Cometeer is a Gloucester, Massachusetts coffee company, founded in 2015 by Matthew Roberts and Douglas Hoon, that brews specialty coffee at high extraction and then flash-freezes it with liquid nitrogen into single-serve capsules shipped direct to consumers by subscription. Coffees are roasted by third-wave partners including Counter Culture, Intelligentsia, Onyx, Square Mile, Equator and George Howell. Cometeer publishes no developer API, but its Shopify-hosted storefront exposes a substantial machine-readable agent surface: an /llms.txt agent instruction set, OpenID Connect and RFC 8414 authorization-server metadata on its own apex host, and a live Universal Commerce Protocol (UCP) merchant profile advertising an MCP endpoint for agent-driven cart, checkout and order flows.
