We Built
NEXO Brain is an open-source MCP memory server (MIT) that implements the Atkinson-Shiffrin memory model:
- Automatic ingestion from conversations
- Semantic retrieval (768-dim embeddings + BM25 hybrid search)
- Cross-encoder reranking
- Multi-query decomposition for complex questions
- Adaptive Ebbinghaus decay (unique memories protected)
- Dream cycles for overnight consolidation
