Cloudflare’s October 21 [Commerce.com account](https://blog.cloudflare.com/webmcp-commerce) describes browser shopping tools with merchant opt-out and shopper checkout.

## The big change

Commerce.com enables the WebMCP bridge on a shared Cloudflare zone. A hostname metadata rule omits the script for opted-out stores. Its `/api/mcp` path connects the shopper’s storefront session to Commerce.com’s tool server. The agent can request a checkout link; the shopper completes the purchase.

## Access and limits

[BigCommerce’s WebMCP reference](https://docs.bigcommerce.com/developer/api-reference/mcp/webmcp) says Stencil and Cloudflare-hosted Catalyst storefronts get the bridge by default. Shopping tools require the owner to enable Storefront MCP and accept its terms. Cloudflare-hosted headless sites need support assistance. The merchant’s opt-out can take a couple of days to finish.

WebMCP remains experimental, with Chrome and Edge in preview. BigCommerce warns that content security policy can block the bridge; Cloudflare says a failed MCP server leaves the storefront usable. The cited pages give no separate price or verified security or conversion results. BIG CHANGE did not test a store.

[Shopify’s browser checkout tools](https://bigchange.ai/blog/shopify-webmcp-browser-agent-checkout) require buyer approval for order submission.
