jadx-mcp-server

Overview

JADX-MCP-SERVER is a Python-based MCP server that connects to a modified version of jadx-gui via the Model Context Protocol. It provides reverse engineering capabilities by allowing LLMs like Claude to interact with decompiled Android code through various MCP tools. The server facilitates vulnerability analysis, code review, and reverse engineering by exposing methods to fetch class information, analyze manifests, search methods, and debug APKs in real-time.
