Overview

Description from the maker (original English)

Search cited playbooks from top founders and investors on growth, distribution and pricing.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

Common questions

Is The Brains safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 20 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

The Brains

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


Use a brain in 30 seconds

Every brain is a public MCP URL: https://mcp.brains.ceo/ /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?"*

Roundtables

A roundtable puts a few people on one topic behind one connector, like https://mcp.brains.ceo/pricing-brains/mcp. Browse them at brains.ceo/roundtables; they're defined in data/roundtables.json.

ToolWhat it does
ask_all(question)Gets each person's passages on one question, separately and with sources. Your agent writes the answer
search_brains(query, brain, limit)Searches all of them, or one person
list_sources(brain)Lists everything behind one person
Tools
ToolWhat it does
search_brain(query, limit)Searches the brain and returns passages, each with its source link and date
list_sources()Lists every talk, interview, essay and post collection in the brain
