Sound Webhook Alert is a client-side Fabric utility for Minecraft Java Edition 1.21.11.

It lets you listen for Minecraft sounds on your own client and send a Discord webhook message when a matching sound is heard. The server does not need to install the mod.

Open the in-game menu with V, paste your Discord webhook URL, choose a sound filter, enable the listener, and save.

Discord Webhook URL

The Discord webhook URL where alerts are sent.

The webhook URL is saved locally in:

.minecraft/config/sound_webhook_alert.json

Keep this URL private.

Sound Filter

The sound filter decides which Minecraft sounds trigger an alert.

Examples:

step
break
chest
minecraft:block.chest.open
minecraft:block.stone.break
minecraft:entity.zombie.hurt

Match Mode

Contains triggers when the sound ID contains your filter.

Example:

step

can match:

minecraft:block.stone.step minecraft:block.grass.step

Exact match triggers only when the full sound ID is exactly the same as your filter.

Cooldown

Cooldown controls the minimum time between Discord messages.

Recommended values:

10 seconds for testing
30-60 seconds for normal use

Include Position

When enabled, alerts include your current block position.
