What is this mod?

This Fabric mod creates LLM-driven characters that can reply in chat and perform basic player actions. NPCs are configured through an in-game menu.

In short: Interesting for experimenters and server owners who value local models and direct control over characters.

What it can do

  • Create and configure individual NPCs
  • Local models through Ollama
  • Replies in public or directed chat
  • Optional text-to-speech

What you need

  • Minecraft 1.20.1
  • Fabric
  • Server and client installation for configuration
  • Ollama, Player2, or the OpenAI API

Installation

  1. Install the correct Fabric version for Minecraft 1.20.1.
  2. Choose a file for your exact game version on the official project page.
  3. Move the .jar file into .minecraft/mods.
  4. Add every dependency listed by the author, then launch a separate test profile.
  5. Configure a local model or your own API key. Never share the key.

Important limitations

  • Task execution is still being improved
  • Operator permission is required for configuration
  • Setup is more involved than a typical client-side mod
