name: Hint Storefront Agentic Commerce MCP
provider: Hint Inc.
summary: >-
  drinkhint.com serves a live Model Context Protocol endpoint for agent-driven commerce against
  Hint's own product catalog. It is reachable anonymously — an unauthenticated POST of
  {"jsonrpc":"2.0","id":1,"method":"tools/list"} returned HTTP 200 with 13 tools and full
  inputSchema for each on 2026-08-22. The server is provided natively by the Shopify platform
  (serverInfo.name "universal-commerce", version 0.1.0) implementing the Universal Commerce
  Protocol, and is served from Hint's own hosts against Hint's own catalog.
ownership_note: >-
  The endpoint is on Hint's own domain (www.drinkhint.com) and its mirror on the store's Shopify
  tenant (drinkhint.myshopify.com). The UCP merchant profile names merchant "drinkhint.com" with
  Shopify gateway merchant id 1430159418. This is Hint's storefront surface running on
  platform-provided software — the templated/self-hosted case — not a Hint-authored API product,
  and it is not a spec belonging to a different company.

notes:
- Every tool requires a `meta.ucp-agent.profile` URI; calls without one are rejected with JSON-RPC
  error -32001 / invalid_profile_url (observed 2026-08-22, HTTP 422).
- Prices in responses are integers in ISO 4217 minor units paired with a currency code.
- The published agent instructions state checkout must not be completed without explicit,
  contemporaneous buyer approval, and point personal shopping agents at https://shop.app/SKILL.md.
