  American Eagle Outfitters exposes one live, anonymously reachable MCP endpoint across its
  estate: the Universal Commerce Protocol (UCP) shopping server on www.unsubscribed.com, the
  AEO brand storefront running on Shopify. It answers `initialize` and `tools/list` without
  credentials and returns 13 real tools with full JSON Schema inputs covering catalog search,
  cart, checkout and order lookup. It is a Shopify platform capability served from an
  AEO-controlled hostname, not a server AEO wrote — but it is the surface an agent actually
  reaches when it shops an AEO brand, so it is recorded as present.

    and name "American Eagle Outfitters, Inc., 77 Hot Metal Street, Pittsburgh, Pennsylvania

    one of AEO's five brands and links to www.unsubscribed.com.

  note: >-
    Discovery (initialize, tools/list) is fully anonymous. tools/call, prompts/list and
    resources/list are gated on a UCP agent profile — they return JSON-RPC error -32001
    "UCP discovery failed" / invalid_profile_url until the caller supplies
    meta["ucp-agent"].profile. There is no API key and no OAuth on the discovery path.
