brick chimney repair/replace

brick chimney for an oil furnace. has a liner, looks like stacked clay blocks.
problem is a brick fell off. when I checked, the rest of the top row was just sitting there. no mortar left holding them in place. I could probably take the chimney down to the roofline with very little effort.
the chimney is 35" above the roof. I can stand next to it to do repairs.
my question is, should I just add mortar to all the seams, repointing I think they call it, or is it in such bad condition it would be better to take it down to the roofline and rebuild it?
are there any other options, like a very tall animal proof cap? I could take the bricks down to just below the roof, leave liner alone, attach the animal cap.
now I have a 35" tall animal cap where the brick chimney was. just wondering if that might be easier.

If it's that bad I would have the chimney inspected. The brick on the outside is mostly cosmetic but the condition of the liner should be verified.
