# JADX (Java Decompiler)

> Use this tool when you need to decompile Java bytecode or Android applications for reverse engineering, security analysis, or development purposes. It provides AI assistants with access to fetch and analyze class code, search methods, and retrieve Java and Smali representations of decompiled code through HTTP endpoints. Ideal for security researchers, app developers, and reverse engineers requiring AI-driven insights into compiled Java code.

## Description

JADX-MCP-Server is a FastMCP implementation that provides AI assistants with access to JADX-GUI, a popular Java decompiler tool. This server enables reverse engineering workflows by exposing tools to fetch current class code, retrieve selected text, search for methods across classes, and access both Java and Smali representations of decompiled code. The implementation communicates with a locally running JADX-GUI plugin via HTTP endpoints, allowing AI assistants to analyze Android applications or Java bytecode without direct GUI interaction. It's particularly useful for security researchers, app developers, and reverse engineers who need AI assistance when examining compiled Java code.
