jadx-mcp-server

Overview

This MCP server provides a comprehensive set of tools for Android APK reverse engineering through the MCP protocol. It enables AI assistants to load APKs, decompile code to Java source, inspect classes and methods, extract Android manifest components, analyze resource files, and retrieve bytecode representations. The server is built entirely in Java with no external dependencies, making it highly portable and easy to deploy as a single JAR file. It's particularly useful for security researchers, developers, and analysts who need to programmatically analyze Android applications.
