description: >-
  Supergoop! publishes no numeric rate limits of its own. What it does emit is a
  real runtime cost signal on both machine surfaces, captured here from live
  responses, plus a prose back-off instruction in its agent document.
limit_count: 0
limit_count_note: >-
  No published quota, window, burst or per-key limit exists anywhere on
  supergoop.com. limit_count is an honest zero; the headers below are the
  runtime signal an agent actually gets.

      https://supergoop.com/llms.txt — "The MCP endpoint is rate-limited per IP.
      Back off on 429 responses."
    response_headers:
      - {name: shopify-complexity-score, observed: '360', meaning: Cost of the request in legacy complexity points.}
      - {name: shopify-complexity-score-v2, observed: '36', meaning: Cost of the request under the v2 complexity model.}
      - {name: 'x-shopify-ucp-mcp-api-version', observed: '2026-08-25', meaning: Negotiated UCP protocol version (not a limit, recorded for completeness).}
    standard_headers: none
    standard_headers_note: >-
      No RateLimit-*, X-RateLimit-* or Retry-After header was returned on a 200.
      An agent can read cost but cannot read remaining budget or reset time.

      meaning: >-
        Query cost is returned inline in the GraphQL response envelope rather
        than in a header. Observed on every probe.
