  mcp/l-nutra-prolonlife-ucp-tools-list.json, mcp/l-nutra-prolonlife-storefront-tools-list.json and
  the read-only REST surface documented in llms/l-nutra-llms.txt
description: >-
  L-Nutra publishes no OpenAPI, so this crosswalk binds the two divergent MCP surfaces to each other
  and to the read-only JSON endpoints the store's own llms.txt documents. The three surfaces are
  overlapping but not identical: the UCP endpoint is the only one that can transact, the Storefront
  MCP endpoint is the only one that can answer policy and FAQ questions, and the documented
  storefront JSON paths are the only surface reachable with a plain GET. No OpenAPI operationIds
  exist, so `rest:` rows carry the documented HTTP path instead and confidence is set accordingly.

    note: >-
      Returns only search_shop_policies_and_faqs on l-nutrahealth.com and l-nutraprofessional.com —
      the catalog and cart tools are enabled on prolonlife.com alone.

    source: https://prolonlife.com/llms.txt
    gated: false
    note: Read-only Shopify storefront JSON paths, no authentication required.
crosswalk:
- tool: search_catalog
  category: catalog
  rest: ['GET /search?q={query}&type=product', 'GET /collections/all']
  binding: semantic
  confidence: medium
  note: >-
    Both return products matching a query, but the MCP tool accepts natural-language intent and
    structured filters the storefront search URL does not expose.
- tool: get_product
  category: catalog
  rest: ['GET /products/{handle}.json']
  binding: semantic
  confidence: medium
  note: >-
    The MCP tool resolves by product or variant identifier and returns real-time availability and
    exact pricing; the JSON path resolves by handle only.
- tool: lookup_catalog
  category: catalog
  rest: ['GET /collections/{handle}/products.json']
  binding: partial
  confidence: low
  note: Batch identifier resolution has no direct REST equivalent; the collection JSON is the closest read.
mcp_only:
- tool: create_cart
  reason: No anonymous REST cart-creation endpoint is documented on the storefront.
- tool: get_cart
  reason: Cart state is only reachable through MCP or a browser session.
- tool: update_cart
  reason: No documented REST equivalent.
- tool: cancel_cart
  reason: No documented REST equivalent.
- tool: create_checkout
  reason: Checkout is UCP-only; the store publishes no REST checkout API.
- tool: get_checkout
  reason: UCP-only.
- tool: update_checkout
  reason: UCP-only.
- tool: complete_checkout
  reason: >-
    UCP-only, and the only write in the whole surface that requires an idempotency key. Payment
    completion additionally requires contemporaneous human approval by store policy.
- tool: cancel_checkout
  reason: UCP-only; this is the reversal path for a checkout that has not completed.
- tool: get_order
  reason: UCP-only; there is no anonymous REST order lookup.
- tool: search_shop_policies_and_faqs
  reason: >-
    Exposed only on the Shopify Storefront MCP endpoint (/api/mcp), not on the UCP endpoint. It is
    the single tool the two narrower storefronts expose at all.
- tool: get_product_details
  reason: >-
    Storefront-MCP-only naming of the product read; the UCP endpoint calls the equivalent get_product.
rest_only:
- path: GET /sitemap.xml
  reason: Crawlable index of the store; no MCP tool returns it.
- path: GET /agents.md
  reason: Agent instruction document; served over HTTP only.
- path: GET /policies/{policy}
  reason: >-
    Full policy text is served as HTML; the MCP surface only offers a search over policies and FAQs
    via search_shop_policies_and_faqs, and only on the Storefront MCP endpoint.
