Agentic commerce is reshaping e-commerce in the same way e-commerce reshaped stores. It’s a big change in how digital retail works. As AI agents start to search, compare, negotiate, and buy on behalf of customers, retailers will depend on new technical standards that let systems and agents talk, verify identity, and transact safely. Four protocols sit at the center of this shift: the Agentic Commerce Protocol (ACP), Agent-to-Agent Protocol (A2A), the Agent Payments Protocol (AP2), and the Model Context Protocol (MCP). Together, they form the infrastructure for autonomous shopping at scale.
