Should I block AI agents from my WooCommerce store?
No. Some of those agents are shoppers. Blocking every automated request also blocks the next sale. Label the order first. Block later only if the orders you can see are abuse.
A strange order might be a card test, a scraper, or Claude buying a gift. Those are not the same visitor. A theme script that says “bot” cannot tell them apart, and it never sees the signature header.
What a block would stop
A blanket block on automated requests does not know which of those three it is. It can refuse the next sale along with the scraper. The signature is on the checkout request, which a theme pixel does not see.
What to do with the column
Read the Buyer column for a week. A Human order needs nothing from you. A named agent is a sale with a name on it. Unknown means the plugin will not name the buyer: open the order, read the detail line, and fulfill it or not as you already would.
Agent Stamp does not cancel or refund, and holds or refuses nothing unless you turn on a rule. Before you turn one on, open the Agents tab: many agents are buyers your store stops by accident, at a captcha, a login wall or a firewall. The weekly email goes to the store admin when agents visited or an order that week was not a person. A quiet week means every order looked like a person. The stamp sits on the order you already open.
