This is a personal data persistence layer for AI assistants. It lets Claude store and retrieve structured data, maintain semantic memory across conversations, and save reusable skills or workflows in a private vault you control. Think of it as giving your AI a long-term memory bank where it can stash information about your preferences, project context, or custom procedures, then pull them back up in future sessions. You'd reach for this when you want continuity between chats without manually re-explaining context every time, or when you need Claude to remember specific data structures and operations you've taught it. The streamable HTTP transport makes it accessible as a remote service rather than running locally.
