PePr - Permission Preflight

When a player tries an action that the mod predicts will be denied, a short chat warning appears, with rate limiting to prevent repeated messages. A compact HUD overlay can show the result of each check, placed above the hotbar or near the crosshair. The overlay is informational only and does not grant any permissions or bypass protection systems.

The mod is built for multiplayer dedicated servers, protected areas, spawn regions and adventure-mode zones, where the cause of a failed action is often unclear. It checks common vanilla restrictions for breaking, placing and using blocks, and it watches cancelled Forge interaction events, remembering recent denials so a restriction can be traced after a failure, even when no claim mod is named directly. Claim-related denials are still shown after a cancelled interaction through a recent observation provider. The mod reports only what the available checks determine, so a result of Unknown means it lacks enough information to say Allowed or Denied.

PePr - Permission Preflight is published for Forge only, with a single file for 1.20.1 (1.0.0, 2026-07-06). The server and every player need the mod installed. It is released under All rights reserved and is not open source.
