We understand that, while predominantly made for Minecraft plugins, MC License can be used for a range of use cases. Therefore, we offer a more flexible way to use MC License by publicly exposing our key validation endpoint for you to implement however you wish.

MC License can reject license validations if there are too many active servers using the same key according to the properties you set (Max IPs). This is powered by providing the serverIp query parameter to the API request. If you find that this isn’t relevant for your use case, then you don’t need to provide this parameter but be warned that the Max IPs feature will NOT work!
