What's Wrong?

It isn't possible to authenticate Claude Code using a pro subscription on a server os with no windows manager/browser via an ssh session.

Launching Claude Code for the first time or using claude setup-token produces a URL, I take the URL and paste into my host browser I get an Invalid Oauth Token message

What Should Happen?

Claude should allow the use of a secondary browser for authentication on a non desktop OS or provide a alternate method to complete Oauth

Use 'c' to copy and don't use the terminal commands such as shift-ctrl-c
