I built an AI Second Brain on SurrealDB - and connected it to Claude via MCP

The author built a personal AI knowledge system ('second brain') using SurrealDB that extracts entities, generates embeddings, and stores thoughts as a graph with vector and fulltext search. By exposing it as an MCP server, AI assistants like Claude Code can directly search, add, and manage memories from the terminal. SurrealDB handled graph relations, vector indexes, and fulltext search in a single engine without needing separate databases.
