The smartest brains on earth, in an MCP.
Founders, CEOs and investors, each turned into a searchable MCP server built from their talks, essays and posts. Add one to Claude, Cursor, ChatGPT or Codex. Every answer cites its source.
brains.ceo · Request a brain · How it works · Run your own
Every brain is a public MCP URL: https://mcp.brains.ceo/<slug>/mcp. To get every brain behind one connector, use https://mcp.brains.ceo/mcp (tools: list_brains, search_brains, list_sources).
# Claude Code
claude mcp add --transport http levels-brain https://mcp.brains.ceo/pieter-levels/mcp
# then run /mcp and choose Authenticate
# Codex
codex mcp add levels-brain --url https://mcp.brains.ceo/pieter-levels/mcp
codex mcp login levels-brain
In Cursor, Claude.ai / Claude Desktop and ChatGPT, add it as a custom MCP server or connector with the same URL. Each brain page on brains.ceo has one-click buttons and step-by-step instructions for each client.
The first time you connect, your client opens a short sign-in: enter your email and the 6-digit code we send you. It's free, and there are no passwords.
Then just ask: "How would Levels price this?" or "What would Paul Graham say about my idea?"

Missing someone? Request a brain. The most-requested ones get built first.
A brain is a small, curated, cited knowledge base, not an archive of everything someone ever said. Each one holds 15–45 long-form sources and a few hundred hand-picked posts, all filtered to the person's principles on growth, distribution, pricing and building a business.
