boxloom
by k-yokoishi
boxloom lets Python programs control a Minecraft server through a local HTTP API, once it is installed on a Fabric server.
What it does
Installed on a Fabric server, boxloom exposes a local HTTP API that external Python programs can call. Through it a script can broadcast a system message to connected players, list who is connected, read each player's position and look direction, and set a single block in a loaded dimension. The API runs on the machine hosting the server, so requests stay local.
Only the server needs the mod, so players join without installing anything. It can run on a standalone server or inside a singleplayer world opened to the network. The JAR ships with its own server core, while Fabric API and Fabric Language Kotlin must be added separately. Files exist for Minecraft Java Edition 26.2, with Java 25 or newer and Fabric Loader 0.19.3 or newer. The license is MIT, and the code is open source.
Key features
Server broadcasts
A script can send a system message to every player currently connected to the server.
Player listing
The API returns the players connected at the moment of the request.
Player position and look
For each connected player, a script can read the current position and look direction.
Single block placement
A script can set one block at a chosen position in a loaded dimension.

Use cases
Scripted server events
A Python program can watch player positions and send broadcasts when a condition is met, such as a player reaching a marked area.
Remote building helpers
Scripts can place individual blocks in loaded chunks while a player watches the result in the world.
Who it’s for: Server owners and developers who already write Python and want to read player state or make changes from outside the game. Players need nothing installed to take part.
How it compares
boxloom is a Fabric mod that runs server-side only, so the server alone needs it, and it is open source under the MIT License. Trusted Links is a Fabric client mod for 26.1.2 that is also open source under the MIT License, but it changes nothing on the server side. MC Local API is a client-side Fabric mod for 1.21.8 – 26.2 under All rights reserved, so it is not open source and does not touch the server.
