Finance is entering its 'mod era' as AI agents reshape how customers interact with financial products

The author argues AI agents will become a primary channel for financial services, as mobile apps once did, letting customers' agents handle tasks like freezing cards, refunds, and expense filing. He already runs expenses and invoicing through agents with scoped access to a Gmail account. Citing S&P Global's data integration into Claude and protocols like x401 (NIST IAL2 identity proof) and MCP, he says banks should offer agents controlled access. Reg E liability for agent actions remains unresolved, and he suggests payment systems should enforce authorization limits, such as rejecting a $2,000 request under a $200 cap.
