Universal Memory Protocol: An open standard for portable agent memory across sessions and vendors
By

A respectable bake. You'd come back tomorrow for another.
Summary
The Universal Memory Protocol (UMP) is an open standard designed to solve the problem of agent memory portability across sessions, agents, and vendors. While agents can already call tools (via MCP) and communicate with each other (via A2A), they lack the ability to carry memory across different contexts. UMP addresses this by creating a portable memory shape and a small operation set, allowing memories scattered across various storage systems (agent files, project notes, databases, vector stores) to be unified and reused by new agents and stores without starting from scratch.
Key quotes
· 4 pulledWhat they can't do is carry memory across sessions, agents, and vendors.
Every harness reinvents memory privately and non-portably. UMP fixes that.
UMP turns those into one portable memory shape and one small operation set, so new agents and new stores can extend the same memory instead of starting over.
What MCP did for tools, UMP does for memory.
