examples for all variants
   • Includes component syntax alternatives

Example Icon Tool Usage

// Check if an icon exists
wireui_check_icon({ name: "user", library: "heroicons" })
// Returns: { exists: true, variants: ["outline", "solid", "mini.solid"] }

// Find similar icons (typo handling)
wireui_find_similar_icons({ name: "usr" })
// Returns suggestions: "user", "users", etc.

// Get usage examples
wireui_get_icon_example({ name: "user", library: "heroicons" })
// Returns Blade syntax examples for all variants

Development

# Run in development mode
npm run dev

# Run tests
npm test

# Type check
npm run typecheck

# Update icon data
npm run update-icons

Component Structure

Components are defined as JSON files in src/components/wireui/:

{
  "name": "button",
  "category": "actions",
  "wireui_version": "^2.4",
  "props": [...],
  "slots": [...],
  "examples": [...]
}

Adding New Components

1. Create a JSON file in src/components/wireui/
2. Follow the schema defined in src/registry/schema.ts
3. Include version compatibility, props, examples, and best practices
4. Rebuild with npm run build
5. Restart the server to load new components

Troubleshooting

"ENOENT: no such file or directory" error

Make sure you're running commands from the project root directory, not from a subdirectory.

Inspector won't connect

1. Ensure the server is built: npm run build
2. Check the path in Arguments matches your actual file location
3. Try using the full absolute path

Components not loading

Check that JSON files in src/components/wireui/ are valid JSON format.
