URLium is a Polymer Library server-side mod that transmits redstone, entity, command, and blockstate data over HTTP(S) to a configurable URL.

URLium only transmits outbound requests and logs the HTTP response data to the server log. URLium does not allow incoming commands or controls. Any in-bound control of the server is performed by existing native RCON connections, not any feature of URLium.

URLium Block
reports redstone power level changes
can also be right-clicked by user
transmits ‘place’, ‘break’, ‘use’, and ‘sense’ events
URL Post Wand
use as tool to report target block or entity data
URL Config Wand
use on Signs, Chests, Barrels, Comparators, Light Sensors, Sculk Sensors, Hoppers, Droppers, Dispensers, Lecterns, and Mobs will enable/disable change reporting
chest contents sent when changed or block update occurs (not always real-time)
sign front and back text content sent when changed
comparator power level sent when changed
sculk sensor power, phase, and frequency sent when changed
light sensor power level sent when changed
when a writable book or written book is placed on lectern, contents will be sent
mobs and entities with change reporting send an “interact” event when right-clicked by any user

Ugetblock Command
Usetblock Command
RCON-accessible command to query and set block data for remote webserver RCON response
allows external server to perform lightweight query and get raw (‘F3+i’ debug query) block data
forces block loading / generation if unloaded
specify dimension (unlike regualr /setblock)
silent execution
webserver application/game logic can be written in ANY web language that can respond via RCON
PHP, Python, Java, JS, Go, C#… anything!
“/webcom” Commands
Users may send message to webserver with “/webcom …message text…”
Set command name (“webcom”) in config file to any unused command name
Up to 3 custom commands!

Respond to the Minecraft server via RCON to complete the circuit of input/output.
