LLMNotifications

Plugin to Create AI Customized Join & Quit Messages

LLMNotifications generates funny, customised join and quit messages for players using AI.

It can use:

• a local AI running on your server (Ollama), or
• cloud AI such as OpenAI or Anthropic.

Messages can include player and server information such as name, world, playtime and more.

Example prompt:

Write a funny 4-line rhyme to welcome @player to the server. Mention their world (@world).

You can also store extra information about players using the player memory feature, such as hobbies or favourite music, allowing the AI to personalise messages even more.

Configuration

When the plugin first runs it creates:

• configure fallback messages
• enable or disable player memory

Look through the file for comments explaining each option.

Example Prompts

First Join

• Welcome @player to the server with a short funny rhyme.

Join

• Write a sarcastic welcome back message for @player.

Quit

• Write a dramatic goodbye message for @player leaving @world.

Keeping messages short usually works best for chat.

Player Memory

You can store extra information about players that the AI can use when generating messages.

Examples:

• favourite music
• hobbies
• running jokes on the server

Example:

/llmnotifymemory add Steve loves cheese

The AI will automatically see this information when generating messages.

Supported Prompt Placeholders

You can use these in prompts and fallback messages:

• @player
• @display_name
• @uuid
• @world
• @x, @y, @z
• @health
• @food
• @level
• @gamemode
• @online_count
• @is_op
• @first_join
• @last_played
• @playtime_hours
• @player_memory

---

Tips for Better Prompts

• Keep output short so it fits in chat.
• Ask for a specific number of lines if needed.
• Describe the tone you want (funny, sarcastic, dramatic, etc).

Example:

Write a short medieval themed welcome message for @player in 3 lines.

Ollama Help

If you choose to use your own locally hosted ollama server (you will need to know how to set this up). There are some Ollama specific settings in the config file that is created when the plugin first loads:

  ollama:
    base-url: "http://127.0.0.1:11434"
    # there are some great small models designed for humour and sarcasm
    model: "MeaTLoTioN/LisaBot"
    # Optional: how long Ollama should keep the model loaded (examples: "5m", "30m", "1h", "0")
    keep-alive: "1h"
    # Optional: periodically ping Ollama with a tiny generation request to keep model warm
    keepalive-ping-enabled: true
    # Frequency for keepalive ping task when enabled
    keepalive-ping-interval-seconds: 300

The keep alives stop your Ollama model from unloading as the initial load time for some models may be slow enough that the plugin times out. You can also increase the request-timeout-seconds setting in the config file.
