Mastercard and agentic commerce: supported protocols (UCP, ACP, MCP, AP2)

Mastercard and agentic commerce

With Agent Pay, Mastercard is building the card-rails version of agentic payment: registered agent credentials, verifiable mandates, auditability — and it sits in both structuring coalitions (UCP and AP2).

What it means for merchants

Nothing for a merchant to integrate directly: these pieces arrive through your payment provider. Worth tracking because they gate autonomous (level 3) card purchasing.

To situate these protocols relative to one another, see the UCP / ACP / MCP / AP2 comparison; to assess your own maturity, the agent-ready checklist.
