Question: can you use mcedit on a server?
Answer: Yes) You can use a mod such as http://www.minecraftforum.net/topic...ilters-scripts-a-new-map-making-tool-updated/ (in game MCEdit) and it will be able to use filters/import schematics ect without "many" bugs. for example MCEdit doesn't like microparts much so it may not import those.
