Advanced Scenarios

This guide covers advanced use cases and scenarios for Puppeteer MCP.

Overview

This section provides guidance for complex browser automation scenarios that go beyond basic usage patterns.

Advanced Browser Automation

Handling Complex Authentication Flows

When dealing with multi-step authentication processes:

// Example: OAuth flow automation
const session = await createSession();
const browser = await session.getBrowser();
const page = await browser.newPage();

// Navigate to OAuth provider
await page.goto('https://oauth-provider.com/authorize');
// Handle authentication steps...

Managing Multiple Browser Contexts

For scenarios requiring isolated browser contexts:

// Create multiple isolated contexts
const context1 = await browser.createIncognitoBrowserContext();
const context2 = await browser.createIncognitoBrowserContext();

// Each context has its own cookies, storage, etc.

Performance Optimization

Tips for optimizing browser automation performance:

1. Resource Management: Properly close pages and contexts when done
2. Parallel Execution: Use browser contexts for parallel operations
3. Request Interception: Block unnecessary resources (images, fonts) for faster page loads

Debugging Complex Scenarios

Advanced debugging techniques:

• Enable verbose logging
• Use browser DevTools protocol directly
• Capture and analyze network traffic
• Screenshot on failures for debugging

Integration Patterns

Combining Multiple Protocols

Examples of using REST, WebSocket, and MCP together for complex workflows.

Event-Driven Automation
