English

Headless IDA Pro MCP server that enables AI agents to automatically open, analyze, and query multiple binary files — no manual IDA GUI interaction required.

Why This Project?

Existing IDA MCP solutions (like ida-pro-mcp) require you to:

  1. Manually open IDA Pro GUI
  2. Manually activate the MCP plugin (Ctrl+Alt+M)
  3. Repeat for every binary you want to analyze

This makes multi-file analysis (e.g., a program with multiple DLLs) painful. IDA Auto MCP solves this by using IDA's headless idalib library, letting AI agents autonomously open and analyze any number of binaries.

Key Features

  • Fully Automatic — AI agents call open_binary("path/to/file.dll") to start analysis, no human in the loop
  • Multi-Binary Sessions — Open multiple binaries simultaneously, switch between them freely
  • Headless — Uses idalib (IDA as a library), no GUI needed
  • 36 Analysis Tools — Decompile, disassemble, xrefs, strings, imports, search, rename, and more
  • MCP Standard — Works with Claude Desktop, Claude Code, and any MCP-compatible client
  • Stdio + HTTP — Stdio transport for MCP clients, HTTP for debugging

Prerequisites

  1. IDA Pro 9.0+ (with valid license)
  2. idapro Python package — shipped with IDA Pro:
    pip install "<IDA_INSTALL_DIR>/idalib/python/idapro-9.0-py3-none-win_amd64.whl"
    
  3. IDADIR — set via environment variable or --ida-dir flag

Installation

git clone https://github.com/mufeng05/ida-auto-mcp.git
cd ida-auto-mcp
pip install -e .

AI: list_functions(filter_str="*LoadPlugin*")  → Finds LoadPlugin function
AI: decompile_function("LoadPlugin")           → Gets pseudocode
AI: open_binary("C:/samples/plugin.dll")       → Opens plugin.dll (new session)
AI: list_exports()                             → Lists DLL exports
AI: decompile_function("PluginInit")           → Decompiles export
AI: switch_binary("<main.exe session id>")     → Switches back to main.exe
AI: get_xrefs_to("0x401000")                  → Checks cross-references

无界面 IDA Pro MCP 服务器,让 AI 智能体自动打开、分析和查询多个二进制文件——无需手动操作 IDA GUI。

为什么做这个项目?

现有的 IDA MCP 方案(如 ida-pro-mcp)需要你:

  1. 手动打开 IDA Pro 界面
  2. 手动启用 MCP 插件(Ctrl+Alt+M)
  3. 每分析一个文件都要重复上述步骤

这对于多文件分析(比如一个包含多个 DLL 的程序)非常不友好。IDA Auto MCP 使用 IDA 的无头分析库 idalib,让 AI 智能体能够自主打开和分析任意数量的二进制文件。

核心特性

  • 全自动 — AI 直接调用 open_binary("path/to/file.dll") 即可开始分析,无需人工干预
  • 多文件会话 — 同时打开多个二进制文件,自由切换
  • 无需 GUI — 使用 idalib(IDA 库模式),不需要打开 IDA 界面
  • 36 个分析工具 — 反编译、反汇编、交叉引用、字符串、导入表、搜索、重命名等
  • MCP 标准协议 — 支持 Claude Desktop、Claude Code 及所有 MCP 兼容客户端
  • 双传输模式 — stdio 模式用于 MCP 客户端,HTTP 模式用于调试

前置要求

  1. IDA Pro 9.0+(需要有效许可证)
  2. idapro Python 包 — IDA Pro 安装目录自带:
    pip install "<IDA安装目录>/idalib/python/idapro-9.0-py3-none-win_amd64.whl"
    
  3. IDADIR — 通过环境变量或 --ida-dir 参数设置 IDA 安装路径

安装

git clone https://github.com/mufeng05/ida-auto-mcp.git
cd ida-auto-mcp
pip install -e .
