Let AI agents search a store, build carts, and prep checkout
Documented elsewhere: the post is a pitch rather than a walkthrough: The builder says they can make ecommerce sites “agentic commerce ready” so ChatGPT users can discover products through Vendable. The concrete mechanics come from a seller’s comment, which says their store exposes its own MCP server so Claude or ChatGPT agents can search the catalog, create a custom tee, build a cart, and start checkout, with payment completed on the store site. The thread gives no performance numbers or rollout results.

Why it matters
Comparing products, prices and delivery options is slow work for a human and fast work for an agent. Cases like this show agents doing the legwork before anything gets bought. It is one of 65 sightings filed under Shopping on Agent Sightings (number 63 by interest), and one of 91 involving Claude.
How you could try it
Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Claude or any similar agent and adjust the details to your situation.
Shopping task: let AI agents search a store, build carts, and prep checkout. Collect order/policy details, prepare exact steps, and pause before submit or payment.
Tip: Ask the agent to stop before checkout and show you the final basket, price and delivery date before you confirm.
