Enables AI agents to request policy-governed payments through MCP tools, with server-side enforcement of spending limits, merchant allow-lists, Pix BR Code validation, approval thresholds, and hash-chained audit logging in a sandbox. It lets agents check wallets, create card or Pix payment intents, and poll or list payments while keeping approval and limit changes out of agent control.
