Jadx Ai MCP

🚀 Jadx Command-line Tool

Jadx is a command-line tool for decompiling Android APK, DEX, JAR, and CLASS files. It provides a wide range of options to customize the decompilation process.

🚀 Quick Start

usage: jadx [options] <input>
The input can be a .dex, .apk, .jar, .class file, or a directory.

✨ Features

• Comprehensive Input Support: Supports various input file types including .dex, .apk, .jar, .class, and directories.
• Customizable Output: Allows specifying output directories, packing outputs into JAR files, and more.
• Multiple Optimization Options: Offers options to skip unknown files, merge class files, and disable certain features.
• Parallel Decompilation: Supports multi-threaded decompilation for improved efficiency.

📦 Installation

The README does not provide installation steps, so this section is skipped.

💻 Usage Examples

Basic Usage

# Decompile an APK file
jadx -d out --source-only --no-gpl input.apk

# Decompile a DEX file in multi-threaded mode
jadx -p -o output.jar /path/to/dex

# Parse a DEX file and disable optimization
jadx --parse-only --no-optimize --api-level 28 input.dex
