REA (Reverse Engineer Anything)
🎁FREEGitHub
REA (Reverse Engineer Anything) is an open-source MCP server + CLI that lets AI coding agents (Claude Code, Cursor, Codex, Gemini CLI, etc.) reverse-engineer software without source code — from high-level app behavior down to native binaries, Electron apps, .NET assemblies, Android APKs, websites, and runtime behavior.
✨Key Features
- ▸One unified interface: Connects your AI agent to professional reverse-engineering tools (Ghidra, Hopper, IDA, JADX, browser instrumentation, Frida, etc.) through a single MCP server.
- ▸Local analysis: Everything runs on your machine; results include evidence, limitations, and unknowns.
- ▸Broad coverage: Native binaries (pseudocode, assembly, strings, symbols), JavaScript/Electron apps, .NET, Android packages, websites, firmware, packet captures, and more.
- ▸Easy setup: One command (npx rea-agents setup) registers it with supported agents and installs workflow instructions.
- ▸Evidence-backed: Returns structured findings with the actual evidence so the agent can explain or recreate features accurately.
- ▸Extremely popular: Went viral in October 2026, reaching hundreds of thousands of GitHub stars in a short time.
- ▸MIT licensed: Free and open-source (third-party engines like IDA/Hopper require their own licenses if used).
