Spellwords
by cloverskid
Spellwords lets server owners attach commands to chat messages, so a phrase typed by a player can run a command on the server.
What it does
Each trigger entry pairs one or more words or phrases with a command. When a player sends a chat message that matches, the server runs the command. An entry can list several trigger words, and each entry carries its own cooldown, so a frequent phrase cannot fire the command again until the timer ends. Triggers work with text in non-Latin scripts as well.
Triggers can be limited by permission. With LuckPerms installed, access to a given trigger can be granted to some groups and withheld from others, and a cooldown permission sets a fallback timer for players who lack a specific one. An option cancels the original chat message, so the phrase is not shown to other players once the command has run.
Spellwords runs on the server alone and is open source under the MIT License. It is published for Fabric only, in a single build for 1.21.11, and LuckPerms is optional. The author wrote it first for a personal server and shared it publicly, and updates follow the needs of that server; older versions are backported now and then, and ports to other versions are welcome.
Key features
Word and phrase triggers
Entries match single words or full phrases in chat and run a configured command when a player sends them.
Multiple triggers per entry
One entry can respond to several trigger words, so variants of the same phrase share one command.
Per-trigger cooldowns
Each trigger has its own cooldown, which limits how often its command can run.
Permission-based access
Triggers can be restricted by permission nodes, with LuckPerms supported for managing who may use them.
Optional message cancelling
The original chat message can be cancelled so that the typed phrase is not broadcast to other players.

How it compares
ChatFilterV1 is a client-side Fabric mod released under the MIT License, built for 1.21 – 1.21.8 and not open source, so it filters messages on each player's own game. MuteIt is client-side, licensed under the Apache License 2.0 and covers 1.21.6 – 1.21.8. Spellwords acts on the server, so players need nothing installed.
