dJEB MCP server

JEB MCP服务器

一个模型上下文协议（MCP）服务器，将Claude Desktop与JEB反编译器连接起来，用于Android APK分析。这种集成使人工智能辅助的逆向工程工作流程直接在Claude中实现。

特性

• 反编译：将DEX中的方法和类分解为Java源代码
• 代码导航：列出类、搜索资源并探索交叉引用
• 批量重命名：批量重命名类、方法、字段和局部变量
• 资源分析：访问AndroidManifest.xml、资源和资产文件
• 参见项：查找对方法、字段和字符串的所有引用
• 类层次结构：探索类实现和继承

建筑

该系统由两部分组成：

1. JEB MCP服务器 (dJEB_mcp_server.py)：作为Jython脚本在JEB内部运行，通过套接字公开JEB的API
2. 桥梁脚本 (jeb_mcp_bridge.py)：通过stdio将Claude Desktop连接到JEB服务器

Claude Desktop  jeb_mcp_bridge.py  (port 8851)  dJEB_mcp_server.py (JEB)

安装

先决条件

• JEB反编译器（许可版本）
• 克劳德桌面

设置

1. 克隆此存储库:

   git clone https://github.com/yourusername/jeb-mcp-server.git
   cd jeb-mcp-server

1. 配置Claude桌面:

编辑您的Claude Desktop MCP配置文件：

- macOS: ~/Library/Application Support/Claude/claude_desktop_config.json - 视窗: %APPDATA%/Claude/claude_desktop_config.json

添加以下配置：

   {
     "mcpServers": {
       "jeb-mcp-server": {
         "command": "python3",
         "args": ["/absolute/path/to/jeb-mcp-server/jeb_mcp_bridge.py"]
       }
     }
   }

1. 在JEB中加载脚本:

- 打开JEB反编译器 - 加载您的目标APK文件 - 运行脚本： File → Scripts → Run Script... → 选择 dJEB_mcp_server.py - 服务器将开始监听端口8851

1. 重新启动克劳德桌面 加载MCP服务器配置

用法

配置后，您可以使用自然语言通过Claude Desktop与JEB进行交互。服务器提供以下工具：

示例提示

以下是您可以在JEB MCP服务器上使用的强大提示：

1.深度链接分析

提示：

Analyze the deep-link handling in this Android application step-by-step.
I want you to:
1. Find all activities that handle intent filters with data schemes
2. For each deep-link handler, trace the URL parsing logic
3. Extract all possible endpoints and their parameters
4. Ignore any analytics or tracking code
5. Create a comprehensive map of all deep-link endpoints with their functionality

Please be thorough and explore all related classes.

2.智能类重命名

提示：

I want to rename the obfuscated class "La/b/c;" and its methods to meaningful names.

Please:
1. Decompile the class and analyze its purpose
2. Find all classes that reference or are referenced by this class
3. Examine the broader context by looking at:
   - Parent classes and interfaces
   - Classes that call its methods
   - Classes instantiated within it
4. Only rename elements you're confident about based on:
   - Method functionality
   - String constants used
   - Android framework patterns
   - Common design patterns
5. Provide the rename mappings with explanations
6. Execute the batch rename operation

Be conservative - only rename what you're certain about.

3.API端点提取

提示：

Extract all REST API endpoints used by this application.

Please:
1. Find all HTTP client usage (Retrofit, OkHttp, HttpURLConnection, etc.)
2. Locate API interface definitions or base URL constants
3. For each endpoint, extract:
   - HTTP method (GET, POST, etc.)
   - Full URL path
   - Request parameters
   - Response handling
4. Group endpoints by feature/module
5. Create an API documentation with examples

Focus on actual API calls, ignore logging or analytics.

4.广播接收机分析

提示：

Analyze all broadcast receivers in this application.

For each receiver:
1. Identify what intents it listens for
2. Explain what actions it performs
3. Check if it's exported and the security implications
4. Find where broadcasts are sent from within the app
5. Map the complete broadcast communication flow

Document any security concerns with exported receivers.

5.交叉引用追踪

遵循执行流程：

"Starting from the MainActivity onCreate method, trace all
method calls related to user login, and map the complete
authentication flow with all classes involved."
