What an agent can do here (per published signals)
- Publishes a valid UCP manifest (version 2026-04-08), so UCP-aware agents can discover its services automatically.
- Checkout is declared (payment handlers: com.google.pay).
- Serves JSON at /.well-known/mcp.
- Our homepage check saw a WebMCP hint in the HTML. We do not read or test the tools, and it is not part of the score.
- Provides /llms.txt with guidance for language models.
This lists what the shop advertises in machine-readable form. We do not test purchases, so nothing here guarantees that an automated checkout will succeed.
