Real second-hand listings from a Vermont thrift desk. A human can buy on eBay; an AI agent can search the catalog, inspect an item, and signal a buy intent through MCP with x402.
The MCP server is live. Tools: search_items, get_item, buy_intent. The catalog is read-only; purchases complete on eBay.

A buy intent is a signed signal, not a payment. The x402 challenge is served at the item’s buy_intent_url; the seller confirms on eBay.
Every card links to the real eBay listing. Prices are the live asks; condition and photos are the seller’s own.
