# I Used REA: Reverse Engineer Anything to Analyze a Certain App, and It's Seriously Amazing. For Old Windows Apps, the Analysis Finishes Perfectly First

Impressions of using REA: Reverse Engineer Anything to analyze an old Windows app. After analysis, instructing it to analyze the UI makes it capture all features and even create an HTML screen list.

## Description

I used REA: Reverse Engineer Anything to analyze a certain app, and it's seriously amazing.
For old Windows apps, the analysis finishes perfectly first.
After analysis, when I asked it to analyze the UI, it captures all features and even creates an HTML screen list.
What is this, can MCP really do this much?

## Original README

とあるアプリの解析でREA: Reverse Engineer Anything使ったんだけど、マジで凄え。
古いWindowsアプリならまず解析が完璧に終わる。
解析後、UIの解析をしてほしいってやると、全機能キャプチャ取得してHTMLで画面一覧作るまでやってくれる。
なんかだこれ、MCPでここまでできるのかよ。
