The Brains — Claude Code MCP server: cited founder playbooks
Wires a searchable set of founder and investor talks, essays and posts into your agent. Every hit comes back with its source.
claude mcp add --transport http the-brains https://mcp.brains.ceo/mcpWhat The Brains does
The Brains is an MCP server that searches a person's own material: talks, interviews, essays, posts. Each passage it returns carries a link to the source and a date, so you can check where a claim came from. Useful when you want someone's actual experience with growth, distribution or pricing instead of the model's own guess.
One connector covers the whole directory at https://mcp.brains.ceo/mcp, exposing list_brains, search_brains and list_sources. A single person lives at https://mcp.brains.ceo/<slug>/mcp, for instance https://mcp.brains.ceo/pieter-levels/mcp, with its own search_brain and list_sources. Transport is streamable HTTP. On the first connection the client opens a sign-in: email plus a six-digit code. No password involved.
In Claude the server goes in with claude mcp add --transport http the-brains https://mcp.brains.ceo/mcp, then run /mcp and pick Authenticate. Codex takes codex mcp add the-brains --url https://mcp.brains.ceo/mcp followed by codex mcp login the-brains. Cursor, Windsurf, Cline, Zed and GitHub Copilot use the same URL as a custom MCP server in their config. Skip the sign-in and the tools stay silent, so authenticate before your first query.
