# このAIはソースコードなしでアプリとウェブサイトをリバースエンジニアリングできる（REA）

REA（Reverse Engineer Anything）のYouTubeウォークスルー。これは、AIコーディングエージェントをリバースエンジニアリング機能に接続するオープンソースのMCPツールです。REAの機能、MCPを介したAIエージェントとの連携方法、サポートされる分析対象、セットアップ、制限について説明します。

## Description

この動画では、モデルコンテキストプロトコルを通じてAIコーディングエージェントをリバースエンジニアリング機能に接続するオープンソースツール、REA（Reverse Engineer Anything）を紹介します。REAの目的、MCPがエージェントをツールに接続する方法、Web、JavaScript、デスクトップアプリ、ネイティブバイナリ、Androidの調査、および`npx rea-agents setup`によるセットアップについて説明します。リンクには公式リポジトリ（github.com/morluto/rea）と作成者のフォークが含まれ、動画はREAが元のソースコードを復元するのではなく、ソフトウェア調査をサポートすることを指摘しています。

What if AI could help you understand how a website or application works—even when you don't have its source code?

In this video, we're exploring REA (Reverse Engineer Anything)**, an open-source tool that connects AI coding agents to reverse-engineering capabilities through MCP (Model Context Protocol).

We'll look at how REA works, what it can analyze, how it connects with AI coding agents, and how developers can use it to investigate software features instead of relying entirely on guesswork.

Whether you're interested in reverse engineering, AI-assisted development, or understanding how applications work behind the scenes, this video will introduce you to a powerful open-source project.


What you'll learn

- What REA (Reverse Engineer Anything) actually does
- How REA works with AI coding agents and MCP
- Understanding websites, JavaScript, and application behavior
- Exploring REA's supported tools and capabilities
- How to get started with REA
- What reverse engineering can and cannot tell you
