Stealth Browser MCP Server

An MCP (Model Context Protocol) server that provides stealth browser capabilities using Playwright with anti-detection techniques. This server allows MCP clients to navigate to websites and take screenshots while evading common bot detection systems.

Features

• Stealth Mode: Uses puppeteer-extra-plugin-stealth with playwright-extra to bypass bot detections

  • Modifies browser fingerprints to appear as regular user traffic

  • Handles WebGL, canvas, font, plugin and other browser fingerprinting techniques

• Screenshot Tool: Take full-page or element-specific screenshots of any website

  • Supports both headless (default) and visible browser modes

• MCP Integration: Exposes browser capabilities via Model Context Protocol
