IDA Auto MCP

English | 中文


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

  • 55 Analysis Tools — Decompile, disassemble, xrefs, strings, imports, types, search, rename, patching, 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 .

Quick Start

Codex (~/.codex/config.toml)

Codex reads MCP server settings from ~/.codex/config.toml (or from .codex/config.toml in a trusted project). Add:

[mcp_servers.ida-auto-mcp]
command = "python"
args = ["-m", "ida_auto_mcp"]
startup_timeout_sec = 30
tool_timeout_sec = 600

[mcp_servers.ida-auto-mcp.env]
IDADIR = "C:/Program Files/IDA Pro"

You can register the same server with the Codex CLI instead:

codex mcp add ida-auto-mcp --env "IDADIR=C:/Program Files/IDA Pro" -- python -m ida_auto_mcp
codex mcp list

Replace the IDA path with the installation path on your machine. If Codex cannot find python, set command to the Python executable's absolute path, for example C:/Python310/python.exe. Start a new Codex session after changing the configuration; restart the desktop app or IDE extension when using those clients. See the Codex MCP documentation for additional configuration options.

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

  • 55 个分析工具 — 反编译、反汇编、交叉引用、字符串、导入表、类型系统、搜索、重命名、补丁等

  • 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 .

快速开始

Codex 配置 (~/.codex/config.toml)

Codex 从 ~/.codex/config.toml 读取 MCP 服务器配置;也可以在受信任的项目中使用 项目级 .codex/config.toml。添加以下内容:

[mcp_servers.ida-auto-mcp]
command = "python"
args = ["-m", "ida_auto_mcp"]
startup_timeout_sec = 30
tool_timeout_sec = 600

[mcp_servers.ida-auto-mcp.env]
IDADIR = "C:/Program Files/IDA Pro"

也可以使用 Codex CLI 注册相同的服务器:

codex mcp add ida-auto-mcp --env "IDADIR=C:/Program Files/IDA Pro" -- python -m ida_auto_mcp
codex mcp list

请将 IDA 路径替换为本机的实际安装路径。如果 Codex 找不到 python,请将 command 改为 Python 可执行文件的绝对路径,例如 C:/Python310/python.exe。 修改配置后请新建 Codex 会话;使用桌面应用或 IDE 扩展时,请重启对应客户端。 更多配置选项请参阅 Codex MCP 官方文档
