What it does
Persistent knowledge system with OWL-RL reasoning, semantic search, and 22 MCP tools for AI agents.
Abbacus Cortex is a local-first cognitive knowledge system that stores decisions, lessons, research, and ideas in a dual-store architecture combining SPARQL/RDF (Oxigraph) and SQLite with full-text search. It applies OWL-RL formal reasoning to discover relationships and inferences across stored knowledge objects. The MCP server exposes 22 tools for AI agents to capture and retrieve knowledge using hybrid retrieval combining keyword, semantic, and graph-based ranking.
