Persistent memory MCP server. 28 tools, BM25+MMR+OOD retrieval, tamper-evident audit, code graph.

Install

claude mcp add cuba-memorys -- npx -y [email protected]

Requires: DATABASE_URL, CUBA_PROJECT_FILTER, CUBA_SYNC_DIR, CUBA_JUDGE, CUBA_JUEZ_CLI, CUBA_JUEZ_MODEL, ANTHROPIC_API_KEY, CUBA_REM_RELATION_BATCH, CUBA_RERANKER_PATH, CUBA_RERANK_FIXED_SHAPE

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.
