memharness MCP

A community-driven, SQLite-backed MCP server providing bi-temporal, provenance-carrying long-term memory for AI agents. It supports deterministic storage without model calls, enabling recall ranking, hybrid vector and FTS search, and source-staleness signals. The server allows agents to remember, recall, revise, and query facts with temporal context, all stored locally in a single file without external API dependencies.
