Open Brain is an MCP (Model Context Protocol) server by bobby-cell-commits in the Knowledge & Memory category. Graph-structured MCP memory server. 37.2% LongMemEval. Auto dedup, themes, decay, synthesis.

How do I connect Open Brain to Claude, Cursor, or another MCP client?

Open Brain is a remote MCP server — add its endpoint (https://{supabase_project_ref}.supabase.co/functions/v1/open-brain-mcp/mcp) to your client's MCP configuration (for example with "claude mcp add", or under "mcpServers" in Cursor's mcp.json) and restart the client.

Is Open Brain open source?

Yes — the source code is public at github.com/bobby-cell-commits/open-brain-server, with 9 GitHub stars.

Can AI agents pay to use Open Brain?

Not yet through Loomal — Open Brain is listed as a free directory entry. If its maintainer verifies ownership, they can set per-call USDC pricing that agents pay over x402, with settlement on Base.
