How do I use Stealth Browser MCP?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Stealth Browser MCP scrape product prices from a Cloudflare-protected e-commerce site" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

Quickstart

1. Clone and install

git clone https://github.com/vibheksoni/stealth-browser-mcp.git cd stealth-browser-mcp python -m venv venv # Activate virtual environment # Windows: venv\Scripts\activate # Mac/Linux: source venv/bin/activate pip install -r requirements.txt

2. Add to your MCP client

Claude Code CLI (recommended):

Windows:

claude mcp add-json stealth-browser-mcp "{\"type\":\"stdio\",\"command\":\"C:\\path\\to\\stealth-browser-mcp\\venv\\Scripts\\python.exe\",\"args\":[\"C:\\path\\to\\stealth-browser-mcp\\src\\server.py\"]}"

Mac/Linux:

claude mcp add-json stealth-browser-mcp '{ "type": "stdio", "command": "/path/to/stealth-browser-mcp/venv/bin/python", "args": ["/path/to/stealth-browser-mcp/src/server.py"] }'

Replace /path/to/stealth-browser-mcp/ with your actual project path.

Windows (%APPDATA%\Claude\claude_desktop_config.json):

{ "mcpServers": { "stealth-browser-mcp": { "command": "C:\\path\\to\\stealth-browser-mcp\\venv\\Scripts\\python.exe", "args": ["C:\\path\\to\\stealth-browser-mcp\\src\\server.py"], "env": {} } } }

Mac/Linux (~/Library/Application Support/Claude/claude_desktop_config.json):

{ "mcpServers": { "stealth-browser-mcp": { "command": "/path/to/stealth-browser-mcp/venv/bin/python", "args": ["/path/to/stealth-browser-mcp/src/server.py"], "env": {} } } }

pip install fastmcp fastmcp install claude-desktop src/server.py --with-requirements requirements.txt # OR fastmcp install claude-code src/server.py --with-requirements requirements.txt # OR fastmcp install cursor src/server.py --with-requirements requirements.txt

3. Test it

Restart your MCP client and ask your agent:

"Use stealth-browser to navigate to https://example.com and take a screenshot."

Troubleshooting

No compatible browser found Install Chrome, Chromium, or Microsoft Edge. The server auto-detects the first available browser. Run validate_browser_environment_tool() to diagnose.

Tools hang or return malformed JSON Debug output was printing to stdout, corrupting the MCP JSON-RPC protocol. This was fixed in #8. Pull the latest master branch.

Browser crashes on Linux / Docker / CI Run with --sandbox=false or ensure your environment supports sandboxing. The server auto-detects root and container environments and adjusts accordingly.

Too many tools cluttering the AI chat Use --minimal for 22 core tools, or selectively disable sections:

python src/server.py --disable-cdp-functions --disable-dynamic-hooks --disable-progressive-cloning

Module not found errors Make sure you activated the virtual environment and installed dependencies:

pip install -r requirements.txt

Examples

Market research — Extract pricing and features from competitors, output a comparison table
UI cloning — Recreate a pricing section with exact fonts, styles, and interactions
Inventory monitoring — Watch a product page and alert when stock changes
API reverse engineering — Intercept requests, map endpoints, and inspect data flow

All driven from a single AI agent conversation.

Showcase

Augment Code hero clone — A user asked Claude to clone the hero section from augmentcode.com. The agent spawned a stealth browser, navigated to the site, extracted the complete element via CDP (styles, structure, assets), and generated a pixel-accurate HTML recreation with responsive design and animations. The entire process took under two minutes of conversation.
