# Google's Universal Commerce Protocol

**Entity type:** tool / standard · **Canonical name:** Google's Universal Commerce Protocol

An industry effort by **Google** aimed at standardizing **how AI agents express what they may do, when they must ask for human confirmation, and how consent is enforced across platforms**. In the source it is one example of emerging standards that support [[concept-safe-delegation]] on third-party platforms.

> **Enrichment caveat.** As of available public information, this specific protocol name does **not** correspond to a widely documented, formal public standard — it appears to be an emerging or internal initiative. It is cited alongside [[entity-agentic-commerce-protocol]] and [[entity-anthropic-constitution]]; how these competing efforts converge (or fragment) is an [[question-cross-platform-protocol-adoption|open question]].
