Schwab Blocks AI Agents Like Meta's Muse, CEO Rick Wurster Says

Schwab's move comes as U.S. lawmakers have yet to define clear liability standards for autonomous AI actions, leaving firms to set their own boundaries. Wurster told Bloomberg Television that weekly security logs show unauthorized agent attempts intercepted in the "tens and twenties," which helps explain why the brokerage is drawing a line at transactional access rather than blocking AI outright.

The restriction is selective. Schwab is deploying controlled Model Context Protocol (MCP) servers, a standard that acts as a secure bridge for vetted third-party models to pull balance inquiries and market research without transactional clearance. For hands-on account management, customers are steered toward Charley, the firm's proprietary in-house assistant launched late last month.

The stance is not isolated. JPMorgan Chase CEO Jamie Dimon warned on an earnings call of potential "rogue agents" and said the bank will not permit external autonomous software to initiate wire transfers or settle bills. Even the restricted bridges carry risk: Google and JPMorgan recently patched vulnerabilities found within MCP-style connection architectures, suggesting the guardrails themselves need watching.
