Jadx Ai Mcp 🔌 MCP server Free

What it does

JADX-AI-MCP is a plugin for the JADX Android decompiler that connects it to the Model Context Protocol, giving AI assistants live, structured access to a decompiled APK. Instead of pasting decompiled Java or Smali into a chat window, an agent can query classes, methods, resources and cross-references directly inside JADX-GUI — useful for Android reverse engineering, vulnerability research, and malware or app-behavior analysis.

What is inside / Tools it gives your agent

The plugin ships 20+ MCP tools: fetching and searching classes, methods and fields; extracting Smali code; reading the AndroidManifest and resource files; renaming classes, methods, fields, packages and variables; running paginated cross-reference (xref) lookups; and integrating with JADX's debugger (stack frames, threads, live variables).

Works with

Listed as "*" for any MCP client. The project documents working setups with Claude Desktop, Cherry Studio, LM Studio, and any custom client that speaks MCP over stdio or HTTP.

How to install or connect

Install in one line from inside JADX-GUI's plugin manager: jadx plugins --install "github:zinja-coder:jadx-ai-mcp", or add the plugin JAR manually. A separate Python MCP server component (Python 3.10+, using fastmcp and httpx) needs to run alongside it; the Java side needs JADX itself plus Java 11+.

Maintenance and safety

Apache-2.0 licensed, inheriting JADX's own license. Actively maintained, with 2,800+ GitHub stars. Because it can rename decompiled code and expose full source, treat it like any reverse-engineering tool: only point it at APKs you're authorized to analyze.

Who should use it

Security researchers, malware analysts and Android engineers who want an LLM in the loop while reverse engineering an APK, without manually copying decompiled code back and forth between JADX and a chat window.
