REA: an open-source MCP tool that lets an AI agent reverse-engineer apps and binaries

REA, short for Reverse Engineer Anything, is an MIT-licensed tool, first published on GitHub in April 2026, that connects an AI coding agent, through MCP, to reverse-engineering tools for native binaries, JavaScript and Electron apps, .NET assemblies and websites. The idea: point your agent at an app whose feature you like, and it inspects the app without source code, explains how the feature works with evidence, and can help build a version for your own project. It also works from the terminal, and analysis runs locally. Its latest release, rea-agents v6.4.0, shipped on 11 October 2026. Native analysis can use an existing Hopper, Ghidra or IDA install. Treat the legal and licensing side carefully: copying a competitor's feature by reverse engineering can raise intellectual property questions depending on what you reproduce.
