# Basic Open Brain Setup

## Prerequisite
Basic [[concept-open-brain-d21]] setup: a working [[entity-supabase-d21]] database paired with a configured [[entity-mcp-d21]] server.

## Why It's Required
The entire video assumes the audience has already watched a previous video and successfully set up the foundational Open Brain. The user must already have:
- A **Supabase database** running.
- An **MCP (Model Context Protocol) server** configured to allow an AI agent to communicate with that database.

Without these, none of the subsequent steps in [[framework-open-brain-build]] (or actions [[action-create-shared-table]], [[action-generate-ui-code]], [[action-deploy-vercel]]) make sense.

## What This Vault Covers Instead
This vault is about adding **visual interfaces** ([[concept-human-door]]) and **new domain extensions** *on top of* an already-running database-to-agent connection. The MCP/Supabase connection itself is treated as a black box that you've already wired up.
