Major US banks are restricting third-party AI agents that log into customer accounts with customers’ own usernames and passwords. It is the same credential-based access that a federal open banking rule, now stalled in court, was designed to move the industry away from.Axios reported on October 22 that banks were detecting outside AI agents inside customer accounts, including some that attempted actions that appeared independent of their users’ instructions, citing people familiar with the matter. Reuters, citing two people familiar with the situation, reported the same day that major US banks have been blocking third-party agents from operating inside accounts and making transactions. Axios did not say how many accounts were involved or what the agents attempted.Morgan Stanley, which has blocked third-party agents, had not seen any unauthorised or rogue instances, a person familiar with the bank told Reuters. Charles Schwab chief executive Rick Wurster told Bloomberg Television on October 16 that the brokerage blocks large outside agents, including Meta’s Muse, “in the tens and twenties” each week. Schwab plans to let outside AI models check balances and research through its own MCP servers, but not move money, he said.https://www.artificialintelligence-news.com/news/banks-block-ai-agents-open-banking-rule/
