Is it a good idea to go to a psychologist with a narcissist?

What is the purpose of the visit, is it to work on the relationship?

Because relationships are co-constructed this would also require change in the narcissist. I wonder if this is possible. In my experience many do not wish to change.

They will manipulate, either by charming the psychologist on to their side, or by diminishing the psychologist and you, therefore successfully disrupting the process.

Their objective is to gain control of the session. It is essential that the therapist is experienced and can see their game from the outset.

This situation unfortunately is often unworkable. How can we work with someone who wants to blame and doesn't want to change.

Give it a session or two, if u find these dynamics are at play stop attending the sessions and just work on yourself with a competent therapist.
