### Basic Network Monitoring Workflow

```json
// 1. Start monitoring
{
  "tool": "start_network_monitoring"
}

// 2. Navigate and interact with pages
{
  "tool": "chrome_navigate",
  "arguments": {"url": "https://example.com"}
}

// 3. Get captured requests
{
  "tool": "get_network_requests",
  "arguments": {"url_filter": "api"}
}

// 4. Get response data
{
  "tool": "get_network_responses",
  "arguments": {"url_filter": "example.com"}
}

// 5. Extract specific response content
{
  "tool": "get_response_body",
  "arguments": {"request_id": "123.456"}
}
```

### Key Features

- **Full Traffic Capture**: Captures all HTTP/HTTPS requests and responses
- **Memory Protection**: Configurable circular buffer (default: 1000 entries)
- **Thread Safe**: Concurrent access with proper locking
- **Filtering**: URL pattern filtering for requests/responses
- **Complete Data**: Headers, POST data, timestamps, status codes, response bodies
- **Performance**: Optimized for high-volume traffic capture

### Use Cases

- **API Data Extraction**: Capture dynamic content loaded via AJAX/fetch
- **Authentication Token Harvesting**: Extract JWT tokens, session cookies
- **Performance Analysis**: Monitor request timing and response sizes  
- **Debugging**: Inspect network calls for troubleshooting
- **Data Mining**: Collect structured data from API endpoints

## 🧪 Testing

The project includes test scripts to validate functionality:

```bash
# Available test scripts in root directory:
python test_functions.py        # Basic function validation
python test_reddit_automation.py   # Reddit anti-detection tests
python test_undetected_chrome.py   # Core driver tests
```

### Test Results
- ✅ **Navigation**: Successfully loads protected pages
- ✅ **JavaScript Execution**: Full DOM access and data extraction
- ✅ **Screenshots**: High-quality image capture
- ✅ **Anti-Detection**: Bypasses modern bot protection (tested on Reddit)

## 🏗️ Architecture

The server follows a layered architecture:

1. **MCP Protocol Layer** - Handles MCP communication
2. **Browser Management Layer** - Manages Chrome sessions
3. **Anti-Detection Layer** - Implements stealth capabilities
4. **Operation Execution Layer** - Executes browser operations

## 🛡️ Anti-Detection Features

- **Undetected ChromeDriver**: Advanced stealth automation
- **User Agent Rotation**: Randomized browser fingerprints
- **Viewport Randomization**: Human-like window sizing
- **Human-like Delays**: Natural interaction timing
- **JavaScript Stealth**: Removes automation indicators
- **Session Isolation**: Clean state between operations
