status: published
note: '1MORE''s US storefront serves a live, anonymous remote MCP endpoint on its own domain. It was discovered
  from https://usa.1more.com/llms.txt, confirmed by the Universal Commerce Protocol merchant profile at
  https://usa.1more.com/.well-known/ucp (merchant_name "1MORE", merchant_origin usa.1more.com, shop id
  11404626), and probed directly: initialize and tools/list both returned HTTP 200 with no credentials.
  The 13 tools below are the verbatim tool names, descriptions and input-schema shapes returned by that
  endpoint; the full response including every JSON Schema 2020-12 inputSchema is saved verbatim to mcp/1more-ucp-tools-list.json.
  The implementation is Shopify''s UCP/MCP stack running under 1MORE''s domain and merchant identity,
  not software 1MORE authored - the endpoint, the catalog it returns and the merchant of record are 1MORE''s.'
deployment:
  mode: remote
  endpoint: https://usa.1more.com/api/ucp/mcp
  auth: none
  verified: probed
  note: 'tools/list and initialize answer anonymously over HTTP POST with Content-Type: application/json.
    No install step, no package, no stdio variant is published. The UCP discovery document also advertises
    the same endpoint on the platform origin https://1moreusa.myshopify.com/api/ucp/mcp. Completing a
    checkout requires contemporaneous buyer approval per the store''s own agents.md; browsing and cart
    operations do not.'
