API Bridge
by DuyAnh662
API Bridge exposes an internal HTTP REST interface that lets external programs control a running Minecraft Java client through requests.
What it does
Scripts and outside applications send HTTP requests to the mod, which then carries out actions in the game. The interface can move the player, turn the view by pitch and yaw, swing the hands, change the time of day, toggle the weather, place or break blocks anywhere, drop items, select hotbar slots and manage the inventory. Because the control runs over plain HTTP, the requests can come from curl, Python, JavaScript or any other language that can make them.
A macro system accepts a list of commands and runs them in sequence, which makes multi-step automation possible, for example a building routine or an automated mining bot. The mod is open source under the MIT License and is published for Fabric only, across 16 release versions, 1.21 – 26.2. Either side can run it, and neither needs it.
Key features
Player control
Requests move the player, change the look direction and swing the hands, covering most of what a player does with the mouse and keyboard.
World control
Scripts can set the time of day, toggle the weather, and place or break blocks at chosen positions.
Inventory handling
Items can be dropped, hotbar slots selected and inventory contents managed through the same interface.
Command macros
A list of commands can be sent in one request and executed sequentially, enabling longer automated routines.
Language agnostic access
Any tool that can send HTTP requests can control the game, with no client library needed for a given language.

How it compares
Peripheral is a Fabric mod for 1.21 – 26.1.2 that is client-side only and open source under the MIT License, so only the client needs it. APIBlock is also open source, under the GNU General Public License v3.0 only, and targets 1.21 – 1.21.11 with both client and server needing it. JsScripts is closed, under All rights reserved, and needs both sides for 1.21.8 – 26.1.1, so it fits servers where every player runs the mod.
