minecraft-mcp

🤖 minecraft-mcp lets an AI agent see and run your Minecraft server. Ask Claude “who’s online and where are they?”, “why is the server lagging?”, or “give everyone bread and set the time to morning”, and it answers with real data from your world.

It runs next to your AI client: Claude Desktop, Claude Code, Cursor, VS Code, or anything else that speaks MCP. From there it talks to WorldAPI on a Paper, Fabric, or NeoForge server, or in the world you play alone. The token you give it decides what the agent may do.

What you get

• 🧰 51 tools for the server, worlds, blocks, chests, entities, players, commands, leaderboards, recipes, configs, logs, and Java scripts. Most take several targets at once, so the agent makes fewer calls.
• 🎒 Inventories in depth: every item’s enchantments, durability, and potion effects, and what’s inside shulker boxes and bundles.
• 📜 Configs and logs: the agent reads the console and any config, and with the right token changes a value and keeps its comments.
• 🔑 Only what your token allows: a viewer token shows 19 tools that only look, and read-only mode hides every write.
• 🎮 Singleplayer, no setup: with the WorldAPI mod in your game, minecraft-mcp finds the open world by itself and follows you from world to world. Ask “what am I looking at?” while you play.
• 🙋 “Me” means you: set your player name, and “where am I?” just works.
• ⏳ Live events: “tell me when Steve joins”.
• 📣 Discord and Telegram in one sentence: “send deaths to my Discord” or “post joins to Telegram in Russian”, and the agent connects them through WorldAPI’s webhooks. Slack, Teams, and Google Chat too.
• ↩️ Undo: the agent reads a build before it changes it, and takes back what it placed if you don’t like it.
• 🧭 Never stuck on setup: when the address, the token, or WorldAPI itself is missing, the agent says what’s wrong and how to fix it, in game or in the admin panel.
• 🛡️ Safe by design: game text is fenced as data, tools say when they destroy something, and the token never leaks.
• 🔌 Every client: Claude Desktop in one click, or any MCP client over stdio or HTTP.

Get started

1. Install WorldAPI 4.2.0 or newer on your Paper, Fabric, or NeoForge server, and make a token with /worldapi token create agent. Playing alone? Put the WorldAPI mod in your game and skip the address and the token: claude mcp add minecraft -- npx -y @mairwunnx/minecraft-mcp. The Singleplayer page has the rest.
2. Add minecraft-mcp to your client. In Claude Desktop, open minecraft-mcp.mcpb. In Claude Code:

   claude mcp add minecraft -e WORLDAPI_URL=http://localhost:8110/api/v1 -e WORLDAPI_TOKEN=your-token -- npx -y @mairwunnx/minecraft-mcp

1. Ask “what’s the server status?”. The Installation page covers Cursor, VS Code, and HTTP.

Try it live

Moonlands, my hard survival server with friends, runs WorldAPI and lets anyone read it. Point the agent there without a token:

claude mcp add moonlands -e WORLDAPI_URL=https://minecraft.mairwunnx.com/worldapi/api/v1 -- npx -y @mairwunnx/minecraft-mcp

Then ask “who played the most on Moonlands this week?”.
