IronDuty Plugin

The IronDuty plugin is designed for server staff. It works with commands like /duty and /unduty. When a staff member uses /duty, their skin gets a glowing outline based on their rank color on the server, making them visible even through walls.

This plugin is specifically made for roleplay servers.
It also includes Discord webhook support: when you set up a Discord webhook, the plugin sends the duty and unduty timestamps of staff members to the Discord channel.
This allows you to monitor whether your staff are actually spending time in duty mode or not.
