+## 🎨 Usage Examples
+
+### Example 1: Simple Text Thumbnail
+
+```javascript
+// 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
+
+```javascript
+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)
+
+```bash
+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
+

+        "params": {"size": "linkedin"}
+      },
+      {
+        "operation": "loadLayout",
+        "params": {"layout_id": "academiaHub", "options": {}}
+      },
+      {
+        "operation": "addHuggy",
+        "params": {"huggy_id": "acedemic-huggy", "options": {}}
+      },
+      {
+        "operation": "exportCanvas",
+        "params": {"format": "png"}
+      }
+    ]
+  }
+}
+```
+

+
+## 🤖 Using with AI Agents
+
+### HuggingChat Integration
+
+1. **Deploy to Hugging Face Space** (see Deployment section)
+
+2. **Register in HuggingChat**:
+   - Settings → MCP Servers
+   - Add your Space URL: `https://huggingface.co/spaces/YOUR-USERNAME/Thumbnail-Crafter.mini`
+   - Enable it
+
+3. **Use Natural Language**:
+
+```
+You: "Create a collaboration thumbnail for Hugging Face and OpenAI using
+     the Serious Collab layout with a light blue background"
+
+HuggingChat:
+  [Calls layout_load with 'seriousCollab']
+  [Calls canvas_set_bg_color with '#e0f2ff']
+  [Calls text_update to customize titles]
+  [Calls canvas_export]
+
+  Here's your thumbnail! [displays image]
+```
+
+### Claude Desktop / Claude Code
+
+If using Claude with MCP:
+
+1. Configure MCP server in Claude desktop
+2. Point to your server endpoint
+3. Claude will automatically discover tools from `tools_comprehensive.json`
+
+### Custom AI Agents
+
+Use the MCP protocol:
+
+```python
+import requests
+
+def call_thumbnail_tool(tool_name, arguments):
+    response = requests.post(
+        "http://localhost:7860/tools",
+        json={"name": tool_name, "arguments": arguments},
+        stream=True
+    )
+
+    for line in response.iter_lines():
+        if line:
+            data = json.loads(line)
+            if data.get("output"):
+                return data.get("data")
+```
+
+---
+
+## 📦 Deployment to Hugging Face
+
+### 1. Update Dockerfile

+
+---
+
+## 🔧 Troubleshooting
+
+### API Not Available
+
+**Issue**: `window.thumbnailAPI is undefined`
+
+**Solutions**:
+- Wait for app to fully load (check console for initialization message)
+- Ensure React app is built (`npm run build`)
+- Check browser console for errors
+
+### Playwright Errors
+
+**Issue**: Browser fails to launch
+
+**Solutions**:
+```bash
+# Reinstall Playwright
+playwright install chromium
+playwright install-deps chromium
+
+# On Linux, may need additional dependencies
+apt-get install -y libglib2.0-0 libnss3 libx11-6
+```
+
+### Tool Not Found
+
+**Issue**: MCP client says tool doesn't exist
+
+**Solutions**:
+- Check `tools_comprehensive.json` is properly formatted
+- Ensure tool name matches exactly (case-sensitive)
+- Verify MCP server is using correct tools file
+
+### Export Returns Empty Image
+
+**Issue**: Canvas export is blank
+
+**Solutions**:
+- Wait longer before exporting (add delays)
+- Check canvas actually has objects (`canvas_get_state`)
+- Ensure canvas ref is properly initialized
+
+---
+
+## 📊 Performance Considerations
+
+### Typical Operation Times
+
+| Operation | Time (warm) | Time (cold) |
+|-----------|-------------|-------------|
+| Canvas state | <100ms | <100ms |
+| Load layout | ~1s | ~1s |
+| Add object | ~500ms | ~500ms |
+| Export image | ~1s | ~1s |
+| **Complete thumbnail** | **~3-5s** | **~8-12s** |
+
+### Optimization Tips
+
+1. **Keep browser warm**: Don't close browser between requests
+2. **Use batch operations**: Combine multiple ops into one call
+3. **Use `create_thumbnail`**: Most efficient for full workflow
+4. **Cache layouts**: Load once, customize multiple times
+
+---
+
+## 🎨 Advanced Use Cases
+
+### 1. Dynamic Branding
+
+```javascript
+// Create thumbnails with consistent branding
+const brandConfig = {
+  canvas_size: "1200x675",
+  bg_color: "#1a1a2e",
+  font_family: "Bison",
+  brand_color: "#00d9ff"
+};
+
+await window.thumbnailAPI.setCanvasSize(brandConfig.canvas_size);
+await window.thumbnailAPI.setBgColor(brandConfig.bg_color);
+// Add branded elements...
+```
+
+### 2. Template System
+
+```javascript
+// Save state as template
+const template = await window.thumbnailAPI.getCanvasState();
+// Store template.objects
+
+// Later, restore template
+await window.thumbnailAPI.clearCanvas();
+for (const obj of template.objects) {
+  await window.thumbnailAPI.addObject(obj);
+}
+```
+
+### 3. Automated Testing
+
+```javascript
+// Test canvas operations
+async function testThumbnailCreation() {
+  await window.thumbnailAPI.clearCanvas();
+  await window.thumbnailAPI.loadLayout('seriousCollab');
+
+  const state = await window.thumbnailAPI.getCanvasState();
+  assert(state.objects.length > 0, "Layout should add objects");
+
+  const result = await window.thumbnailAPI.exportCanvas();
+  assert(result.success, "Export should succeed");
+}
+```
