Mastercard announced Mastercard Agent Connect on September 9, 2026, a platform that lets merchants, AI agents, digital platforms and payment providers connect and transact through a single integration. Mastercard’s press release says it starts in the United States and will roll out with ecosystem partners.
What changed
Alongside Agent Connect, Mastercard expanded its Agent Suite for Merchants, a set of tools for building agent-powered shopping, making products discoverable to AI agents and completing payments. According to the release, the shopping journey has three steps:
- An agent discovers a merchant’s product catalog.
- The agent recommends products and confirms price, taxes and shipping.
- The purchase is completed with secure payment credentials, authorized by the consumer.
The technology named in the release includes Model Context Protocol (MCP), Anthropic’s commerce agent blueprint using Claude models, Mastercard’s Verifiable Intent framework, and Mastercard Agent Pay for payment authorization. Mastercard also says network-agnostic tokenization is coming later.
The release lists partners including Fiserv, Global Payments, Worldline, Nexi, Moneris, Samsung and Trip.com.
What it means for you
If you run a small shop: your payment provider may soon offer agent sales as a switch rather than a custom build. Mastercard says merchants keep control of pricing, fulfillment and how their brand appears. Ask your processor whether it is an Agent Connect partner and what it charges. Our guide to accepting payments from AI agents without code covers the options available today.
If you shop through an AI assistant: the design keeps you in the loop, since the release describes purchases as consumer-authorized and backed by Verifiable Intent, a record of what you approved. That record matters if an agent buys the wrong item. For how refunds and chargebacks work in that case, see who pays when an agent buys the wrong thing.
