Universal Memory Protocol – a shared format for agent memory (universalmemoryprotocol.io) AI

Universal Memory Protocol (UMP) proposes a portable, signed, bi-temporal memory format and operation set for AI agents, aiming to standardize how agents carry and extend memory across sessions, agents, and vendors. The article positions UMP as the “third interoperability layer” after MCP (tools) and A2A (agent-to-agent coordination), and describes how it can run over existing transports (e.g., MCP and HTTP) with implementations and import bridges for existing stores like files, SQL, Redis, vector databases, and Recall.
