Our take

An unusually serious take on agent memory: a Rust server over PostgreSQL with hybrid BM25+vector retrieval, MMR diversification, out-of-distribution abstention, a bitemporal knowledge graph with PageRank and community detection, and an eval harness — 25 tools, all from one prolific solo dev. The caveats are real: you must run your own Postgres, the tool surface is large and idiosyncratically named (cuba_faro, cuba_zafra), and the CC BY-NC license bars commercial use. If those fit, this is one of the most technically dense memory servers in the registry.
