Adobe Commerce still has no AgentCore connector. Use an integration's OAuth credentials against /rest/V1/, not a 4-hour admin password token. Reads first. Refunds stay with a person.

MCP is a tool pipe. The 2025-11-25 spec requires OAuth 2.1 and Protected Resource Metadata on HTTP. A local stdio server must not pretend that flow applies. Tool descriptions are not a permission boundary.

There is no native Shopify AgentCore connector. Pin Admin GraphQL, start with read scopes, and keep write_orders off. Browser-on support turns have run about 3× the platform spend.

Assemble the hold reason, aging, and promise-to-pay. Finance releases the order. The agent does not. The account-manager list still caps at 5 priorities — a hold is one of those 5, not a button.

Tell the shopper whether the order is in the return window and offer an exchange first. Do not buy the label and do not call createRefund. Where-is-my-order is about 18% of tickets; this is the next slice, not a second cashier.

Count sessions, handoffs, writes denied, and one wrong answer. At 50,000 sessions the published AgentCore silhouette is about $791 a month — a bill to plan, not money saved. We are not publishing a containment rate.

Run ten real lookups and three must-escalate cases before anyone outside the team sees the agent. Under 16 out of 30 on readiness, do not add a write. We are not publishing a pass rate from a client store.

Quote the customer's contract price, or say you cannot. A $5,000 auto-issue figure in the field guide is a placeholder, not your cap. A person still sends the quote. The public catalog is not the contract.

Ask for a risk brief, not a purchase order. A sample SKU at 5 days of cover is a fixture, not a client result. A buyer still sends the PO. Auto-send is an unattended purchaser.

A chatbot searches help articles. An agent uses tools and can be stopped. Relabeling search as an agent is how Browser-hot pilots hit ~3× Runtime-shaped spend.

Take the lookup work off the queue. Where-is-my-order is about 18% of tickets. Refunds stay with a person. We are not publishing a tickets-down percentage.
