Summary
The release adds a WebMCP layer to Spire storefronts for reading session and cart context, searching products with account-specific pricing, and adding, updating, or removing cart lines. It also improves server-side rendering resource use and adds storefront error timestamps and reference IDs for faster troubleshooting.
Why it matters
Commerce developers can expose controlled, structured actions to browser agents while preserving existing pricing, promotion, and entitlement logic.
