Minecraft Bot Control MCP server

MCPMC (Minecraft Model Context Protocol) is a server that enables AI agents to control Minecraft bots using a standardized JSON-RPC interface. Built on top of Mineflayer, it supports navigation, block manipulation, inventory management, and real-time game state monitoring, all through a type-safe API with TypeScript support.

Installation

You can install MCPMC using your preferred package manager:

# Using npm
npm install @gerred/mcpmc

# Using yarn
yarn add @gerred/mcpmc

# Using bun
bun add @gerred/mcpmc

Basic Usage

Starting the MCP server is straightforward with the command line tool:

# Start the MCP server
mcpmc

The server operates via stdin/stdout using the Model Context Protocol, allowing AI agents to send commands and receive responses in a standardized format.

Using the MCP Inspector

For exploring the available API commands and understanding the protocol structure, you can use the built-in inspector:

bun run inspector

This tool provides detailed documentation on all available commands and how to properly format requests to the server.

Features

Minecraft Bot Control

MCPMC provides comprehensive control over Minecraft bots with capabilities including:

• Navigation: Move the bot through the Minecraft world
• Block manipulation: Break and place blocks in the environment
• Inventory management: Craft, store, and use items
• Entity interaction: Interact with mobs, players, and other entities
• Environment monitoring: Get real-time updates about the game state

Integration with AI Systems

The standardized JSON-RPC interface makes it easy to connect AI systems to control Minecraft bots. The protocol handles all the complexity of translating high-level commands into specific Minecraft actions.

Advanced Configuration

When starting the server, you can customize its behavior with environment variables or command-line arguments. Refer to the MCP inspector for detailed configuration options and their effects on the server's operation.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "mcpmc" '{"command":"npx","args":["-y","@gerred/mcpmc"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "mcpmc": {
            "command": "npx",
            "args": [
                "-y",
                "@gerred/mcpmc"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "mcpmc": {
            "command": "npx",
            "args": [
                "-y",
                "@gerred/mcpmc"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
