Overview

A Python MCP server that forwards tool calls over HTTP to the JADX-AI-MCP plugin running inside jadx-gui. It exposes about 25 tools for fetching class source, smali, manifest and resources, cross-references, comments, renames and debugger state. It runs over stdio or HTTP (default port 8651) and talks to the plugin on port 8650.

Who it is for: Android reverse engineers and security researchers using LLMs with JADX

Strengths

  • Covers class source, smali, manifest components, resources and xrefs, with pagination
  • Can write back to JADX: rename variables, add and list comments
  • Exposes jadx debugger stack frames, threads and variables to the model
  • Includes an example adapter for OpenAI-compatible endpoints such as Ollama and LiteLLM

Weaknesses

  • Needs the separate JADX-AI-MCP plugin and a running jadx-gui to work
  • Tested only on Claude Desktop, per the README
  • HTTP mode has no authentication or TLS; remote binding needs a tunnel or firewall
  • Docker support and Hermes (React Native) support are unchecked on the roadmap

What it needs

  • no GPU
  • Needs JADX-AI-MCP plugin, jadx-gui, Java 11+, Python 3.10+, uv
  • Models: Claude Desktop, OpenAI-compatible APIs via example client
  • port 8651
