⚙️ Jadx MCP Plugin — Decompiler Access for Claude via MCP

This project provides a Jadx plugin written in Java, which exposes the Jadx API over HTTP — enabling live interaction through MCP clients like Claude via the Model Context Protocol (MCP). A lightweight FastMCP adapter in Python acts as a bridge between Claude and the plugin. This enables intelligent navigation and automation of reverse engineering workflows, ideal for AI-assisted security analysis of Android apps.

🧠 Setup Claude MCP CLient Integration

To use this adapter in Claude Desktop, go to File -> Settings -> Developer -> Edit Config -> claude_desktop_config.json and add an MCP server pointing to the Python executable in the venv (to prevent depedency issues) and the full adapter path following below examples:

Windows:

{
"mcpServers": {
"Jadx MCP Server": {
"command": "C:\\Workset\\jadx-mcp-plugin\\venv\\Scripts\\python.exe",
"args": ["C:\\Workset\\jadx-mcp-plugin\\fastmcp_adapter.py"]
}
}
}

MacOS / Linux:

{
"mcpServers": {
"Jadx MCP Server": {
"command": "/Users/yourname/jadx-mcp-plugin/venv/bin/python",
"args": ["/Users/yourname/jadx-mcp-plugin/fastmcp_adapter.py"]
}
}
}

Make sure to restart (Quit) Claude after editing the config. After restart it should look like this:
