💻 Usage Examples

Node.js/TypeScript Client

import {MCPClient} from '@modelcontextprotocol/client';

const client = new MCPClient('http://localhost:3001');

// Article scraping
const result = await client.callTool('scrape_article_content', {
  url: 'https://www.cnn.com/news'
});

console.log('Article:', result.extracted.title);
console.log('Consent handled:', result.cookieConsent.success);

// Screenshot capture
const screenshot = await client.callTool('get_page_screenshot', {
  url: 'https://example.com',
  fullPage: true
});

// Advanced browser automation workflow
async function browserAutomationWorkflow() {
    // List existing tabs
    const tabList = await client.callTool('manage_tabs', {
        action: 'list'
    });
    console.log('Current tabs:', tabList.tabs.length);

    // Start network monitoring
    await client.callTool('monitor_network', {
        sessionId: 'automation_session',
        action: 'start'
    });

    // Create new tab with specific URL
    const newTab = await client.callTool('manage_tabs', {
        action: 'new',
        url: 'https://example.com/dashboard'
    });
    console.log('New tab index:', newTab.tabIndex);

    // Perform drag and drop interaction
    const dragResult = await client.callTool('drag_drop', {
        sessionId: 'automation_session',
        sourceSelector: '.widget-source',
        targetSelector: '.dashboard-area'
    });
    console.log('Drag success:', dragResult.dragDrop.success);

    // Get network activity analysis
    const networkData = await client.callTool('monitor_network', {
        sessionId: 'automation_session',

    });
    console.log('Network requests:', networkData.analysis.totalRequests);

    // Navigate back in history
    const historyNav = await client.callTool('navigate_history', {

        direction: 'back',
        steps: 1
    });
    console.log('URL changed:', historyNav.historyNavigation.urlChanged);
}

Correlation Tracking

Track requests across your system using correlation IDs for batch processing, user sessions, or distributed tracing:

// Track multiple articles in a batch analysis
const batchId = 'analysis_batch_2025_001';
const articles = [
  {url: 'https://example.com/article1', id: 'item_001'},
  {url: 'https://example.com/article2', id: 'item_002'}
];

// Process with correlation tracking
for (const article of articles) {
  const result = await client.callTool('scrape_article_content', {
    url: article.url,
    correlation_id: `${batchId}_${article.id}`,
    outputFormats: ['text', 'markdown']
  });
}

// Monitor progress via SSE with correlation
const eventSource = new EventSource('http://localhost:3001/mcp');
eventSource.onmessage = (event) => {
  const data = JSON.parse(event.data);
  if (data.params?.correlationId?.startsWith(batchId)) {
    console.log(`Progress for ${data.params.correlationId}: ${data.params.progress}%`);
  }
};
