Badge MCP

Badge provides persistent identity for AI agents across merchant sites, allowing agents to prove they are authorized actors rather than bots. It issues credentials carried on every request, which merchants verify to accumulate trust over time. The MCP server wraps the SDK to support identity declaration, visit tracking, and outcome reporting for agents using MCP clients.
