How to Set Up and Use Jadx AI
JADX-AI-MCP is a plugin and MCP server for the JADX Android decompiler that bridges live decompiled Java source directly to LLMs like Claude. It exposes tools that let an AI assistant read class sources, enumerate methods, extract fields, and fetch Smali bytecode from a running JADX session without copying code manually. Security researchers and mobile app analysts use it to accelerate reverse engineering, detect hardcoded secrets, identify insecure API usage, and deobfuscate code with AI guidance during an active JADX session.
Prerequisites
- JADX decompiler installed and able to open an APK or JAR
- Python 3.x and the uv package manager (curl -LsSf https://astral.sh/uv/install.sh | sh)
- Claude Desktop (or another MCP client) with MCP support enabled
- The jadx-ai-mcp release zip downloaded from the GitHub releases page
- httpx and fastmcp Python packages (installed via uv)
Download the release
Go to https://github.com/zinja-coder/jadx-ai-mcp/releases and download the latest release zip. Extract it — you will find two directories: jadx-ai/ (the JADX plugin) and jadx_mcp_server/ (the MCP server).
Install the JADX plugin
Copy the jadx-ai-plugin<version>.jar file from the jadx-ai/ directory into JADX's plugins folder. Restart JADX. The plugin adds an MCP bridge that the server communicates with over a local HTTP port while JADX is running.
Set up the Python MCP server environment
Navigate into the jadx_mcp_server/ directory, create a virtual environment with uv, and install the required packages.
cd jadx_mcp_server
uv venv
source .venv/bin/activate
uv pip install httpx fastmcpConfigure Claude Desktop
Edit your Claude Desktop config file to register the MCP server. Replace <USERNAME> and <PATH/TO/> with your actual values. On Linux the config is at ~/.config/Claude/claude_desktop_config.json; on macOS at ~/Library/Application Support/Claude/claude_desktop_config.json.
{
"mcpServers": {
"jadx-mcp-server": {
"command": "/home/<USERNAME>/.local/bin/uv",
"args": [
"--directory",
"/home/<USERNAME>/jadx_mcp_server/",
"run",
"jadx_mcp.py"
]
}
}
}Open an APK in JADX and start reversing
Launch JADX and open the target APK or JAR. With the plugin active, the MCP server can now read live decompiled output. Open Claude Desktop and verify the jadx-mcp-server connection is shown as active in the MCP panel.

}
}
}Prompts to try
Open a class in JADX, select it, then ask Claude these questions to leverage the live MCP tools.
- "Explain what the currently selected class does in plain English."
- "Check this class for hardcoded API keys, credentials, or secrets."
- "List all network-related API calls made in this class."
- "Deobfuscate and suggest readable rename suggestions for the methods in this class."
- "Are there any insecure cryptographic usages in the selected method?"
- "Search for all classes that call the method named 'encrypt' and summarize what they pass to it."Troubleshooting Jadx AI
Claude shows the MCP server as connected but tools return empty results
The JADX plugin must be loaded and an APK/JAR must be open in JADX before the MCP server can return data. Ensure the jadx-ai plugin JAR is in the correct plugins folder and JADX was restarted after installation.
uv command not found when Claude Desktop tries to start the server
The uv binary path in the config must be the absolute path returned by 'which uv'. Common values are /home/<user>/.local/bin/uv on Linux or /Users/<user>/.local/bin/uv on macOS. Do not rely on shell PATH expansion in the Claude Desktop config.
httpx or fastmcp import errors when starting jadx_mcp.py
Run 'uv pip install httpx fastmcp' inside the jadx_mcp_server directory after activating the venv with 'source .venv/bin/activate'. The config's --directory flag ensures uv uses this venv automatically.
