Gives Claude on-device encrypted memory backed by SQLite with vector search, plus agent-to-agent payment rails and credit scoring (FICO 300-850). The SDK defaults to deterministic hash embeddings for speed but supports semantic search via Xenova transformers if you need natural language recall. Memory writes are HMAC-signed for integrity, keys derive from agentId by default, and the included LongMem benchmark lets you test recall at scale (1000+ memories). You'd reach for this when building stateful agents that need to remember context across sessions, transact value with other agents, or prove their identity and payment history. Ships with TypeScript types and stdio transport for MCP.
