ServerChan
by himekifee
ServerChan lets a server run an AI chatbot that answers players in chat and reacts to in-game events such as joins, leaves and deaths.
What it does
The chatbot is configured to talk through OpenAI-compatible APIs, including OpenAI, Azure and local language models, so the server owner chooses the backend. A secondary, quicker model can be turned on to judge first whether a chat line calls for an answer, so a crowded public server does not get a reply to every message. Conversation context covers earlier messages up to a configured context size.
Operators can shape the bot with custom system prompts, model settings and response behavior, so its personality suits the tone of the server. The AI can also run Minecraft commands through function calling, but only within permission controls, and those commands require operator permission level 4. Built-in interface text is available in English, Chinese and Japanese.
The mod runs on servers only and is published for Fabric, Forge, NeoForge and Spigot/Paper. Files cover 1.12 – 1.21.10 across 48 release versions, and the Fabric, Forge and NeoForge builds listed as latest target 1.21.10. The code is released under the GNU General Public License v3.0 only and is open source, with the source code and issue tracker publicly linked.
Key features
Smart response system
An optional intention checker decides whether the AI should answer a message, which limits replies to chat that needs one.
Game event awareness
Beyond chat, the bot also responds when someone connects, disconnects, dies, or when another server event takes place.
Command execution
The AI can carry out Minecraft commands through function calling, with permissions that the server owner controls.
Customizable personality
System prompts, model choice and response behavior can all be changed to match the character of each server.

Use cases
Cozy survival servers
A small server can use the chatbot to keep conversation going and welcome newcomers as they join.
Busy public servers
The intention checker and permission controls let a crowded server keep the bot from answering every message.
Who it’s for: Server owners who want a chat assistant that listens to conversation and reacts to game events. Players only need the server; the mod does not have to be installed on their side.
