Cosy Integration Mod
by jabbekeipert
Cosy Integration Mod connects the Cosy game server tool to the metrics a Minecraft server reports about itself, including tick times and world state.
What it does
On Fabric, this server-side add-on gathers core server measurements at set intervals and sends them across the network to the Cosy API. It reads the overworld time of day, the raw world time, the current weather (clear, raining or thundering), the average milliseconds per tick (MSPT), a TPS value derived from MSPT and capped at 20, and the current system time in milliseconds since the epoch. Only the overworld is read for time and weather.
Because the metrics come from the instance the Minecraft server runs on, a server owner who uses Cosy can see these values next to deployment data. The Cosy Integration Mod exposes its custom metrics to Cosy, an open source tool for deploying game servers. Fabric API is required, and the mod is published for 26.3 at the latest file, 1.0+mc26.3, with builds covering 1.18 – 26.3 across 32 release versions. Files run only on the server, so players join without installing anything.
The mod is open source under the MIT License and was first published on 2026-02-20. Its last update was on 2026-09-29, and public source code, an issue tracker and a wiki are linked from its listing.

Use cases
Who it’s for: Server owners who deploy with Cosy and want server performance and world state in their custom metrics. Players and single-player users have no use for this mod.
How it compares
TPSnitch is a server-side only Fabric mod under the Apache License 2.0, open source, with files for 1.21 – 26.2. MiniHUD MSPT Provider is also server-side only and open source, released under CC0 1.0 Universal, with files for 26.1 – 26.1.2. Tab TPS is server-side only but not open source, under All rights reserved, and covers 1.20.1 – 26.2. Cosy Integration Mod targets a different consumer: it sends its readings to the Cosy API instead of showing them to players.
