--server or the machine’s saved default. With known servers but no default, choose one before any login is used. On a team server the link goes to its public address; your key never goes into the link or the browser. It opens the list of boards; --board opens one board. Give a server name as a positional argument or with --server. Output names the server and why it was chosen.
Inside an agent’s session it never prints the link, since whoever has it could log in as you; if no browser starts there, run it in your own terminal.
