  Oatside is a Southeast Asian oat milk brand founded in Singapore in 2020 by Benedict Lim,
  operating as one of Asia's only "full-stack" plant-milk companies — it controls sourcing,
  R&D and manufacturing from its own facility in Java, Indonesia, using Australian oats.
  Its barista-oriented range (Barista Blend, Espresso Roast, Caffe Latte, Chocolate,
  Chocolate Malt, Matcha, Caramel Macchiato) is sold through independent cafes and retail
  across Singapore, Hong Kong, Indonesia, Vietnam, Thailand, Cambodia, the Philippines,
  Malaysia, Taiwan, India, the Middle East and Australia. Oatside is a consumer packaged
  goods company and publishes no developer program, but its direct-to-consumer Shopify
  storefront exposes a live, anonymous, agent-callable commerce surface: a Universal
  Commerce Protocol (UCP) merchant profile and an MCP endpoint serving 13 catalog, cart
  and checkout tools, plus a published agents.md and llms.txt.

  description: >-
    The agent-facing commerce surface of Oatside's Singapore direct-to-consumer storefront.
    Implements the Universal Commerce Protocol (UCP) 2026-04-08 over MCP: an anonymous
    tools/list returns 13 tools covering catalog search and lookup, product detail, cart
    create/update/cancel, checkout create/get/update/complete/cancel, and order retrieval.
    The protocol implementation is provided by the Shopify platform and scoped to Oatside's
    own merchant tenant (merchant "Oatside SG", shop_id 57430966333) — Oatside did not
    author the protocol, but the endpoint, catalog, policies and commerce relationship
    are Oatside's and are served from a host Oatside controls.
