  The client-side surface David ships is agent-facing rather than developer-facing: a
  browser-side MCP tool registration and Shopify's hosted checkout wallets. There is no
  embeddable element library for third parties to consume.
families:
- name: WebMCP
  kind: in-page agent tool surface
  loader: https://cdn.shopify.com/storefront/webmcp/webmcp-0.1.0.js
  version: 0.1.0
  registration_api: document.modelContext.registerTool
  gate: >-
    The adapter script is only injected when document.modelContext (or
    navigator.modelContext) exposes registerTool - i.e. when an MCP-aware browser or agent
    is present. A plain browser never loads it.
  declared_config:
    'window.Shopify.MCP.enabled': true
    'window.Shopify.MCP.shop': 1f74d5-3d.myshopify.com
    'window.Shopify.MCP.mcpEndpoint': https://davidprotein.com/api/mcp
  tools:
  - name: search_shop_policies_and_faqs
    required: [query]
    optional: [context]
    description: >-
      Used to get facts about the store's policies, products, or services - return policy,
      shipping policy, phone number, hours of operation.
  note: >-
    This is the one place in the surface where a David-specific tool schema is embedded
    directly in the page rather than served from an endpoint.
- name: Portable wallets / accelerated checkout
  kind: hosted checkout component
  loader: https://davidprotein.com/cdn/shopifycloud/portable-wallets/latest/portable-wallets.en.js
  version: null
  note: >-
    Loaded from a "latest" path with no version pin, so a consumer cannot tell what build
    is running. Buyer-facing only; not an integration surface.
- name: Shop skill
  kind: cross-store agent skill (third party, recommended by David)
  url: https://shop.app/SKILL.md
  vendor: Shopify
  note: >-
    agents.md and robots.txt both push personal-shopping agents to install the Shop skill
    and route purchases through Shop Pay rather than driving David's own storefront.
