Ghost Browser MCP

Undetectable browser automation for MCP-compatible AI agents.

Improved fork of Stealth Browser MCP adapted as Ghost Browser MCP.

Ghost Browser MCP turns a real browser into a full MCP-native research, extraction, and page-reconstruction toolkit. It combines 225 browser tools across 32 sections, Chrome DevTools Protocol access, network inspection, asset downloading, and pixel-accurate page cloning in one agent-ready server.

Bypass Cloudflare, antibot systems, and social media blocks with real browser instances powered by nodriver + Chrome DevTools Protocol + FastMCP.

Ghost Browser MCP bypassing Cloudflare, cloning UI elements, and intercepting network traffic — all through AI chat commands.

What Ghost Adds

Ghost Browser MCP is more than a browser controller. It is a practical reverse-engineering and reconstruction toolkit for authorized web analysis:

225 MCP tools across 32 sections — Navigation, screenshots, DOM extraction, CDP commands, network tracing, downloads, sessions, hooks, and page-state inspection.
Pixel-accurate cloning — Extract page structure, styles, computed layout, screenshots, and loaded assets to recreate pages in minutes.
Asset-aware extraction — Download the images, icons, fonts, CSS, and media actually loaded by the current page instead of collecting unrelated noise.
Deep page intelligence — Inspect HTML, accessibility data, console logs, network requests, storage, cookies, event listeners, and element relationships.
Manual-login handoff — Let a human complete authentication in a real browser, then return control to the AI agent with the same session.

Features

Antibot bypass — Works on Cloudflare, Queue-It, and other protection systems that block traditional automation
225 tools across 32 sections — From basic navigation to advanced CDP domain management
Modular loading — Run the full tool suite or a minimal 23-tool core; disable what you don't need
Pixel-accurate element cloning — Extract complete elements with all CSS, DOM structure, events, and assets via CDP
Network interception — Inspect every request, response, header, and payload through your AI agent
Dynamic hook system — AI-generated Python functions that intercept and modify network traffic in real-time
Instant text input — Paste large content via CDP or type with human-like keystrokes and newline support
Cross-platform — Windows, macOS, Linux, and CI/CD pipelines with automatic environment detection
Browser support — Chrome, Chromium, and Microsoft Edge (automatic detection)
Clean MCP integration — No custom brokers or wrappers; works with Claude Code, Claude Desktop, Cursor, and any MCP client

How It Fits Together

Your AI agent
  -> talks to Ghost Browser through MCP (stdio)
  -> Ghost Browser controls Chrome/Chromium
  -> Chrome opens websites, clicks, extracts data, screenshots, assets, and network info

Quickstart

1. Install uv

Windows (PowerShell):

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

macOS / Linux:

curl -LsSf https://astral.sh/uv/install.sh | sh

Or see the official installation docs: https://docs.astral.sh/uv/getting-started/installation/

2. Clone and sync

git clone https://github.com/BU3NO77XL/Ghost_Browser_MCP.git Ghost_Browser_MCP
cd Ghost_Browser_MCP
uv sync

3. Add to your MCP client

Claude Code CLI (recommended):

Windows:

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

Mac/Linux:

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

Replace /path/to/Ghost_Browser_MCP/ with your actual project path.

<details> <summary>Manual JSON configuration (Claude Desktop, Cursor, Kiro, etc.)</summary>

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

{
  "mcpServers": {
    "ghost_browser_mcp": {
      "type": "stdio",
      "command": "C:\\path\\to\\Ghost_Browser_MCP\\.venv\\Scripts\\python.exe",
      "args": ["C:\\path\\to\\Ghost_Browser_MCP\\src\\server.py"],
      "env": {
        "PYTHONPATH": "C:\\path\\to\\Ghost_Browser_MCP\\src"
      }
    }
  }
}

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

{
  "mcpServers": {
    "ghost_browser_mcp": {
      "type": "stdio",
      "command": "/path/to/Ghost_Browser_MCP/.venv/bin/python",
      "args": ["/path/to/Ghost_Browser_MCP/src/server.py"],
      "env": {
        "PYTHONPATH": "/path/to/Ghost_Browser_MCP/src"
      }
    }
  }
}

Replace /path/to/Ghost_Browser_MCP/ with your actual project path.

</details>

<details> <summary>FastMCP CLI (untested)</summary>

uv tool install fastmcp
fastmcp install claude-desktop src/server.py
# OR
fastmcp install claude-code src/server.py
# OR
fastmcp install cursor src/server.py

</details>

4. Test it

Restart your MCP client and ask your agent:

"Use ghost_browser_mcp to navigate to https://example.com and take a screenshot."

Tested on: LinkedIn, Instagram, Twitter/X, Amazon, banking portals, government sites, Cloudflare-protected APIs, Nike SNKRS, Ticketmaster, Supreme.

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 This fork includes the upstream fix for stdout corruption from #8. Re-sync the environment if you are updating an older checkout.

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

Too many tools cluttering the AI chat Use --minimal for 23 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 synchronized the project environment from the repository root:

uv sync

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 ghost 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.

Roadmap

Roadmap items are tracked in this fork and, when relevant, in the upstream repository.
