Nexvor - AI Chatbot for Minecraft

Transform your server with intelligent AI conversations!

Nexvor brings powerful AI capabilities to your Minecraft server, allowing players to have natural conversations with an AI bot. Perfect for roleplay servers, help desks, or just adding something unique to your community.

✨ Features

💬 Smart Conversations

Natural language AI powered by multiple providers (Groq, OpenAI, Anthropic, Ollama)
Persistent memory - The bot remembers past conversations with each player
Context-aware responses - Uses token-based context windowing for relevant answers
Configure the bot's personality with custom system prompts
Multi-provider support - Configure primary + fallback providers with automatic switching
Custom provider support - Connect to any OpenAI-compatible API (Perplexity, Mistral, etc.)
Casual chat trigger - Just mention the bot's name in regular chat!

🎮 Group Conversations (Medium Tier)

Private Groups - Create invite-only conversation groups with /nexvor group commands
Global Chat - Server-wide shared AI conversation where everyone participates
Proximity Chat - Location-based automatic grouping (150 block radius)
Players can be in multiple conversation contexts

🎯 Event Awareness (Medium Tier)

The AI reacts to 15 in-game events:

Player events: Deaths, advancements, level milestones, first join, join/quit
Combat events: PvP kills, boss kills (Ender Dragon/Wither), entity kills
Special events: Rare fishing catches, raid triggers/completions, boss spawns
Block events: Rare ore mining (diamond, ancient debris, emerald)

Configurable per-player with /nexvor events commands!
