AI-native stealth browser MCP server — Browser Use + Patchright

wraith-mcp

AI-native stealth browser MCP server. Tell it what to do — it figures out how.

Browser Use (AI vision navigation) + Patchright (bot detection bypass).

Why This One?

	wraith-mcp	playwright-mcp	stealth-browser-mcp	browser-use-mcp-server
Navigation	AI vision (self-healing)	CSS selectors	CSS selectors	AI vision
Bot detection bypass	Patchright (binary-level)	None	nodriver	None
Tools	2 (browse, extract)	20+	90+	via Agent
Site layout changes	Adapts automatically	Breaks	Breaks	Adapts
LLM providers	6 (Anthropic, OpenAI, OpenRouter, Google, Ollama, +compatible)	N/A	1	1

One command does it all — no selectors, no step-by-step scripting:

"Log into my dashboard and download the monthly report"

Quick Start

Add wraith-mcp as MCP server

Install

pip install wraith-mcp

Setup

Add to your MCP config (.mcp.json, .cursor/mcp.json, .windsurf/mcp.json, etc.):

{
  "mcpServers": {
    "wraith": {
      "command": "wraith-mcp",
      "env": {
        "ANTHROPIC_API_KEY": "your-key",
        "HEADLESS": "true"
      }
    }
  }
}

Works with any MCP client: Cursor, Windsurf, VS Code, Cline, Roo Code, OpenCode, Codex, and more.

Tools

Tool	Description
browse	Execute any browser task in natural language
extract	Pull structured data from a page
screenshot	Capture a page as base64 PNG
close_session	Close a persistent browser session

LLM Providers

Provider	Key
Anthropic (default)	ANTHROPIC_API_KEY
OpenRouter	OPENROUTER_API_KEY
OpenAI	OPENAI_API_KEY
DeepSeek / Groq / Together	OPENAI_API_KEY + OPENAI_BASE_URL
Google Gemini	GOOGLE_API_KEY

Docker

docker build -t wraith-mcp .
docker run -i --rm -e ANTHROPIC_API_KEY=your-key wraith-mcp

SSE mode (remote/cloud):

docker run -p 8808:8808 -e ANTHROPIC_API_KEY=your-key wraith-mcp

SSE Transport

wraith-mcp --transport sse --port 8808

How It Works

AI Agent -> MCP Server -> Browser Use Agent -> Patchright Chromium

1. Describe a task in natural language
2. Browser Use sees the page (screenshot + DOM) and decides actions
3. Patchright executes without triggering bot detection

Security

• URL scheme validation (http/https only)
• max_steps capped at 50 server-side
• Input length capped at 4000 chars
• Task timeout (default 120s, configurable via BROWSER_TASK_TIMEOUT)
• Proxy support via PROXY_SERVER

Limitations

• Binary-level stealth only (no Runtime.enable CDP fix)
• Enterprise WAFs may still block without residential proxies
• Fresh browser per call (~3s startup)
• Requires an LLM API key
