notes:
- Every tool carries a complete JSON Schema 2020-12 inputSchema; the verbatim tools/list result is saved
  at mcp/dolls-kill-mcp-tools.json (95KB) and is the authoritative input contract, standing in for an
  OpenAPI this provider does not publish.
- 'Money is expressed as an integer in ISO 4217 minor units paired with a currency code — {"amount": 2500,
  "currency": "USD"} is $25.00 — stated in every price-bearing tool description.'
- The /.well-known/ucp discovery document advertises the service endpoint as https://dolls-test.myshopify.com/api/ucp/mcp,
  the store's myshopify.com hostname, rather than the www.dollskill.com host the storefront actually serves
  it from. The www host answers tools/list correctly; the discovery document is the one naming the other
  hostname. Recorded as observed, not corrected.
