About Jebmcp
Jebmcp is an MCP server and plugin for JEB Pro that lets clients such as Cline, Cursor and RooCode work with JEB for reverse engineering. It is aimed at reverse engineers and security analysts working with APK files.
Key features
- 01Local MCP server started from within JEB
- 02Integration through a JEB Python script
- 03Configuration examples for Cline, Cursor and RooCode
- 04APK reverse engineering workflow
Use cases
- 01Analyzing the purpose of classes and methods in an APK
- 02Renaming short method names based on analysis results
- 03Supporting vulnerability analysis of Android applications
MCP support
This project is an MCP server that runs inside JEB and listens on http://127.0.0.1:16161, so MCP clients can connect to it.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.
Details
From the project README
A quick-and-dirty MCP server&Plugin for JEB Pro. Tested on Cline & Cursor & RooCode.
Reference: https://github.com/mrexodia/ida-pro-mcp
Installation
Requirements
Python >= 3.11
uv: https://docs.astral.sh/uv/getting-started/installation/
Usage
- COPY the src/jeb_mcp/MCP.py to $JEB_INSTALLATION_DIR/scripts. Make sure the jython file is also present
- Choose and Start the script in JEB GUI (
File->Scripts->Scripts selector...), check for desired output:
[MCP] Plugin loaded
[MCP] Plugin running
[MCP] Server started at http://127.0.0.1:16161
- Add this MCP server's config in cline/cursor/etc, as in the sample
安装
要求：
安装 python3.11及以上版本
安装 uv https://docs.astral.sh/uv/getting-started/installation/
RooCode 使用方法：
- 使用 vscode 打开该工具，此时目录结构如下：
.
├── README.md
├── jeb-mcp
│ ├── pyproject.toml
│ ├── src
│ │ └── jeb_mcp
│ │ ├── MCP.py
│ │ ├── server.py
│ │ └── server_generated.py
│ └── uv.lock
└── sample_cline_mcp_settings.json
- 点击左侧活动栏 rooCode 图标，然后继续点击 RooCode 对话框右上角
...，最后点击编辑项目 MCP 按钮， 会在当前目录下产生一个.roo目录，其中包含mcp.json文件。
- 修改
mcp.json文件为下列内容：
{
"mcpServers": {
"jeb": {
"command": "uv",
"args": ["--directory", "jeb-mcp/src/jeb_mcp", "run", "server.py"],
"timeout": 1800,
"disabled": false,
"autoApprove": [
"ping",
"check_connection",
"get_manifest",
"get_all_exported_activities",
"get_exported_activities_count",
"get_an_exported_activity_by_index",
"get_class_decompiled_code",
"get_method_decompiled_code",
"get_method_overrides",
"get_method_callers",
"get_superclass",
"get_interfaces",
"get_class_methods",
"get_class_fields",
"rename_class_name",
"rename_method_name",
"rename_field_name"
],
"alwaysAllow": [
"check_connection",
"get_class_decompiled_code",
"get_class_fields",
"ping",
"get_manifest",
"get_all_exported_activities",
"get_exported_activities_count",
"get_an_exported_activity_by_index",
"get_method_decompiled_code",
"get_method_callers",
"get_method_overrides",
"get_superclass",
"get_interfaces",
"get_class_methods",
"rename_class_name",
"rename_method_name",
"rename_class_field"
]
}
}
}
此时可以发现 mcp 服务器列表中已经存在 jeb mcp 服务器了。
- 打开 jeb 菜单栏
File->Scripts->Scripts selector...选中当前目录下jeb-mcp/src/jeb_mcp/MCP.py文件， 运行脚本，此时可以在 jeb 的 logger 窗口中看到如下输出：
[MCP] Plugin loaded
[MCP] Plugin running
[MCP] Server started at http://127.0.0.1:16161
- 在 RooCode 对话框中输入下列相应的任务即可，如：
1. 连接MCP JEB
2. 分析D:\xxx.apk 应用的 Lnet/xxx/MainActivity; 类的功能
3. 根据功能重命名所有方法名小于3个字符的名称
4. 如果调用了其他类的方法，分析相应的类功能，并重命名方法名小于3个字符的名称
5. 输出分析过程

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
