IDA Pro MCP Documentation and Utilities

This project provides documentation and utilities for working with IDA Pro through MCP (Machine Code Processor).

This project was a for-fun for myself to learn how to use MCP, it is not meant for real-life use.

⚠️ System Requirements

• IDA Pro installation is required
• Python 3.8 or higher

🔧 Prerequisites

1. IDA Pro Installation
   • Ensure you have a working installation of IDA Pro
   • Set the IDADIR environment variable to point to your IDA Pro installation directory

     # Example (PowerShell):
     $env:IDADIR = "C:Program FilesIDA Pro"
     # or set it permanently through Windows System Properties > Environment Variables
     

📥 Installation

1. Install Poetry (if not already installed)

   (Invoke-WebRequest -Uri https://install.python-poetry.org -UseBasicParsing).Content | py -
   

   OR

   pipx install poetry
   

2. Install Dependencies

   poetry install
   

🚀 Setting up the MCP Server

1. Cursor MCP configuration setup

   "ida-pro-doc": {
      "command": "<venv_python_path>/python.exe",
      "args": [
        "<path_to_project>/server.py"
      ]
    }
   

🔍 Troubleshooting

1. If you encounter issues with MCP server:

   • Ensure IDADIR environment variable is correctly set
   • Verify IDA Pro installation is working properly
   • Check if any antivirus software is blocking the connections

2. Common Issues:

   • “IDADIR not found”: Set the environment variable as shown in Prerequisites
   • Connection refused: Make sure no other instance of MCP server is running
   • Windows only: This project has been tested and is supported only on Windows systems
   • Cursor only: This project has only been tested inside of cursor but should work with other software.

📝 Notes

• The server uses idalib and opening ida pro is not required! (this is supported only after IDA 9.0)
• Always ensure IDA Pro is properly closed before starting the MCP server
• The MCP server needs to be running for any IDA Pro automation scripts to work
• This project is Windows-only at the moment - other operating systems are not supported but should work (with a little tweaking)
• This is a rough stupid implementation but it works for my tests, it allows the LLM to better understand the api of ida-pro it’s accessible to, this will help developing plugins and scripts for ida!
