David Protein

aid: david-protein
name: David Protein
description: 'David is a New York nutrition company founded in 2023 by RXBAR co-founder Peter Rahal, selling high-protein
  bars (28g protein, 150 calories, 0g sugar), the Bronze and Gold bar lines, and protein ice cream pints direct-to-consumer,
  through wholesale, and in retail. David runs no developer program and publishes no OpenAPI, but its Shopify-hosted storefront
  at davidprotein.com serves a complete agent-commerce surface from its own hostnames: an agents.md / llms.txt instruction
  document, a Universal Commerce Protocol (UCP) merchant profile at /.well-known/ucp, OAuth 2.0 and OpenID Connect discovery
  documents, and three live Model Context Protocol servers covering catalog search, product lookup, cart, checkout, shop policy
  Q&A, order status and returns.'

  description: 'The Shopify storefront MCP server David serves at davidprotein.com/api/mcp, declared in the storefront page
    as window.Shopify.MCP.mcpEndpoint and mirrored into the browser through the WebMCP adapter. Five tools: search_catalog,

    anonymously on probe; responses declare the UCP catalog-search capability.'

  description: 'The unauthenticated read-only JSON surface David documents in agents.md for agents that only need to browse:
    /products.json and /collections.json store-wide, /products/{handle}.json per product, /collections/{handle}/products.json
    per collection, and /search?q={query}&type=product. Thirty products were returned on probe. No OpenAPI describes it; the
    contract is the agents.md endpoint list.'

  x-base-note: 'repair-api-bases flags this baseURL as a marketing base because it is the site root. It is correct as written
    and was left alone: David serves these JSON paths from the storefront origin itself (/products.json returned 200 with
    30 products on probe), so the origin is the API host. There is no separate api.davidprotein.com.'
