Do you have a full list of the NAICS, MCC, and SIC codes that can be returned?

The code systems are public and we return standard codes from them: NAICS from the US Census Bureau, SIC from the SEC, and MCC from Mastercard’s merchant reference booklet.

Baselayer returns the full six-digit NAICS code; the MCC and SIC codes on a prediction are the ones mapped to that NAICS code.
