note: >-
  BestPrice publishes no web components, element library or embeddable dashboard for a website. The
  one client-side UI surface it ships is an MCP Apps card served to the AI HOST rather than to a page,
  and the provider is careful that it is optional: structured content stays authoritative and every
  tool mirrors its full JSON into TextContent for hosts that render neither the card nor
  structuredContent. That is the right default, and it is recorded here because "has an agent UI" and
  "requires an agent UI" are very different postures.

      Hosts that do not render the card lose no information — each tool returns the same bounded JSON
      as TextContent alongside structuredContent.
