What is the Stealth MCP Server?

Undetectable browser automation for AI agents via the Model Context Protocol.

What it actually does

A self-contained stealth Chrome DevTools MCP server with smart profile management, anti-detection stealth arg filtering, and robust process lifecycle handling. Built on nodriver (CDP-based) for full anti-bot evasion.

  • Undetectable by anti-bot systems — — Cloudflare, DataDome, PerimeterX, etc
  • Smart profile management — — master/snapshot/clone strategy preserves logins across sessions
  • Stealth arg filtering — — automatically strips 30+ detectable Chrome flags (Puppeteer/Playwright signatures, automation markers)
  • Multi-instance support — — spawn and manage multiple browsers simultaneously
  • A shared backend across sessions — — every client session proxies to a shared
  • Auto-suffix busy profiles — — github-session auto-becomes github-session-2 when occupied

Configuration

  • Python 3.11+ - Chrome, Chromium, or Microsoft Edge - uv (recommended) or pip - A desktop session for headed browsing (headless works from SSH, CI, and services)
