The only think you can configure server side is the block pass list. It is configured by a vanilla tag, so you just
have to set up a tag on the severer, then all the clients that use the mod will be configured, no need to install the
mod on the server. (Only thing to add is that the clients can override if they use the server tag or not)

If you wish to:

• make your own tag just
  go here for the example pack and then
  just reconfigure it as you like.
• use the default pack
• disable to mod empty pack

As stated in server config most configs are on the client:

• "blockBeams" is the list of blocks that will emit the particles and there color. It has a very simple format
  of ["namespace:block": hex color]
• "blockCheckType" is the way the mod check for what blocks to pass through
  • SERVER_ONLY - Gets the tag from the server and checks based on that, if the server has no tag then the mod is
    disabled [DEFAULT]
  • CLIENT_ONLY - Uses the client tag from his config (Use only if it is okay to do on the server)
• "clientTag" The client equivalent of the server side tag. Works like vanilla tag.
