# Reverse Engineer Apps In Minutes With REA! | Code Scrapper

A step-by-step YouTube guide to REA, the open-source MCP server for reverse engineering: it walks through the official GitHub repo, the npx rea-agents setup, supported agents (Claude Code, Codex, Cursor, Gemini CLI, Grok Build), optional tools such as Hopper, Ghidra and IDA, and an example prompt for investigating how an app works.

## Description

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"

⚠️ Install REA only from the official repository, website, or npm package. Copied repos and look-alike READMEs are not official downloads.
⚠️ Responsible use: Only analyze software you own or have permission to analyze, and respect licenses, terms of service, and local laws. This video is for educational purposes.
