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

- What you can do
- Search a curated brain for passages on growth, distribution, pricing and building a business, each returned with its source link and date
- List the talks, interviews, essays and post collections that make up a brain
- Use the combined endpoint to list available brains and search across them
- Ask questions in the style of a specific person, such as how one founder would price a product
- When to use it
- Useful when you want startup, marketing or pricing advice grounded in a named founder's or investor's own public material, with citations back to the original source, rather than generic model output.
- Requirements
- A remote MCP endpoint at mcp.brains.ceo, added as a custom connector in clients such as Claude, Cursor, ChatGPT or Codex. Sign-in is required via OAuth: an email address plus a 6-digit code sent by email. No API keys or environment variables are declared.
Installation
In SourceWeft
- Open The Brains in the dashboard and add it to a workspace.
- Connect the required credentials. They are stored privately and never shown on public pages.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.VicPitic%2Fthe-brains/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

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.

[The Brains directory]Use a brain in 30 seconds
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).
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?"

How it works
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.
Steps 2, 4, 5 and 7 run on headless Claude Code (claude -p), so they use a Claude subscription instead of API credits. The first 10 brains cost about $3.50 in total in scraping fees.
Architecture
server/is one Express app (TypeScript, run withtsx) that serves:- the website (
web/) - every brain as a stateless Streamable HTTP MCP endpoint at
/<slug>/mcp - OAuth 2.1 with dynamic client registration, where sign-in is email plus a 6-digit code (
server/oauth.ts) - usage tracking and a password-protected
/adminwith an email CSV export
- the website (
web/is a no-build vanilla HTML/CSS/JS site: a search-first directory, brain pages with cited principles and sources, and per-client install instructions.pipeline/has the scripts above. They're idempotent: re-running a step skips finished work.data/brains/<slug>/holds each brain's curated, derived content:brain.json,index.json,cards/,notes/andshortlist.json.- External brains are ones people already run themselves, like Nevo David's mcp.nevo.md. They're listed with
node pipeline/external.mjs <slug>frompipeline/external/<slug>.json, and installs go straight to their URL.
Run it yourself
That's enough to browse and use all the brains locally. Without DATABASE_URL, the MCP endpoints are open and nothing is tracked. Add one locally:
To build new brains or turn on sign-in and tracking, copy .env.example to .env.local and fill in what you need. Deployment is a single service plus Postgres. We run the website on Railway and the same service on Manufact for the MCP host (mcp.brains.ceo), with BEHIND_MCP_GATEWAY=true and CLIENT_IP_HEADER=cf-connecting-ip.
