description: 'Cirkul, Inc. is a Tampa, Florida direct-to-consumer beverage company
  founded in 2016 by Garrett Waggoner and Andy Gay. Cirkul sells a reusable bottle
  system paired with patented flavor cartridges — called Sips — that sit in the bottle
  lid behind a dial, letting a drinker adjust flavor intensity without pre-mixing.
  The cartridge lines include LifeSip, FitSip and GoSip, covering more than 100 zero-sugar,
  zero-calorie flavors spanning fruit blends, iced teas, iced coffees and caffeinated
  and electrolyte formulations. Cirkul does not publish a general-purpose developer
  API or an OpenAPI definition; its machine-readable surface is an agent-commerce one,
  served from its own drinkcirkul.com Shopify storefront: an anonymous Model Context
  Protocol server at /api/mcp, a Universal Commerce Protocol (UCP) merchant profile
  at /.well-known/ucp, a UCP shopping MCP endpoint at /api/ucp/mcp, published agent
  instructions at /agents.md and /llms.txt, and OAuth 2.0 / OpenID Connect discovery
  for the Shopify Customer Account API.'

  description: 'The agent-facing commerce surface Cirkul serves from its own drinkcirkul.com
    host. It comprises an anonymous Model Context Protocol (MCP) server at /api/mcp
    exposing five tools with real JSON Schema inputs (search_catalog, get_cart, update_cart,
    search_shop_policies_and_faqs, get_product_details), a Universal Commerce Protocol
    merchant discovery profile at /.well-known/ucp declaring cart, checkout, fulfillment,
    discount, order and catalog capabilities plus Shop Pay, Google Pay and card payment
    handlers, and a UCP shopping MCP endpoint at /api/ucp/mcp whose tools/list is gated
    behind a UCP agent-profile URI. Read-only catalog JSON (products.json, collection
    products.json) is documented for agents that only need to browse. Checkout explicitly
    requires contemporaneous human buyer approval.'
