Outer

  description: 'The Universal Commerce Protocol shopping service Outer''s storefront exposes over MCP, advertised in the merchant
    profile at https://liveouter.com/.well-known/ucp. It carries the dev.ucp.shopping service with catalog search and lookup,
    cart, checkout, fulfillment, discount and order capabilities, plus Google Pay, Shopify Card and Shop Pay payment handlers.
    tools/list is not anonymous: the endpoint answers HTTP 422 invalid_profile_url until the calling agent supplies a resolvable
    UCP agent profile URI, so live tool input schemas require a registered agent identity. The tool names recorded in mcp/outer-mcp.yml
    are the ones Outer publishes in its own /llms.txt.'
