ServerChan
Imagine a Minecraft server where the chat feels alive, where an AI-powered helper reacts to player joins, cracks jokes about unexpected deaths, and even runs commands when you ask nicely. That is exactly what ServerChan delivers. This friendly, open-source add-on plugs into your server and gives it a personality, all while respecting your control over when and how it speaks.
What Makes ServerChan Special?
ServerChan is not just another chatbot mod. It is built from the ground up to be a server companion. It listens to chat, understands context, and decides intelligently whether to respond. The result is a lively atmosphere without the spammy interruptions that plague lesser bots. Whether you run a cozy SMP with friends or a bustling public network, ServerChan adapts to your community’s vibe.
Core Features
- AI Chat Integration – Connects to OpenAI-compatible APIs, including OpenAI, Azure, and local LLMs like Ollama, so you can choose the brain behind the bot.
- Smart Response System – An optional intention checker uses a smaller, faster model to evaluate whether the AI should reply, preventing out-of-place messages.
- Game Event Awareness – Reacts to player joins, leaves, deaths, and other in-game happenings, making the world feel responsive.
- Command Execution – With permission controls, the AI can run Minecraft commands via function calling, turning chat requests into actions.
- Fully Configurable – Tweak prompts, model parameters, response behavior, timezone, and more through a simple YAML file.
- Internationalization – Built-in support for English, Chinese, and Japanese, with locale settings for message formatting.
Compatibility and Loader Support
ServerChan for Minecraft works across a wide range of versions, from the older 1.12 all the way up to the latest 1.21. It supports multiple server loaders, so you can use it no matter how your server is set up. Fabric, Forge, NeoForge, and Spigot/Paper are all covered, though availability varies by game version. For instance, Fabric starts at 1.14, Forge is supported from 1.16 onward, and NeoForge is available for 1.20 and 1.21. Spigot/Paper users can enjoy ServerChan on every version from 1.12 to 1.21. This flexibility means you can bring AI-powered chat to almost any server environment.
How to Install ServerChan
Getting started with ServerChan is straightforward. First, download ServerChan from Modrinth or CurseForge, picking the jar that matches your server’s loader and Minecraft version. If you are using the foxygame.net launcher, you can skip the manual search entirely—the launcher’s built-in add-on catalog lets you install ServerChan with a single click, automatically selecting the correct file for your mod loader and version. For manual installation, place the jar into your server’s mods folder (or plugins folder for Spigot/Paper). Launch the server once to generate the configuration file, then add your OpenAI API key and adjust any settings to your liking. Restart or reload, and ServerChan will be ready to chat.
Configuration Essentials
After the first run, you will find the config file at config/serverchan.yaml for modded servers or plugins/ServerChan/config.yml for Paper/Spigot. The only required setting is your OpenAI API key, but you can also customize the base URL if you are using a compatible provider like a local LLM. The model, temperature, context size, and bot chat color are all adjustable. For example, you can set the model to gpt-4o for snappy replies or a local model for privacy.
Fine-Tuning the AI’s Behavior
The intention checker is a powerful tool to keep responses relevant. It uses a separate, faster model (defaulting to qwen3-235b-a22b-2507) to score whether the AI should jump in. You can tweak the responseProbabilityThreshold to make the bot more or less chatty. There is even a fast-path option that starts generating a response early if the intention score is high enough, cutting down on wait times. For servers that want a truly unique personality, custom system prompts are the key. The mod ships with example prompt files in the example/ folder, including the exact setup used on the OnlyMyRedstone community server. Copy and remix these to define how your AI thinks and speaks.
Commands and Permissions
All ServerChan commands require operator permissions (level 4). The main commands are:
/serverchan reload– Reload the configuration without restarting the server./serverchan reset– Clear the AI’s conversation memory./serverchan kill– Reset the OpenAI client connection./serverchan disable– Pause all AI responses./serverchan enable– Resume responses.
When the AI executes commands, it can inherit the permission level of the player who triggered it, so you never accidentally give a regular player admin powers. This makes command execution safe and controllable.
Under the Hood
ServerChan’s workflow is simple yet effective. A player sends a chat message. If the intention checker is enabled, it quickly evaluates whether a response is appropriate. If yes, the main model generates a reply, optionally calling Minecraft commands if needed. The response is then broadcast to all players. The AI maintains a conversation context of up to 20 messages, so it can reference earlier chat and stay coherent. Thanks to its efficient design, responses typically arrive in 2–5 seconds, and intention checking finishes in under a second when using fast inference providers.
Why ServerChan Stands Out
Many server bots feel robotic or spammy. ServerChan’s intention checker and customizable prompts let you craft an AI that fits your server’s culture. The multi-loader support means you are not locked into one ecosystem, and the open-source GPLv3 license invites community contributions. Whether you want a silent helper that only speaks when spoken to or a chatty companion that greets every player, ServerChan gives you the tools to make it happen.
For server admins who value convenience, the foxygame.net launcher integrates ServerChan directly into its add-on catalog, offering one-click installation and automatic updates so you never have to worry about version mismatches. This makes keeping your AI companion up to date effortless, even across major Minecraft updates.
ServerChan transforms a standard Minecraft server into a living, breathing world where the game itself seems to have a voice. Download ServerChan today and give your community a helper that is as smart as it is friendly.
