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. Protocols are complementary. They help agents talk and act. A trust layer helps humans and partner agents decide who to trust, what they disclose, and how to compare them publicly.
