Option 2: Deploy Your Own

Deploy your own instance to Cloudflare Workers:

Click the "Deploy to Cloudflare Workers" button at the top
After deployment, your MCP will be available at: https://heroui-mcp-cloudflare.<your-account>.workers.dev/sse
Connect to Claude Code:

claude mcp add heroui npx mcp-remote https://heroui-mcp-cloudflare.<your-account>.workers.dev/sse

Or manually edit your config:

{
  "mcpServers": {
    "heroui": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://heroui-mcp-cloudflare.<your-account>.workers.dev/sse"

}

Option 3: Local Server

For running using the Wrangler CLI:

# Install dependencies
npm install

# Run locally (starts on http://localhost:8787)
npm run dev

Connect to your local instance:

Claude Code:

🛠️ How It Works

This MCP server fetches documentation directly from heroui.com and provides structured information to AI assistants. It helps ensure:

✅ Consistency - Correct HeroUI component usage across projects
✅ Efficiency - Quick component discovery prevents unnecessary custom development
✅ Accuracy - Direct access to official documentation ensures proper implementation
✅ Customization - Full support for HeroUI's slots and variants system
✅ Best Practices - Includes accessibility guidelines and proper usage patterns

📚 Example Usage
