Most often, the word 'setter' in a cryptic clue is a self-reference by the crossword setter, one that you would replace with the first person pronoun (I, ME, etc) to get the answer. A typical example:
THC 9473 (Gridman): Setter right about one's worth (5) MERIT
ME (setter) RT (right), around I (one)
