About this Mod

This is a fabric mod port of CyvClient 1.8.9's parkour features, and an alternative to MPKMod2. A forge mod version also exists for version 1.8.9 and version 1.12.2 (not maintained).

CyvFabric is a client-sided mod to enhance technical/theorycraft parkour. It does not modify game mechanics in any way, and can be used on servers. This mod provides on-screen labels for coordinates and various angles of the player at high decimal precision, as well as a personal best offset tracking system for repeated attempts on the same jump.

This mod also includes tick-based keystrokes for better clip analysis and sharing, as well as togglesprint and directionHUD as quality of life features.

Most mod features can be accessed from the base command /mpk.

Frequently Asked Questions

Cyv server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.

Is Cyv compatible with fabric and forge?

Cyv officially supports fabric, forge for Minecraft 26.1.2, 26.1.1, 26.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Cyv – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Cyv consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
