AI agents still can’t carry memory across sessions, agents, or vendors — every harness reinvents it privately. The Universal Memory Protocol (UMP) is a bid to fix that the way MCP standardized tools: a transport-neutral protocol for how agents store and recall memory.

## What it standardizes

UMP defines negotiated memory operations over a portable, signed, bi-temporal record — each memory carries provenance and time context, and any compliant agent can read or write it. The point is portability: knowledge that moves with you across sessions and across vendors, instead of being trapped in one app’s backend.

## Bridging what exists

Rather than force everyone to rewrite, UMP keeps existing memory formats in place and ships import bridges. Its ump-import tool reads files like AGENTS.md and CLAUDE.md, turns them into portable UMP drafts as procedural memory, and preserves the source path. Whether a memory standard actually gets adopted is the hard part — MCP worked because the big labs converged on it — but the problem UMP targets is real and unsolved.
