I have been searching up and down for the plugin MQ2ChatFilter that works with Underfoot. I play on EZ server and am willing to pay plat(that you can sell ingame for RL $$ as well), or if you would like to PM me and share this plugin. Thank you.

Do not think this site has a copy of this plugin. It can be gotten from VIP section of macroquest2.com VIP forums but you need to change some offsets and mkplugin.
It can also be gotten from several of the pay sites but I am very much against those other sites, selling access to plugins they are not the original authors of.
