How to Set Up and Use IDA MCP Server
The IDA MCP Server Plugin integrates IDA Pro 9.0+ with AI assistants like Claude and Cursor by running a local SSE-based MCP server inside the disassembler. Once installed as an IDA plugin, it automatically starts listening on port 3000 and exposes over 20 reverse-engineering tools — from disassembly and decompilation to cross-reference analysis and data-type extraction. Security researchers and reverse engineers use it to query binary internals in natural language without leaving their AI coding environment.
Prerequisites
- IDA Pro version 9.0 or later (commercial license required)
- Python available in the IDA Pro environment with pip for installing dependencies
- An MCP-compatible client such as Claude Desktop, Cursor, or VS Code with MCP support
- Network access to localhost port 3000 (the server binds to 127.0.0.1:3000)
Install Python dependencies
Clone the repository and install the required Python packages. These are needed for the SSE server that the plugin starts inside IDA Pro.
pip install -r requirements.txtCopy the plugin to IDA Pro's plugins directory
Place the ida-mcp-server.py file into the IDA Pro plugins folder for your operating system. IDA Pro loads all .py files from this directory at startup.
# Windows
copy ida-mcp-server.py "%ProgramFiles%\IDA Pro 9.0\plugins\"
# Linux
cp ida-mcp-server.py ~/.idapro/plugins/
# macOS
cp ida-mcp-server.py ~/Library/Application\ Support/IDA\ Pro/plugins/Open a binary in IDA Pro
Launch IDA Pro and open any binary file for analysis. The MCP server plugin starts automatically as part of IDA's plugin initialization — no manual activation is required.
Configure your MCP client to connect via SSE
Add the IDA Pro MCP server to your client's configuration using the SSE transport type. The server listens on http://127.0.0.1:3000/sse by default.
{
"mcpServers": {
"IDAPro": {
"url": "http://127.0.0.1:3000/sse",
"type": "sse"
}
}
}Use AI assistant to analyze the binary
With the binary open in IDA Pro and the MCP server running, your AI assistant can now call any of the exposed tools to retrieve disassembly, decompiled code, cross-references, imports, exports, and more.
IDA MCP Server Examples
Client configuration (SSE transport)
Add this to your MCP client config file (e.g., mcp.json or claude_desktop_config.json). The server runs inside IDA Pro on port 3000.
{
"mcpServers": {
"IDAPro": {
"url": "http://127.0.0.1:3000/sse",
"type": "sse"
}
}
}Prompts to try
Example queries you can send to your AI assistant once the IDA Pro MCP server is running and a binary is open.
- "Show me the disassembly of the main function"
- "Decompile the function at address 0x401000"
- "What functions call sub_401A30? Show all cross-references to it"
- "List all imported functions and their addresses"
- "Find all strings in the binary that contain 'password'"
- "Get the bytes at offset 0x402050 and explain what instruction this is"Troubleshooting IDA MCP Server
Plugin does not start or port 3000 is not listening after opening IDA Pro
Verify that all Python dependencies from requirements.txt were installed into the same Python environment IDA Pro uses. Check the IDA Pro output window for import errors. Also ensure no other application is using port 3000.
AI client cannot connect to the SSE endpoint
Confirm IDA Pro is open and a binary is loaded — the server only starts after plugin initialization. Try opening http://127.0.0.1:3000/sse in a browser to verify connectivity. Check firewall rules that might block loopback traffic.
IDA Pro 8.x or earlier — plugin fails to load
This plugin requires IDA Pro 9.0 or later due to API changes. Older versions are not supported. Verify your IDA version via Help > About.
