camoufox-reverse-mcp

English | 中文

Anti-detection browser MCP server for JavaScript reverse engineering.

An MCP (Model Context Protocol) server that gives AI coding assistants (Claude Code, Cursor, Cline, etc.) the ability to perform JavaScript reverse engineering through the Camoufox anti-detection browser — including API parameter analysis, JS source analysis, dynamic debugging, function hooking, network interception, and cookie/storage management.

Why Camoufox?

Core Advantages:

• Camoufox modifies fingerprint information at the C++ engine level, not JS patches
• Juggler protocol sandbox isolation makes Playwright completely undetectable by page JS
• BrowserForge generates fingerprints based on real-world traffic distribution
• Works on sites with strong bot detection: Rui Shu, GeeTest, Cloudflare, etc.

Quick Start

Option 1: Install via AI Chat (Recommended)

Paste the following into your AI coding tool's chat (Cursor / Claude Code / Codex, etc.):

Please configure camoufox-reverse-mcp and refer to this MCP for related operations: https://github.com/WhiteNightShadow/camoufox-reverse-mcp

The AI will automatically clone, install dependencies, and configure the MCP server.

Option 2: Manual Installation

1. Clone the repository

git clone https://github.com/WhiteNightShadow/camoufox-reverse-mcp.git
cd camoufox-reverse-mcp

2. Install dependencies

pip install -e .

Or with uv:

uv pip install -e .

3. Configure your AI tool

Add the MCP server config to your tool's configuration file (see "Client Configuration" below).

Usage

As MCP Server (stdio)

python -m camoufox_reverse_mcp

With options:

python -m camoufox_reverse_mcp \
  --proxy http://127.0.0.1:7890 \
  --geoip \
  --humanize \
  --os windows
