    This is a real, live MCP endpoint served from an Ather-owned host
    (shop.atherenergy.com) and advertised by Ather's own /.well-known/ucp merchant
    profile and /llms.txt. The MCP server itself is provided by the Shopify commerce
    platform rather than written by Ather — the merchant profile, the store catalog,
    the payment handlers and the merchant identity are Ather's; the tool surface and
    its schemas are UCP/Shopify's. It is the ONLY machine-callable API surface
    Ather Energy exposes anywhere. Ather publishes no developer API of its own.

  gate: >-
    The endpoint requires a registered UCP agent profile URI on the request before it
    will answer initialize or tools/list. Anonymous introspection is refused, so the
    real per-tool inputSchema could not be captured. Tool names and descriptions below
    come from Ather's own published /llms.txt and /agents.md; their input contracts are
    defined by the UCP shopping OpenRPC schema referenced in the merchant profile.
