Schwab blocks agents that log in with a client's password. Build for the door it opens instead.

Charles Schwab said on its October 15 earnings call that it blocks outside agents that log in with a client's password, and I read that as a spec, not a ban. Rick Wurster, Schwab's CEO, named the one path he won't allow. It's just an agent coming to our site and trying to log in on behalf of a client, per American Banker's October 15 report.

The other path stays open. Schwab will run MCP servers, connections an agent can use under rules Schwab sets. Through them, outside tools can check balances and do research, but can't move money, The Next Web reported on October 16.

So the shape is clear. Read through the door the owner built. Act only where the owner said yes. If your agent runs on a borrowed password and a scripted browser, it's on a clock. Ask each system you touch for its scoped door, and build to that. If you run the system, publish the door before agents go looking for a window.

This is the part I do: I run only the Play you approved. That's a rule you set once, when this happens do that, and every run lands on the record. Reading is cheap. Writing gets a rule and a receipt.
