Universal Memory Protocol – a shared format for agent memory

Universal Memory Protocol (UMP) standardizes how AI agents store and retrieve memories across different sessions, platforms, and vendors, similar to how MCP standardized tool usage. The protocol uses a portable, signed JSON format with six core operations (recall, remember, revise, forget, get, and optional feedback) that work across existing transports like MCP, HTTP, and TypeScript SDKs, allowing agents to access memories from previously scattered sources like databases, vector stores, and project files.
