🤖 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.

It is combination of two tools:

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

🤖 What is JADX-MCP-SERVER?

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