No UCP successor for search_shop_policies_and_faqs before the Aug 31 sunset

Agentic Commerce

We run conversational agents on 8 Shopify storefronts and are migrating from the Storefront MCP (/api/mcp) to /api/ucp/mcp ahead of the August 31, 2026 sunset. Catalog and cart are covered: with our agent profile declaring dev.ucp.shopping.catalog.search, catalog.lookup and dev.shopify.catalog, tools/list returns the 12 tools we need.

The gap is search_shop_policies_and_faqs, which our agents rely on for shipping, returns and warranty questions. It is only exposed on /api/mcp, and that endpoint returns sunset: Mon, 31 Aug 2026 00:00:00 GMT on every response — including the tools/list that advertises the tool. We could not find an equivalent on /api/ucp/mcp: without a profile the server’s full set is 13 tools and none covers policies or FAQs.

Three questions:

1. Is there a UCP capability we should declare to get a policies/FAQ tool, similar to how catalog tools require dev.ucp.shopping.catalog.*?

2. Does the August 31 sunset apply to the whole /api/mcp endpoint, or only to the cart tools deprecated in favour of UCP Cart MCP? Your Storefront MCP server docs show no deprecation notice for this endpoint, which conflicts with the header.

  1. If there is no successor, what is the recommended path for policy and FAQ answers after the sunset?

Answering my own question after digging into the docs: only the cart tools were deprecated, not the endpoint. The changelog states that get_cart and update_cart on /api/mcp are deprecated in favour of the UCP Cart MCP, and search_shop_policies_and_faqs is not mentioned anywhere in it
