With 1.9 came a shiny new tool to allow native status querying in vanilla Minecraft servers. This is a simple class designed to aid in retrieving any data from the servers.

from minecraft_query import MinecraftQuery query = MinecraftQuery("localhost", 25565) basic_status = query.get_status() print "The server has %d players" % (basic_status['numplayers']) full_info = query.get_rules() print "The server is on the map '%s'" % (full_info['map'])
Fully open. Go wild.
