CraftLLC YouTube Command Mod [CYCM]

Viewers in a YouTube live chat can trigger in-game commands. CraftLLC YouTube Command Mod, shortened CYCM, reads that chat through either direct API polling or a browser bridge, so the streamer can pick whichever setup works better for them. Viewers can queue whole sequences by separating several commands with a delimiter, and a sleep instruction inserts a wait before the next command runs.

The mod includes a fair budget system: a global limit, for example 20 repeats, is split between commands in proportion to the requests sent, so one viewer cannot take over the whole budget. Duplicate chat messages are grouped with counts such as x2 or x3 instead of flooding the screen, and an overlay shows what is running as it happens. A web-based dashboard, opened in a browser through the cycm http ui command on port 21456 by default, lets the streamer change keys, tokens, limits and blocklists without touching the game. The panel supports English, Ukrainian and Russian, and changes apply instantly. Command blocklists stop anything disruptive from getting through.

The mod is released under the MIT License and runs on Fabric 1.21.1 – 26.3 with Fabric API required. It is client-side only, so servers do not need it. The mod is not a relay for a full command engine; it sends the commands it receives as chat or as the game's own input. OAuth2 tokens refresh automatically.
