What is Jadx MCP Plugin?

This plugin connects Jadx (an Android decompiler) with Claude AI through MCP, allowing you to use natural language to navigate and analyze decompiled Android app code. It acts as a bridge between technical reverse engineering tools and conversational AI assistance.

How does it work?

The Java plugin exposes Jadx's decompiler API over HTTP, while a Python adapter translates between MCP protocol and the plugin. This lets Claude directly query and analyze Android app code in real-time during your conversations.

When should I use it?

Ideal for: 1) Security researchers analyzing suspicious Android apps 2) Developers learning from decompiled code 3) Anyone who wants AI assistance while reverse engineering

Key Features

Class NavigationBrowse and search all decompiled Java classes in the target APK/DEX file

Source InspectionView complete decompiled source code of any class directly in Claude

Method AnalysisExamine individual methods including their implementation code

Field InspectionView all class fields and their properties

Pros and Cons

Advantages

Natural language interface for reverse engineering

Real-time interaction with decompiled code

No need to manually browse through thousands of classes

Combines Jadx's accuracy with Claude's analysis capabilities

Limitations

Requires both Jadx and Claude to be running

Limited to Java/Android reverse engineering

Initial setup requires technical configuration

Setup and Usage

Install the plugin

Download the plugin JAR from releases and install it in Jadx either via GUI or CLI

Configure Claude

Add the MCP server configuration to Claude's settings file as shown in the examples

Load your APK

Open your target Android file in Jadx as you normally would

Start analyzing

Ask Claude to examine the code using natural language commands

Example Use Cases

Finding Cryptographic OperationsLocate all cryptographic functions in an app to assess security

Analyzing Network CommunicationExamine how an app communicates with its servers

Frequently Asked Questions

🚀 🛠️ Jadx MCP 插件 —— 通過 MCP 實現 Claude 對 Jadx 的反編譯訪問

本項目是一個基於 Java 編寫的 Jadx 插件。它藉助 Jadx API 提供 HTTP 接口服務，讓 Claude 這類工具能通過模型上下文協議 (MCP) 實現即時交互。同時，一個輕量級的 FastMCP 適配器使用 Python 作為橋樑，連接 Claude 和該插件，使智能導航和自動化反編譯工作流程成為可能，非常適合用於 AI 輔助的 Android 應用安全分析。

🚀 快速開始

安裝步驟

克隆倉庫並創建虛擬環境

# 克隆此倉庫
git clone https://github.com/mobilehackinglab/jadx-mcp-plugin.git
cd jadx-mcp-plugin

# 創建並激活虛擬環境
python3 -m venv venv

# 激活：
source venv/bin/activate      # Linux/Mac
.\venv\Scripts\activate       # Windows

安裝 Python 依賴項

pip install -r requirements.txt

集成 Claude MCP 客戶端工具配置

要在 Claude Desktop 中使用此適配器，請轉到 File -> Settings -> Developer -> Edit Config -> claude_desktop_config.json，並添加一個指向 Python 虛擬環境的 MCP 服務器設置（以避免依賴問題），然後指定完整的適配器路徑，如下示例所示：

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": "/home/user/jadx-mcp-plugin/venv/bin/python",
      "args": ["python", "-m", "fastmcp_adapter"]
    }
  }
}

配置完成後，確保 Jadx 已經啟動並運行。

使用流程

啟動 Jadx：首先打開 Jadx 並加載目標文件。
啟動 Claude：在另一個終端中啟動 Claude，並連接到 Jadx 的 MCP 服務器。
使用工具：通過 Claude 提供的 MCP 接口調用反編譯功能。
