GrumpyDev MCP is a server that lets AI assistants get code reviews from a simulated grumpy senior developer with 40+ years of experience. Created by Yohan Lasorsa, this tool provides thorough, sarcastic, and slightly condescending feedback on code quality, pointing out mistakes, inefficiencies, and bad practices. The implementation uses GenAIScript to define a review_code tool that accepts code input and returns detailed critiques in a distinctive grumpy tone, making it useful for developers seeking brutally honest feedback on their code.
