RE-MCP

A multi-backend reverse-engineering [MCP](https://modelcontextprotocol.io/) server. Exposes binary analysis capabilities from [IDA Pro](https://hex-rays.com/ida-pro/) and [Ghidra](https://ghidra-sre.org/) over the Model Context Protocol, letting LLMs drive reverse-engineering tools directly. Supports multiple simultaneous databases through a supervisor/worker architecture.

Both backends are standalone servers, not plugins. They use headless APIs ([idalib](https://docs.hex-rays.com/release-notes/9_0#idalib-ida-as-a-library) for IDA, [pyghidra](https://github.com/NationalSecurityAgency/ghidra/tree/master/Ghidra/Features/PyGhidra) for Ghidra) to run analysis engines without a GUI.

Backends

Backend	Package	Requirements
IDA Pro	`re-mcp-ida`	IDA Pro 9+ with a valid license
Ghidra	`re-mcp-ghidra`	Ghidra 12+, JDK 21+

Both backends share a common tool interface — core analysis tools use the same names, parameters, and response shapes — so LLM workflows are portable across backends. Each backend also has tools for platform-specific features (e.g. IDA: file region mapping, executable rebuilding, IDC evaluation, IDAPython scripting; Ghidra: Function ID analysis, data type archives).

Requirements

• Python 3.12+
• uv package manager (recommended) or pip
• macOS, Windows, or Linux
• At least one supported backend installed on the same machine

Installation

Install individual backend packages directly, or install `re-mcp` and select a backend with `--backend`:

# Individual backend packages (each provides its own CLI)
uv tool install re-mcp-ida
uv tool install re-mcp-ghidra

# Or install the core package and use --backend to select
uv tool install re-mcp --with re-mcp-ida --with re-mcp-ghidra

With pip:

pip install re-mcp-ida        # IDA only
pip install re-mcp-ghidra     # Ghidra only
