description: >-
  Rock The Bells serves a live, anonymously-listable Model Context Protocol server on its own
  storefront host at https://shop.rockthebells.com/api/ucp/mcp. It implements the Universal
  Commerce Protocol (UCP) shopping service, exposing 13 tools that let an agent search the
  Rock The Bells catalog, build a cart, and drive a checkout to completion. The endpoint is
  advertised by the store's own /llms.txt, /agents.md and /robots.txt.

  note: >-
    An unauthenticated POST of {"jsonrpc":"2.0","id":1,"method":"tools/list"} returned HTTP 200 with
    the full 13-tool manifest including complete inputSchema for every tool (52,007 bytes, saved
    verbatim to mcp/rock-the-bells-mcp-tools.json). No API key, OAuth challenge or storefront token
    was required to enumerate the tool surface. Payment completion is a separate matter: the store's
    own agent instructions require contemporaneous human buyer approval before any checkout is
    completed, so `auth: none` describes DISCOVERY, not authorization to transact.

ownership:
  verified: true
  evidence: >-
    The MCP endpoint is served from shop.rockthebells.com, a host Rock The Bells controls (DNS CNAME
    to rock-the-bells.myshopify.com). The store's own Storefront GraphQL API reports
    shop.name = "Rock The Bells" and shop.primaryDomain.url = "https://shop.rockthebells.com", and
    every product in /products.json carries vendor "Rock The Bells". The MCP server itself is
    Shopify-native infrastructure (Shopify implements UCP for every store), so the PROTOCOL and tool
    shapes are Shopify's, while the CATALOG, cart, checkout and order data the tools operate on are
    Rock The Bells'. Recorded here as a real agent surface the company serves, not as a bespoke API
    Rock The Bells engineered.

conventions:
  money: >-
    Prices are integers in the currency's ISO 4217 MINOR units paired with a currency code —
    {"amount": 2500, "currency": "USD"} is $25.00. Stated verbatim in every tool description.
  agent_profile_required: >-
    Every tool requires a `meta.ucp-agent.profile` URI so the store can identify the calling agent.
  buyer_context: Pass context.address_country and context.currency for accurate pricing and availability.
