REA (Reverse Engineer Anything), a reverse engineering support tool for AI agents released by morluto on GitHub, is rapidly gaining popularity. Its GitHub star count, which stood at 41 on October 2nd, surpassed 300,000 on the 17th, and reached 347,802 by the 21st.
REA is a tool that assists in reverse engineering by examining completed applications and executables to understand their internal processes. It provides analysis capabilities to AI agents via the 'MCP' standard for AI. Even without the original source code, it can investigate how specific functions operate, providing explanations and enabling re-implementation with supporting evidence.
Its targets include PC executables, applications built with JavaScript and Electron, .NET programs, and websites. The official website showcases examples such as investigating why "200 + 10%" equals 220 in the Windows Calculator, and how Notion copies text and HTML.
REA is available for free under the MIT License. The developer requests lawful use, specifically for software owned by the user or targets for which investigation permission has been obtained.
