Awesome Mineflayer MCP server

awesome-mineflayer-mcp

A production-ready Model Context Protocol server that gives an LLM agent standalone-equivalent control over a Mineflayer Minecraft bot — movement, mining, crafting, inventory, combat, containers, chat, and much more — exposed as 123 strongly-typed tools across 26 groups, plus guided prompts, vision (real first-person screenshots + schematic maps), persistent waypoints, build/dig macros, and dual (poll + push) event streaming, with full bot lifecycle management. Tool results carry both human-readable text and machine-readable structuredContent.

Backed by the Mineflayer ecosystem: mineflayer-pathfinder (A\* navigation), mineflayer-pvp (combat), mineflayer-collectblock (gathering), mineflayer-tool (auto tool-select), mineflayer-auto-eat, and mineflayer-armor-manager.

Requirements

• Node.js ≥ 20 (developed on 22.16)
• A Minecraft server to connect to (Java Edition). The bot auto-detects the server version. Don't have one? See Get a server to test against.
• For online-mode servers: a Microsoft account (auth: "microsoft").

Supported versions

A few tools only work on newer versions/features (e.g. elytra_fly, chat signing). On a version mismatch the bot is kicked with an outdated client/server message — pass an explicit version.

Installation

Run it on demand with npx (no install needed):

npx awesome-mineflayer-mcp

…or install it globally:

npm install -g awesome-mineflayer-mcp
awesome-mineflayer-mcp

The server speaks MCP over stdio, so it is normally launched by your MCP client rather than run by hand.

Use with an MCP client

Add it to your client's MCP server configuration. The recommended form uses npx so you always get the latest published build:

Claude Desktop (claudedesktopconfig.json), Claude Code, Cursor, or any stdio MCP client:

{
  "mcpServers": {
    "mineflayer": {
      "command": "npx",
      "args": ["-y", "awesome-mineflayer-mcp"],
      "env": {
        "MCP_DISABLE_GROUPS": ""
      }
    }
  }
}

If you installed it globally, use "command": "awesome-mineflayer-mcp" with "args": [] instead.

Get a Minecraft server to test against

If you don't already have a server, spin up a throwaway offline-mode one with Docker (no account needed):

# from a clone of this repo:
docker compose up -d        # offline 1.20.4 server on localhost:25565
docker compose logs -f      # wait for "Done (…)! For help, type "help""

…or a one-liner without the repo:

docker run -d --name mc -p 25565:25565 -e EULA=TRUE -e ONLINE_MODE=FALSE -e VERSION=1.20.4 itzg/minecraft-server

Then connect: connect_bot { host: "localhost", username: "DevBot", auth: "offline" }. Tear it down with docker compose down -v (or docker rm -f mc). Don't expose an offline-mode server to the public internet.

Autonomous operation (default account)

For hands-off use, configure a default account so the bot connects automatically on startup — no connect_bot call required. Run the interactive setup:

npx awesome-mineflayer-mcp setup
