πŸš€ Quick Start

Test Locally (Recommended Before Deployment)

  1. Build the frontend:

    npm install
    npm run build
    
  2. Install Python dependencies:

    pip install -r requirements.txt
    playwright install chromium
    
  3. Start the MCP server:

    python mcp_server_comprehensive.py
    
  4. Test in browser:

    • Open http://localhost:7860
    • Open browser console (F12)
    • You should see: βœ… window.thumbnailAPI initialized and ready
  5. Try the API:

    // In browser console:
    await window.thumbnailAPI.listLayouts()
    await window.thumbnailAPI.loadLayout('seriousCollab')
    await window.thumbnailAPI.exportCanvas()
    
  6. Test MCP endpoint:

    curl -X POST http://localhost:7860/tools \
      -H "Content-Type: application/json" \
      -d '{"name":"layout_list","arguments":{}}'

🎯 What AI Agents Can Now Do

Your AI agent can:

  1. Start from scratch:

    • Set canvas size
    • Choose background color
    • Add text with custom fonts, sizes, colors
    • Add images (Huggys or custom)
    • Position and style elements
    • Export final thumbnail
  2. Use templates:

    • Load pre-designed layouts
    • Customize text content
    • Replace placeholders with custom logos
    • Adjust colors and styling
    • Export
  3. Complex workflows:

    • Search online for images (if integrated with existing smart server)
    • Download and process assets
    • Compose multi-element designs
    • Apply consistent branding
    • Generate variations
  4. One-shot generation:

    • Single create_thumbnail call
    • Provide layout, title, subtitle, mascot
    • Get finished thumbnail in 3-5 seconds

πŸ”„ Comparison: Before vs After

Before (mcp_server_smart.py)

  • ❌ Limited to collaboration thumbnails
  • ❌ Fixed workflow (logo fetch β†’ layout β†’ export)
  • ⚠️ Only 3 tools available
  • ⚠️ No direct object manipulation
  • ⚠️ No custom layouts or text

After (mcp_server_comprehensive.py + API)

  • βœ… ALL features accessible
  • βœ… 50+ API methods
  • βœ… 17+ MCP tools
  • βœ… Complete object control
  • βœ… Custom workflows
  • βœ… Human-like capabilities

🎨 Usage Examples

Example 1: Simple Text Thumbnail

// Via window.thumbnailAPI
await window.thumbnailAPI.setCanvasSize('1200x675')
await window.thumbnailAPI.setBgColor('#f0f0f0')
await window.thumbnailAPI.addObject({
  type: 'text',
  text: 'Hello AI!',
  fontSize: 72,
  fontFamily: 'Bison',
  bold: true,
  x: 100,
  y: 100
})
const result = await window.thumbnailAPI.exportCanvas()
// result.dataUrl contains base64 image

Example 2: Layout-Based Thumbnail

await window.thumbnailAPI.loadLayout('funCollab')
await window.thumbnailAPI.updateText('title-text', 'AI-Generated Thumbnail')
await window.thumbnailAPI.addHuggy('game-jam-huggy', {x: 800, y: 300})
await window.thumbnailAPI.exportCanvas()

Example 3: Via MCP (AI Agent)

curl -X POST http://localhost:7860/tools -H "Content-Type: application/json" -d '{
  "name": "create_thumbnail",
  "arguments": {
    "layout_id": "seriousCollab",
    "title": "HuggingFace x OpenAI",
    "bg_color": "light",
    "canvas_size": "1200x675"
  }
}'

Returns complete thumbnail in one call!


🚒 Deployment Options

Option 1: Keep Both Servers

  • Deploy mcp_server_smart.py for simple logo-fetching workflows
  • Deploy mcp_server_comprehensive.py for full control
  • Let AI agents choose based on task

Option 2: Use Comprehensive Server Only

  • Update Dockerfile to use mcp_server_comprehensive.py
  • Provides superset of smart server functionality
  • Single deployment, all features

Option 3: Hybrid Approach

  • Add logo-fetching to comprehensive server
  • Combine best of both worlds
  • Most powerful but requires integration work

πŸ§ͺ Testing Checklist

Before deploying, test these scenarios:

  • npm run build completes successfully
  • Server starts without errors
  • Browser opens at http://localhost:7860
  • Console shows "βœ… window.thumbnailAPI initialized and ready"
  • Can call window.thumbnailAPI.getCanvasState() in console
  • Can load a layout via API
  • Can add objects via API
  • Can export canvas via API
  • MCP endpoint responds to layout_list tool
