Stealth Browser MCP

Stealth Browser MCP is an open-source Model Context Protocol (MCP) server engineered for undetected web automation and browser scraping. Built on top of nodriver, the Chrome DevTools Protocol (CDP), and FastMCP, it enables AI assistants like Claude Desktop, Cursor, and Windsurf to navigate bot detection systems, Cloudflare challenges, and login walls without triggering automated anti-bot defenses.

Key Technical Capabilities

• Cloudflare & Anti-Bot Resistance: Unlike standard automation frameworks that expose automated WebDriver flags, Stealth Browser MCP utilizes nodriver and low-level CDP instrumentation to replicate human-like browsing patterns and pass Turnstile/Cloudflare challenges.
• Comprehensive 97-Tool Suite: Exposes 97 granular MCP tools grouped into 11 modular categories—including DOM navigation, cookie management, session storage, network interception, screenshot capture, and raw CDP script execution.
• Modular Architecture: Allows agents to run in full 97-tool mode or a lightweight 20-tool core mode to minimize LLM context token usage.
• Pixel-Accurate Element Cloning: Capable of inspecting, extracting, and replicating complete DOM elements along with computed CSS rules, event listeners, media assets, and SVG paths.
• Dynamic Request/Response Hooks: Supports custom Python-based interceptors to rewrite headers, mock API payloads, block tracking scripts, or redirect traffic before it touches the browser.
• Cross-Platform Native Execution: Auto-discovers Chrome, Chromium, and Microsoft Edge executables across macOS, Linux, Windows, and Docker containers.
