Frida Agent MCP Server

Local setup required. This server has to be cloned and prepared on your machine before you register it in Claude Code.
1

Set the server up locally

Run this once to clone and prepare the server before adding it to Claude Code.

Run in terminal
pip install .
2

Register it in Claude Code

After the local setup is done, run this command to point Claude Code at the built server.

Run in terminal
claude mcp add frida-mcp -- node "<FULL_PATH_TO_FRIDA_MCP>/dist/index.js"

Replace <FULL_PATH_TO_FRIDA_MCP>/dist/index.js with the actual folder you prepared in step 1.

AI-driven Android dynamic analysis tool for automated reverse engineering.

Frida Agent MCP

AI 驱动的 Android 动态分析工具。通过 MCP (Model Context Protocol) 让 AI 直接操控 Frida,实现自动化逆向分析。

AI (Claude) → MCP Server → Frida CLI → zygisk-gadget (手机) → 结果返回

前提条件

  • Python >= 3.10
  • Android 手机已 root,安装 Magisk
  • 安装 zygisk-gadget Magisk 模块(固定端口 14725)
  • ADB 已连接手机

安装

pip install .

安装后运行一键配置(注册 MCP + 安装 Skills):

frida-mcp-setup

或手动配置,在 ~/.claude.json 中添加:

{
  "mcpServers": {
    "frida-agent": {
      "command": "frida-mcp"
    }
  }
}

MCP Tools

工具 说明
connect 建立 ADB 端口转发,连接 zygisk-gadget
list_apps 列出设备上的第三方应用
execute 注入 Frida JS 脚本到前台应用(支持 script 内联 / script_file 文件路径)
spawn_and_inject 杀死 → 重启 → 注入,一步完成(适用于需要启动时 hook 的场景)
get_messages 获取注入脚本的输出(支持分页、自动文件回退)
logcat 查看 Android 日志,排查崩溃原因
launch_app 启动指定应用
kill_app 强制停止指定应用
reconnect 重新建立连接(崩溃后恢复)
detach 断开当前注入会话

Skills(Claude Code 技能)

安装后可在 Claude Code 中使用:

  • /reverse-analyze — 逆向分析与动态 Hook,结合 IDA 静态分析 + Frida 动态验证
  • /trace-vm — VM 保护函数分析,指导人工 trace 并由 AI 分析结果

使用示例

基本 Hook 流程

用户: hook 淘宝的 Cipher.doFinal 看看加密参数

AI 自动执行:
1. connect()                    — 建立连接
2. spawn_and_inject(            — 启动并注入
     "com.taobao.taobao",
     "Java.perform(function() { ... })"
   )
3. 提示用户触发操作              — "请点击登录按钮"
4. get_messages()               — 获取 hook 结果
5. 分析并展示加密参数和返回值

结合 IDA 静态分析

用户: /reverse-analyze 分析 libsgmain.so 中 0x1234 处的函数

AI 自动执行:
1. IDA MCP 反编译目标函数,分析参数和返回值类型
2. 生成 Frida Hook 脚本
3. spawn_and_inject 注入
4. 交叉验证静态分析和动态结果

工作原理

本工具使用 Frida CLI 而非 frida-python API,通过 frida -H 127.0.0.1:14725 -F -l script.js -o output.txt 注入脚本:

  • 脚本中的 send() 调用自动转换为 console.log(JSON.stringify())
  • 所有脚本自动包裹 try-catch 防止注入崩溃
  • 输出通过 -o 标志写入文件,get_messages 时停止 frida 进程以刷新文件
