It's optional. I use it because it does no harm and some good.

In addition to using commas to separate clauses, native English speakers often also use them to indicate pauses one would normally use when speaking the sentence aloud. It is non-grammatical, but commonly used. The comma in your sentence is not necessary, but it's fine to include it.
