# This AI Can Reverse Engineer Apps & Websites Without Source Code (REA)

A YouTube walkthrough of REA (Reverse Engineer Anything), an open-source MCP tool that connects AI coding agents to reverse-engineering capabilities. It covers what REA does, how it works with AI agents via MCP, its supported analysis targets, setup, and limitations.

## Description

The video introduces REA (Reverse Engineer Anything), an open-source tool that links AI coding agents to reverse-engineering capabilities through the Model Context Protocol. It explains REA's purpose, how MCP connects agents to tools, investigation of web, JavaScript and desktop apps, native binaries and Android, plus setup with `npx rea-agents setup`. Links include the official repository (github.com/morluto/rea) and the creator's fork, and the video notes that REA supports software investigation rather than recovering original source code.

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.
