🤖 What is JADX-MCP-SERVER?

JADX MCP Server is a standalone Python server that interacts with a modified version of jadx-gui (see: jadx-ai-mcp) via MCP (Model Context Protocol). It lets LLMs communicate with the decompiled Android app context live.

🤖 What is JADX-AI-MCP?

JADX-AI-MCP is a plugin for the JADX decompiler that integrates directly with Model Context Protocol (MCP) to provide live reverse engineering support with LLMs like Claude.

Think: "Decompile → Context-Aware Code Review → AI Recommendations" — all in real time.

Watch the demo!

It is combination of two tools:

1. JADX-AI-MCP
2. JADX MCP SERVER

🛣️ Future Roadmap

• Add Support for apktool

• Add support for hermes code (ReactNative Application)

• Add more useful MCP Tools

• Make LLM be able to modify code on JADX

• Add prompts templates, give llm access to Android APK Files as Resources

• END-GOAL : Make all android reverse engineering and APK modification tools Connect with single MCP server to make reverse engineering apk files as easy as possible purely from vibes.

🙏 Credits

This project is a plugin for JADX, an amazing open-source Android decompiler created and maintained by @skylot. All core decompilation logic belongs to them. I have only extended it to support my MCP server with AI capabilities.

📎 Original README (JADX)

The original README.md from jadx is included here in this repository for reference and credit.

This MCP server is made possible by the extensibility of JADX-GUI and the amazing Android reverse engineering community.

Also huge thanks to @aaddrick for developing Claude desktop for Debian based linux.

And in last thanks to @anthropics for developing the Model Context Protocol and @FastMCP team
