• Advanced filtering: Filter by company, date range, and keywords
• Smart pagination: Auto-scrolling to retrieve up to 100 ads per search
• Flexible sorting: Sort by date (ascending/descending) or relevance

Installation

1. Clone the repository:

git clone <repository-url>
cd FbAdLibraryMCPServer

2. Install dependencies:

npm install

3. Install Playwright browsers:

npx playwright install

Usage

Development

npm run dev

Production

  }
}

Response Format:

MCP Client Connection

Connect to the server using any MCP-compatible client:

HTTP Transport:

• URL: http://localhost:3000/mcp
• Method: POST
• Headers: Content-Type: application/json

Health Check:

• URL: http://localhost:3000/healthz
• Method: GET

Architecture

• MCP Server (src/index.ts): Express HTTP server hosting MCP protocol
• Search Handler (src/mcp/searchAdsHandler.ts): Core business logic
• Web Scraper (src/scraper/scrapeFacebookAds.ts): Playwright-based Facebook scraper
• Filters (src/utils/filters.ts): Date parsing and filtering utilities

Performance Considerations

• Rate Limiting: Built-in delays between requests to avoid blocking
• Pagination: Auto-scrolling with intelligent stopping conditions
• Browser Management: Proper cleanup of Playwright browser instances
• Memory Efficiency: Streaming data processing where possible

Anti-Bot Detection Countermeasures

This server successfully bypasses Facebook's anti-bot detection through:

• Virtual Display (Xvfb): Runs non-headless browsers in cloud environments
• Natural Navigation: Mimics human browsing patterns (homepage → Ad Library)
• Simplified Browser Config: Avoids complex "stealth" techniques that trigger detection
• Smart Timeout Handling: 30-second browser launch timeout with fallback mechanisms
• Production-Optimized: Different behavior in production vs development environments

Known Limitations

• Runs in non-headless mode to avoid detection
• Limited to 100 ads per search to prevent timeouts
• Date formats depend on Facebook's display format
• Subject to Facebook's anti-bot measures

Legal & Ethical Notes

• Respects Facebook's rate limiting through built-in delays
• Does not store personal user data
• Intended for research and analysis purposes
• Users should comply with Facebook's Terms of Service

Dependencies

• @modelcontextprotocol/sdk: MCP protocol implementation
• playwright: Web scraping automation
• date-fns: Date parsing and manipulation
• express: HTTP server framework
• zod: Runtime type validation
