Ahnaf Prio describes agentic commerce as AI assistance across product discovery, decision-making, checkout, loyalty and fulfilment. Early browser-driving agents were slow, brittle and likely to trigger merchant fraud controls, so newer systems expose structured commerce capabilities rather than imitating a shopper through screenshots and form filling.
Ahnaf Prio maps the emerging protocol stack: MCP exposes tools, A2A lets customer and merchant agents communicate, ACP and UCP define competing commerce primitives, and AP2 expresses payment authorization such as spending limits and revocation. Product feeds are sent to large assistant providers in advance so they can index merchant catalogues instead of querying every merchant for every search.
A live bakery-agent demonstration walks through product search, cart creation, checkout state transitions and payment authorization under both UCP and ACP. Ahnaf Prio closes with the operational requirement that retailers build behavioural, protocol-compliance and latency evals, because conversational shopping agents can otherwise leak discounts, answer unrelated requests or fail silently as protocols evolve.
