The smallest server implementation I've made was around 35kB on 64-bit Linux, compiled from C. There were no runtime configurable parameters and many of the features in a normal mqtt server were missing such as the $SYS topic hierarchy, bridging and persistence.
My current implementation is 130kB compiled on 64-bit Linux.
