Xaero's Map Server Utils Mod (1.21.11) – Fair-Play Mode Controls

Running a competitive Minecraft server where players use Xaero's Minimap or World Map? Xaero's Map Server Utils Mod gives server administrators direct control over which map features players can access — disabling cave mode, entity radar, or even the entire minimap with a single command. Downloaded over 279,000 times since its 2024 release, this lightweight server-side utility has become a go-to solution for tournament organizers and PvP server owners who need enforceable fair-play rules that players cannot bypass through client-side settings.

Key Features

• Fair-Play Mode: Run /function xaero:fairxaero to instantly disable cave mode and entity radar across your server, preventing unfair advantages in PvP and competitive scenarios.
• Full Minimap Disable: Use /function xaero:nominimap to completely turn off the minimap for all players — useful for hardcore survival or exploration-focused servers.
• Nether Exception: The /function xaero:xaerowmnetherisfair command allows cave mode specifically in the Nether while keeping fair-play restrictions active everywhere else.
• Silent Commands: Add silent/ before any command (e.g., /function xaero:silent/fairxaero) to apply restrictions without broadcasting system messages to players.
• Reset Controls: Use /function xaero:resetxaero to clear all system message flags and start fresh.
• Server-Side Enforcement: Restrictions are enforced at the server level, so players cannot bypass them by changing client-side settings.
• Auto-Execute on Join: The latest update adds automatic function execution when players join the server, ensuring rules apply without manual intervention.

FAQ

Does Xaero's Map Server Utils work with Fabric and Forge at the same time?

The mod supports Forge, NeoForge, Fabric, and Quilt, but you need to download the version that matches your server's mod loader. You cannot mix loaders on a single server installation.

Can players bypass the fair-play restrictions by changing their client settings?

No. Xaero's Map Server Utils enforces restrictions at the server level, so players cannot override them through client-side configuration changes.

How do I hide the system messages when activating fair-play mode?

Add silent/ before the command name — for example, use /function xaero:silent/fairxaero instead of /function xaero:fairxaero. This applies the restrictions without showing any messages to players.
