You script a nightly Claude Code run that needs a remote MCP server behind a browser sign-in. Nobody will be watching. What has to be true for the run to reach that server?

Nothing in particular, because the run will pause at that point and wait for somebody to authorise it.
The credential has to exist before the run starts, because a non-interactive session cannot sign in.Correct answer
A flag has to be passed to the command, which authorises the sign-in without a person being present.
Nothing in particular, because the run opens a browser on the machine and completes the sign-in itself.

Show answer & explanation

Correct answer: B. The credential has to exist before the run starts, because a non-interactive session cannot sign in.

Explanation

The principle — Sign-in is an act by a person. Automation can use a credential that already exists; it cannot create one.

Why the key is correct — In non-interactive mode there is no MCP panel, so Claude Code cannot run the sign-in flow for you. The credential has to be established from an interactive session beforehand, and the scheduled run then reuses what is already stored. Planning that step is the difference between a job that works and one that silently loses a server.

Why the others are wrong — No browser is opened on your behalf in a scripted run, and a build machine often has none. No flag substitutes for a person authorising at the identity provider. And the run does not pause waiting for someone, because it has no way to ask.

Remember this — Authenticate the machine before you schedule the job, not during it.
