  notes: >-
    Platform-provided Model Context Protocol endpoint for the CandyClub Shopify
    storefront, implementing the Universal Commerce Protocol (UCP) shopping
    service (service id dev.ucp.shopping). tools/list requires an agent profile
    URI handshake (returns error invalid_profile_url without one), so the tool
    list below is transcribed from the documented agent flow in /llms.txt and the
    UCP shopping capability set, not from a live tools/list dump. Checkout requires
    contemporaneous human buyer approval before payment.
