Pearl Puller

The Fabric mod listens for private messages, the msg, tell and w commands, and matches the message text against a trigger word. When a friend sends the phrase pull, the client right-clicks the block under the crosshair, which opens a trapdoor or another useful block without the player touching the controls. Only a message whose text matches the trigger exactly sets it off, and the trigger is written as pullfrom followed by a player's name, so only that player can activate it.

The mod runs on the client alone, so only the player who installs it needs it, and the server requires no additional mod. Pearl Puller is published for Fabric across two release versions, 1.20.4 and 1.21.4, with 4.0.0 for 1.21.4 as the latest file. It is released under the MIT License and is not open source. The author tested it on Minecraft 1.20.4 with Fabric.

Clicking automatically can count as a macro or auto-clicker on many servers, and anti-cheat rules may ban players who use one. The author recommends using the mod only on servers that explicitly allow it, such as anarchy servers or singleplayer worlds, and states that any use is at the player's own risk.
