If a someone wrote an answer to a question asked by someone else, and you found the answer given matches your opinion on the points discussed. However, there are little things you do not find right to you.
You don't want to say I disagree with the writer on these points or I almost agree with the author. What you want is to focus on the answer objectively and do not mention the writer.
I know you can say I agree with someone, but I wonder if I agree with/to this answer.

"Agree with" is usually in direct reference to "having the same opinion as someone else".
"Agree with" is followed by a noun.
"Agree to" is normally in reference to "accepting something proposed by another party"
"Agree to" can be followed by a verb or a noun.
So in direct answer to your question, "agree with" is the correct option.
