Hmm, I've not done any testing or work with mcpc-plus before, so I'm starting from zero here.

A quick googleing on the name lead me to:
http://ci.md-5.net/job/MCPC-Plus/
From which I downloaded:
http://ci.md-5.net/job/MCPC-Plus/lastSuccessfulBuild/artifact/build/distributions/mcpc-plus-1.7.2-R0.4-forge1033-installer.jar

I ran that and had it install the server to a directory. From there I ran:
java -jar mcpc-plus-1.7.2-R0.4-forge1033-B47.jar

This did a bunch of setup. One thing it did is create a "plugins" folder. I copied ToolBelt.jar version 0.9 into that folder, and entered "reload" on the console. This spit out a bunch of text including the lines below:
Feb 22, 2014 11:52:09 PM org.bukkit.plugin.PluginLogger log INFO: [ToolBelt] Loading ToolBelt v0.9 Feb 22, 2014 11:52:09 PM org.bukkit.plugin.PluginLogger log INFO: [ToolBelt] Enabling ToolBelt v0.9 Feb 22, 2014 11:52:09 PM com.github.peter200lx.toolbelt.ToolBelt loadConf INFO: [ToolBelt][loadConf] config.yml copied from .jar (likely first run)

Based on the fact that I'm seeing that output, it seems like mcpc-plus is at least loading ToolBelt fine.

Could you please give more information such as where you got your version of mcpc-plus, and a link to the server jar that you are running? I currently do not have enough information to help you. My plugin is written for Bukkit, and I can't guarantee compatibility with other random server types, but I can try and reproduce your problem if you give me more information.

Looks like running the install did the trick. It loads fine now. Thanks for checking into this. I LOVE this mod.

Glad to hear it's working for ya!

Here is good tutorial with scripts that does all of this http://youtu.be/wMfGjSC6O4Q
