# How to Use REA GitHub to Reverse Engineer Anything in Claude Code

A 16-minute YouTube walkthrough of REA (Reverse Engineer Anything) showing how to install the REA MCP server, connect it to Claude Code, Codex and Cursor, and use it to read websites, desktop apps and mobile UI in order to rebuild them as your own clean apps. The author links the MIT-licensed REA repository and states that only apps you own or that are open-source should be reverse engineered.

## Description

The video is a step-by-step tutorial on using REA, the open-source MCP tool for reverse engineering, together with Claude Code. It covers installing REA and wiring it into Claude Code, Codex and Cursor; using the REA MCP server to inspect websites, desktop applications and mobile UI; and the author's experience rebuilding three real workflows as clean, ownable apps without starter templates. It also discusses cost, limits and what should not be cloned, and includes a disclaimer to only reverse engineer apps and sites you own or that are open-source, producing inspired clean versions rather than copying proprietary code or assets. Links: REA GitHub (MIT) https://github.com/morluto/rea and https://claude.ai.
