JADX-AI-MCP for Cursor: Setup & Config

What you can do with JADX-AI-MCP in Cursor

Choose it for assistant-assisted Android reverse engineering inside an active JADX session.

• Rename obfuscated symbols during an investigation.
• Inspect manifest entries, resources, and debugger state together.

Before you start: JADX-AI-MCP in Cursor

• Java 11 or newer
• Python 3.10 or newer
• JADX with the JADX-AI-MCP plugin installed
• Companion JADX MCP Server
• uv

This follows the README's Cherry Studio configuration. Replace the directory with the companion server checkout. The plugin and server are separate components; uv venv alone does not start the MCP server.

Troubleshooting JADX-AI-MCP in Cursor

• Cursor must find uv for JADX-AI-MCP. Enable the project/user entry in MCP settings and inspect its tools.
• JADX-AI-MCP uses stdio here: Cursor must keep the configured process running; protocol output belongs on stdout and diagnostics on stderr.
• Known limitation: Requires a plugin plus a separate Python server.
• Known limitation: Remote setups must distinguish the MCP listener from the JADX plugin connection.
• General Cursor troubleshooting lives in the /clients/cursor guide.
