Jadx Mcp Plugin

What is Jadx Mcp Plugin?

Jadx Mcp Plugin is a Java-based Jadx plugin that exposes the Jadx decompiler API over HTTP, enabling live interaction with MCP clients like Claude. A Python FastMCP adapter bridges Claude and the plugin, supporting AI-assisted reverse engineering of Android apps.

How to use Jadx Mcp Plugin?

Clone the repository, create a Python virtual environment, and install dependencies. Configure Claude Desktop’s MCP server to point to the Python executable and adapter script. Open Jadx with the plugin installed, load an APK or DEX file, then Claude will detect the tools. Optionally, specify the HTTP interface via jadx-gui -Pjadx-mcp.http-interface=http://localhost:8085.

FAQ from Jadx Mcp Plugin

What are the prerequisites to use Jadx Mcp Plugin?

You need Java (for Jadx), Python 3, and the Jadx decompiler itself. The plugin JAR must be installed in Jadx’s plugins/ folder.

How do I install the Java plugin?

Use the Gradle task ./gradlew installPlugin (requires Jadx in PATH), or manually place the built JAR from plugin/build/libs/ into ~/.jadx/plugins/ and enable it via jadx plugins --enable jadx-mcp.

Can I change the default HTTP interface?

Yes, launch Jadx with -Pjadx-mcp.http-interface=http://localhost:8085 (or any host/port). Update the corresponding URL in fastmcp_adapter.py to match.

Does the plugin work with other MCP clients besides Claude?

The README explicitly mentions Claude, but the plugin exposes standard MCP tools and endpoints, so it should work with any MCP‑compatible client.

Do I need to open Jadx before starting Claude?

Yes, the Python adapter requires the Jadx plugin server to be running. Make sure Jadx is open and has loaded an APK/DEX before launching Claude.
