## 📡 API Usage
### MCP JSON-RPC Endpoint
**POST** `http://localhost:3000/mcp`
```json
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "browser.start_session",
"arguments": {
"opts": {
"headless": false,
"viewport": {"w": 1280, "h": 720}
}
}
}
}
```
### WebSocket Connection
Connect to `ws://localhost:3000/ws` for real-time updates:
```javascript
const ws = new WebSocket('ws://localhost:3000/ws');
ws.onmessage = (event) => {
const data = JSON.parse(event.data);
if (data.event === 'tool_call') {
console.log('Tool called:', data.data);
}
};
```
### REST Endpoints
- **GET** `/health` - Server health status
- **GET** `/tools` - List all available tools
- **GET** `/sessions` - List active sessions
- **GET** `/logs` - Recent tool call logs
## 🌐 Browser Automation
### Dynamic Session Tools
When you create a browser session, session-specific tools are automatically registered:
```json
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "browser.start_session",
"arguments": {"opts": {"headless": true}}
}
}
```
Response:
```json
{
"jsonrpc": "2.0",
"id": 1,
"result": {
"session_id": "abc123..."
}
}
```
This creates tools like:
- `browser.abc123.open` - Navigate to URL with screenshot
- `browser.abc123.click` - Click elements with visual feedback
- `browser.abc123.type` - Type text into form fields
- `browser.abc123.screenshot` - Capture screen with MCP image format
- `browser.abc123.act` - AI-driven automation with Gemini
- `browser.abc123.record` - Start/stop session recording
- `browser.abc123.replay` - Replay recorded sessions
- `browser.abc123.get_har` - Get HAR (HTTP Archive) data
### AI-Driven Browser Automation
```json
{
"method": "tools/call",
"params": {
"name": "browser.abc123.act",
"arguments": {
"goal": "Find and click the login button, then fill out the form with test credentials",
"max_steps": 10
}
}
}
```
### Example Browser Workflow

// 4. AI-driven interaction
{"method": "tools/call", "params": {
"name": "browser.abc123.act",
"arguments": {"goal": "Login with test@example.com"}
}}
// 5. End session
{"method": "tools/call", "params": {
"name": "browser.end_session",
"arguments": {"session_id": "abc123"}
}}
```
## 🔍 Search & Web Scraping

}
}
}
```
## 🎯 Image Attachments
Visual operations automatically include image attachments in proper MCP format:
```json
{
"jsonrpc": "2.0",
"id": 1,
"result": {
"content": [
{
"type": "image",
"data": "iVBORw0KGgoAAAANS...", // base64 PNG data
"mimeType": "image/png"
}
],
"width": 1280,
"height": 720,
"url": "https://example.com"
}
}
```
Images are automatically:
- Captured as PNG format
- Encoded as base64 in MCP content format
- Include proper MIME type
- Support cropping and redaction
- Embedded directly in responses (no external references)

### Adding New Namespaces
1. Create types in `src/types/yournamespace.ts`
2. Implement namespace class in `src/namespaces/yournamespace.ts`
3. Register with server in `src/server.ts`
4. Add dashboard components if needed
5. Update documentation
### Testing
```bash
# Run smoke tests
npm run test
# Test specific functionality
curl -X POST http://localhost:3000/mcp \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
# Test browser automation
curl -X POST http://localhost:3000/mcp \
-H "Content-Type: application/json" \
-d '{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "browser.start_session",
"arguments": {"opts": {"headless": true}}
}
}'
# Test database connection
curl -X POST http://localhost:3000/mcp \
-H "Content-Type: application/json" \
-d '{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/call",
"params": {
"name": "db.start_connection",
"arguments": {
"opts": {
"driver": "sqlite",
"dsn": ":memory:"
}
}
}
}'
```
## 🔒 Security Considerations
- **Secrets**: AES-256 encrypted, never logged in plaintext, only keys logged
- **Environment**: Sensitive env vars masked in info display
- **WebDriver**: Runs locally by default, configure remote carefully
- **CORS**: Restricted to dashboard origins by default
- **File Uploads**: Limited to 50MB, disabled by default
- **Rate Limiting**: Built-in 429 handling, implement upstream if needed
- **Redaction**: Frame redaction for recording privacy
- **Session Isolation**: Each browser/db session is isolated
## 🚀 Deployment
### Local Development
```bash
npm run dev
```
### Production
```bash
npm run build
npm start
```
### Docker (Coming Soon)
```bash
docker build -t mcp-fullstack .

## 🚨 Known Limitations & Compatibility
- **Node.js Version**: Some packages require Node.js 20+. Version 19.3.0 works with polyfills but Node.js 20+ recommended.
- **Image Processing**: Full image features require Node.js 20+ for optimal performance. Node.js 19.x uses canvas fallback.
- **Platform Services**: The node-windows/node-linux/node-mac packages are platform-specific and marked as optional dependencies.
- **Browser Requirements**: Chrome/Chromium required for browser automation features.
## 🛠️ Troubleshooting
### Common Issues
**Server fails to start**
- Check Node.js version (18+ required, 20+ recommended)
- Verify port is not in use: `lsof -ti:3000`
- Check environment variables in `.env`
**Browser automation fails**
- Install Chrome/Chromium
- Check if running in headless mode
- Verify WEB_DRIVER_REMOTE_URL if using remote
**Dashboard not loading**
- Build dashboard: `cd dashboard && npm run build`
- Check if files exist in `dashboard/dist/`
- Verify CORS settings
**Tools not appearing**
- Check server logs for registration errors
- Verify sessions are being created properly
- Use `/tools` endpoint to debug
**WebSocket connection fails**
- Check firewall settings
- Verify WebSocket is enabled in config
- Test with simple WebSocket client
**Service installation fails**
- **Windows**: Run PowerShell/Command Prompt as Administrator
- **Linux**: Use `sudo` for system service installation
- **macOS**: Check user permissions for LaunchAgent directory
- Verify Node.js path is accessible to service user
**PWA install not available**
- Use Chrome, Edge, or Safari (PWA-compatible browser)
- Ensure HTTPS or localhost (required for PWA)
- Check if service worker registered successfully
### Debug Mode
Run with debug logging:
```bash
