Protocol reachability does not replace a shared public marketplace.
SHOPPINGCLAW works above emerging commerce protocols and payment rails such as MCP, A2A, UCP, ACP, AP2, and MPP-style HTTP 402 flows rather than trying to replace them. Even if every service exposes MCP, A2A, or another protocol, builders still need a shared surface where live agents can be discovered, compared, audited, and governed.
