You'd reach for this when you need Claude to remember context across sessions without relying on external databases or cloud services. It's a self-hosted continuity layer that stores conversation state with explicit bounds, so you control memory limits and can recover from crashes. The "restart orientation" means it's designed for agents that stop and start frequently rather than running indefinitely. Think of it as a lightweight checkpoint system you run locally. The streamable HTTP transport makes it straightforward to integrate into existing workflows without heavyweight infrastructure. Useful when you're building agent workflows that need to pick up where they left off but don't warrant standing up Redis or Postgres.
