How to Set Up and Use Open Brain Template

Open Brain Template is an open-source persistent memory system for AI agents, built on Supabase (PostgreSQL + pgvector), Vercel, and optionally Mem0, that gives Claude Code, Claude Desktop, Cursor, and ChatGPT a shared long-term memory store across all sessions. It exposes six MCP tools — `remember`, `recall`, `memory_query`, `recent_memories`, `forget`, and `memory_stats` — and ships with a visual dashboard for browsing and managing stored memories. The optional SessionStart hook auto-injects the most recent memories at the start of every Claude session, ensuring continuity without manual prompting.

Prerequisites

  • A Supabase account with a new project created (free tier works) — for the PostgreSQL + pgvector backend
  • A Vercel account for hosting the dashboard frontend
  • Google OAuth configured in Supabase Auth (the dashboard uses Google sign-in)
  • Node.js and git for local development
  • An MCP-compatible client such as Claude Desktop, Claude Code, or Cursor
1

Create a Supabase project

Go to supabase.com and create a new project. Note your project URL and anon key from the project settings — you will need them in the next step.

2

Clone the repository

Clone the Open Brain Template repository to your local machine.

git clone https://github.com/wefilmshit/open-brain-template.git
cd open-brain-template
3

Configure Supabase credentials in index.html

Open `index.html` and replace the placeholder values with your Supabase project URL and anon key. Also add your email address to the `ALLOWED_EMAILS` array to restrict dashboard access.

# In index.html, update these values:
# YOUR_SUPABASE_URL  → your project URL (e.g. https://xyz.supabase.co)
# YOUR_SUPABASE_ANON_KEY → your project anon key
# ALLOWED_EMAILS → ['[email protected]']
4

Deploy the dashboard to Vercel

Deploy the repository to Vercel using the Vercel CLI or by importing the repository via the Vercel web interface. The dashboard will be available at your Vercel deployment URL.

npx vercel deploy
5

Configure the MCP server in your client

Add the Open Brain MCP server to your MCP client configuration. The server connects to Supabase using your project URL and anon key as environment variables.

{
  "mcpServers": {
    "open-brain": {
      "command": "npx",
      "args": ["open-brain-template"],
      "env": {
        "SUPABASE_URL": "https://your-project.supabase.co",
        "SUPABASE_ANON_KEY": "your-anon-key"
      }
    }
  }
}
6

Optional: Enable the SessionStart hook

To auto-load recent memories at the start of every Claude session, configure the SessionStart hook in `~/.claude/settings.json`. This calls the `recent_memories` tool automatically when a new session begins.

# In ~/.claude/settings.json, add the SessionStart hook
# per the instructions in the repo's CLAUDE.md file

Open Brain Template Examples

Client configuration

Claude Desktop configuration for Open Brain Template with Supabase credentials.

{
  "mcpServers": {
    "open-brain": {
      "command": "npx",
      "args": ["open-brain-template"],
      "env": {
        "SUPABASE_URL": "https://your-project.supabase.co",
        "SUPABASE_ANON_KEY": "your-supabase-anon-key"
      }
    }
  }
}

Prompts to try

Example prompts that use the six memory tools to store, retrieve, and manage persistent knowledge.

- "Remember that we decided to use PostgreSQL for the user service because of its JSONB support"
- "What do you remember about the authentication module from our previous sessions?"
- "Query my memories for anything related to the API rate limiting discussion"
- "Show me the 10 most recent memories you've stored"
- "How many memories are stored in my brain and what categories are most common?"
- "Forget the memory about using Redis for session storage — we changed that decision"

Troubleshooting Open Brain Template

Dashboard shows a blank page or authentication error after Vercel deployment

Ensure your email address is in the `ALLOWED_EMAILS` array in `index.html` before deploying. Also verify that Google OAuth is enabled in your Supabase Auth settings under Authentication > Providers.

recall or memory_query returns no results even after storing memories

pgvector must be enabled in your Supabase project. Go to Database > Extensions in the Supabase dashboard and enable the `vector` extension. Then re-run any database migrations referenced in the repo.

MCP server fails to start with SUPABASE_URL not set error

Ensure both `SUPABASE_URL` and `SUPABASE_ANON_KEY` are set in the `env` block of your MCP client configuration. These are required for every connection — the server has no fallback values.
