Open-source Warren Buffett Brain: an MCP server that makes AI challenge your investment thesis
ValuEdge · reddit · 2026-11-04
Inspired by Buffett's $433M shoe-company purchase that cost shareholders $3.5B, a developer open-sourced Warren Buffett Brain: a research library and AI skill built around Berkshire's real decisions, principles and mistakes. It includes 55 original research notes, 8 case studies, source links and a local MCP server, aiming to make AI question your investment thesis instead of confidently endorsing every stock. MIT-licensed, usable now via a ChatGPT prompt.
