Gives Claude durable memory through fact extraction, hybrid search, and a temporal graph stored in SQLite or Postgres. You get tools to store observations, query by semantic similarity or structured filters, and track how facts evolve over time. Built by the JamJet team as part of their agent control plane. Reach for this when your agent needs to remember context across sessions or correlate information it gathered hours or days apart. The temporal graph means you can see not just what the agent knows, but when it learned it and how that knowledge changed. Works over stdio, so it drops into Claude Desktop or any MCP client without extra infrastructure.
