What update_account does on Max MCP Server

From the tool's definition Tool description states "Update account sender name, timezone, working hours, and email signature" — explicitly modifies account settings.

update_account Rate-limited

update_account stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
