Casos de uso

Usos del mundo real: stealth-browser-mcp

How to scrape data from a Cloudflare-protected site for authorized research

👤 Researchers and data analysts who need data from protected sites they have permission to access ⏱ ~15 min intermediate

Cuándo usarlo: You need to extract data from a site you're authorized to access but standard scraping tools get blocked.

Requisitos previos

stealth-browser-mcp installed — Clone repo, pip install -r requirements.txt
Authorization to access the target site — Ensure you have permission to scrape the site

Flujo

Navigate to the site

Open a stealth browser and navigate to https://example.com/data. Wait for the page to fully load.✓ Copiado

→ Page loaded successfully, bypassing protection
Extract data

Query all elements matching the product listing cards. Extract titles, prices, and URLs.✓ Copiado

→ Structured data from the page

Resultado: Data extracted from the protected site for authorized analysis.

Errores comunes

Running too many concurrent browsers — Keep to 1-2 browser instances at a time to avoid detection patterns

Combinar con: filesystem

Clone a UI element pixel-perfect for design reference

👤 Frontend developers who want to study and replicate a UI pattern ⏱ ~10 min intermediate

Cuándo usarlo: You see a UI component you like and want the complete HTML/CSS for reference.

Requisitos previos

stealth-browser-mcp running — Start the MCP server

Flujo

Navigate and identify

Open https://example.com and take a screenshot. I want to clone the navigation header.✓ Copiado

→ Screenshot with page rendered
Clone the element

Clone the nav header element completely — HTML structure, CSS styles, events, and animations. Save to a file.✓ Copiado

→ Complete element clone saved with all styles and assets

Resultado: A self-contained HTML/CSS clone of the UI element for reference.

Errores comunes

Cloned elements may depend on external fonts or scripts — Use extract_element_assets to also capture referenced resources

stealth-browser-mcp + filesystem

Save scraped data and cloned UI elements to organized files

Scrape all product data from the page and save it as JSON to ~/data/products.json.✓ Copiado

Seguridad

Permisos, secretos, alcance

Almacenamiento de credenciales: No credentials stored by the server. If accessing authenticated sites, manage cookies via get/set_cookie tools.

Salida de datos: Connects to whatever URLs you navigate to via Chrome

⚠ This tool is designed for authorized security research, CTF competitions, and defensive analysis only. Do not use it against systems you don't own or have written authorization to test.
Anti-bot bypass capabilities should only be used on sites you have authorization to access.
Dynamic hooks execute arbitrary Python code — review all hook functions before running.
Ensure your scraping complies with each site's Terms of Service and applicable laws.

Resolución de problemas

Errores comunes y soluciones

Chrome not found

The server uses nodriver which manages its own Chrome. Ensure Chrome is installed or let nodriver download it.

Verificar: which google-chrome || which chromium

Anti-bot detection still triggered

Try adding delays between actions, reduce concurrent requests, or use different browser profiles.

Verificar: Check the page for CAPTCHA or block messages

Element clone incomplete

Some elements use shadow DOM or iframe isolation. Use execute_cdp_command for low-level access.

Verificar: Inspect the element in DevTools to check for shadow roots

Alternativas
