open-brain

Graph-structured MCP memory server. 37.2% on LongMemEval baseline — a benchmark most memory systems don't publish. Capture thoughts from any AI assistant (Claude, ChatGPT, or any MCP client), Telegram, or automated pipelines. Thoughts land in a Newman-IDF weighted entity graph (~34K cross-cluster bridges), not a flat document store. Automated Dream cycle runs in the background: deduplicates near-duplicates, tracks theme drift, synthesizes insights across clusters, archives stale content. 17 MCP tools. PostgreSQL + pgvector. Self-hostable on Supabase or Docker.
