With the limited facts you have provided, I can only assume that the police took you in protective custody because you were intoxicated and a possible danger to yourself. The police in Massachusetts can hold someone who is intoxicated in protective custody until they are sober or up to 4 hours. They may have taken your license because they did not want you to drive. They mailed it back because the police had no right to hold your license. Had you been arrested for drunk driving then the police could have taken your license if you refused the breath test or failed it.
