Deploy MCBot

MCBot is a Minecraft AI chat bot that monitors server logs and responds to players via RCON. It supports multiple AI providers and can execute in-game commands (give items, teleport, change weather, etc.).

Prerequisites

Before deploying, ensure:

1. A Minecraft Java Edition server is running
2. Python 3.10+ is installed
3. mcrcon CLI is installed (see install guide)

Step-by-step deployment

1. Clone and install

git clone https://github.com/longsizhuo/mc-chat-bot.git
cd mc-chat-bot
pip install -r requirements.txt

2. Enable RCON on the Minecraft server

Edit server.properties in the Minecraft server directory:

enable-rcon=true
rcon.port=25575
rcon.password=<generate-a-secure-password>

Then restart the Minecraft server.

3. Create config.yml

cp config.example.yml config.yml

Edit config.yml with the correct values:

• server_dir: absolute path to the Minecraft server directory
• ai.provider: one of deepseek, openai, anthropic, ollama, custom
• ai.api_key: the API key for the chosen provider (not needed for ollama)
• rcon.password: must match server.properties
• bot.name: the display name in chat
• bot.language: zh for Chinese, en for English

See references/CONFIG.md for all configuration options.

4. Test

python run.py -c config.yml

Verify the bot starts without errors. Join the Minecraft server and type something in chat — the bot should respond.

5. Run as a systemd service (optional)

sudo tee /etc/systemd/system/mcbot.service > /dev/null << EOF

sudo systemctl daemon-reload
sudo systemctl enable --now mcbot.service

Troubleshooting

• "mcrcon not found": Install mcrcon, see references/INSTALL_MCRCON.md
• "RCON error: Connection refused": Check that RCON is enabled in server.properties and the server is restarted
• "AI API error": Verify api_key and base_url in config.yml. For Ollama, ensure Ollama is running locally
• Bot not responding: Check that server_dir and log_file in config.yml point to the correct log file
• Bot responds but commands don't work: The player name in game must match exactly (case-sensitive)
