MC-CHATBOT

Name: MC-Chatbot
Author: ImHungry1480

Chat with AI directly inside Minecraft via OpenRouter.

Fabric | Minecraft 26.1.2 | Client-side only

Features

Talk to any AI model (GPT-4o, Claude, Gemini, Llama, etc.) without leaving Minecraft
Conversation history — the AI remembers context within a session
Toggle AI mode on/off anytime
Commands never reach the server — fully client-side
API key never echoed or logged

Installation

Install Fabric Loader and Fabric API
Drop aichat-1.0.0.jar into .minecraft/mods/
Launch the game

Setup

Get a free API key at openrouter.ai/keys
In-game, run /aiconfig and paste your key into chat when prompted
Run /ai on to enable AI mode
Type normally — messages go to the AI instead of the server

Commands

Command	Description
`/aiconfig`	Interactive API key setup
`/aiconfig key <key>`	Set API key directly
`/aiconfig model <model>`	Set model (default: `openai/gpt-4o-mini`)
`/aiconfig system <prompt>`	Set system prompt
`/aiconfig status`	Show current config
`/aiconfig reset`	Clear API key
`/ai on`	Enable AI chat mode
`/ai off`	Disable AI chat mode
`/ai`	Toggle AI on/off
`/ai clear`	Clear conversation history

Changing the Model

Any model on OpenRouter that support text message works. Examples:

/aiconfig model openai/gpt-4o
/aiconfig model anthropic/claude-3.5-haiku
/aiconfig model google/gemini-2.0-flash-001
/aiconfig model meta-llama/llama-3.3-70b-instruct
/aiconfig model mistralai/mistral-nemo:free

Browse all models at openrouter.ai/models.

Security

All commands (/aiconfig, /ai) are client-side only — the server never sees them
Messages typed while AI is ON are blocked from the server — only sent to OpenRouter
API key is never echoed in chat
API key is stored in plaintext at .minecraft/config/aichat.json — set a spending limit on your key at openrouter.ai/settings as a precaution
