Metro Manager is a server utility mod for Minecraft 1.21.1 that lets server operators control when specific players are allowed to join.
With this mod, operators can place players on a managed access list and assign them to a specific time window. Players on that list will only be able to access the server during their allowed hours, making it easy to enforce scheduled playtimes, event sessions, staff testing periods, or limited-access community servers.
This is especially useful for:
- parental or family-managed servers
- private event servers
- community servers with scheduled access
- testing environments with restricted login hours
