Ollama MC
by GetCmdRolled
Ollama MC lets players chat with a local Ollama language model inside the game, with the model answering in the same chat the friends use.
What it does
Players talk to a configured large language model through the Ollama API, so the AI joins a game with real friends. The default model is llama3.1:latest, and the user installs Ollama and the model on their own PC before the mod can respond. A web server runs by default, and the chat trigger and the name the model answers to are both set in the configuration. Responses depend on the power of the machine, so slower computers take a while before replies appear.
The mod runs only on the client, so a server does not need to install it, and each player who wants the AI installs it alongside Fabric API and Cloth Config API. Mod Menu is optional and only adds a settings entry. Other players see messages sent through the same name and can talk with the model too. The project is open source under the GNU General Public License v2.0 only, and the source code is public. Files target 1.21.1 – 1.21.11, with 1.2.0 for 1.21.11 as the latest Fabric file, last updated 2026-02-28.
