REA, an MCP reverse-engineering toolkit for AI agents, rockets to nearly 30k GitHub stars in two days

The open-source project REA (Reverse Engineer Anything) went viral on GitHub between October 8 and 9, bringing a full suite of reverse engineering capabilities to coding agents like Claude Code and Codex. Its star count surged from around 19.5k to roughly 29.7k, making it one of the most-watched open-source AI tools this week. Licensed under MIT, the project is worth tracking for its real-world use in agent security and deep analysis scenarios.

Confirmed

Positioning: use AI agents to reverse engineer any target—even without app source code—covering the full chain from app behavior analysis to native binary disassembly (as relayed by @rohanpaulai and @adnanhashmi)
Form factor and integration: ships an MCP server that plugs into agent tools such as Claude Code / Codex (@rohanpaulai, @adnanhashmi)
License and scale: MIT open source, about 29.7k stars, 3.5k forks, 1618 commits; earlier figures showed 21.1k stars and 2.3k forks (@MatthewBerman, @rohanpaulai repo details)
Star growth: gained 7744 stars in a single day on October 8, bringing the total to about 19.5k (@lxfater)

Timeline

10-08: @lxfater first reported 7744 stars gained that day, with a total of about 19.5k
10-09: @MatthewBerman reported 21.1k stars; the same day @rohanpaulai and @adnanhashmi reported 29.1k–29.7k, meaning the project grew its stars by over 50% in two days

Why it matters

Reverse engineering has traditionally relied on specialized tools like Ghidda/IDA plus human expertise; REA hands this entire workflow to general-purpose coding agents, dramatically lowering the barrier to entry
The MCP form factor means the capability can plug directly into the existing agent ecosystem, and heavy promotion from top tech YouTubers (Matthew Berman, Rohan Paul, etc.) amplified its spread
It has direct application potential in security research, vulnerability analysis, and closed-source software interoperability, while also raising compliance and safety concerns about agents being used to reverse engineer closed-source targets
