Reverse Engineer Apps In Minutes With REA! | Code Scrapper

REA ("Reverse Engineer Anything") is an open-source MCP server that lets your AI coding agent investigate how software works, across native binaries, JavaScript/Electron apps, .NET assemblies, and websites. In this step-by-step guide I go through the GitHub repo, read the README, run the one-line setup, and open it in Claude Code with an example prompt.

In this video you'll learn: ✅ What REA is and what it connects your agent to ✅ How to find the official REA repo (and avoid look-alike copies) ✅ The quick-start setup: npx rea-agents setup ✅ Supported agents: Claude Code, Codex, Cursor, Gemini CLI, and Grok Build ✅ How optional tools like Hopper, Ghidra, and IDA fit in ✅ An example prompt: "Understand how search works in the Notes app, show me the evidence"
