Jadx MCP Plugin tools

This listing does not currently have a tool list to display. This does not mean the server has no tools; check its documentation for supported capabilities.

We auto-extract tools from the README. The maintainer can list them under a ## Tools heading to populate this section.

Overview

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.

Key features of Jadx Mcp Plugin

  • Exposes Jadx API via HTTP for MCP clients
  • Provides seven decompiler tools (list classes, search, get source, etc.)
  • Python FastMCP adapter handles MCP‑to‑HTTP translation
  • Embedded HTTP server responds to /invoke and /tools endpoints
  • Automated plugin installation via Gradle (./gradlew installPlugin)
  • Cross‑platform (Windows, macOS, Linux) with Claude Desktop integration

Use cases of Jadx Mcp Plugin

  • AI‑assisted security analysis of Android APK/DEX files
  • Live extraction of decompiled class names, methods, and fields
  • Automated reverse engineering workflows by chaining MCP tool calls
  • Intelligent navigation of decompiled code without manual UI clicks

Frequently asked questions

1

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.

2

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`.

3

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.

4

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.

5

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.
