インストール

クライアントを選択

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "minecraft-mcp-server-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/yuniko-software/minecraft-mcp-server"
      ]
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config を開く。保存後、アプリを再起動。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "minecraft-mcp-server-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/yuniko-software/minecraft-mcp-server"
      ]
    }
  }
}

Cursor は Claude Desktop と同じ mcpServers スキーマを使用。プロジェクト設定はグローバルより優先。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "minecraft-mcp-server-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/yuniko-software/minecraft-mcp-server"
      ]
    }
  }
}

Cline サイドバーの MCP Servers アイコンをクリックし、"Edit Configuration" を選択。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "minecraft-mcp-server-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/yuniko-software/minecraft-mcp-server"
      ]
    }
  }
}

Claude Desktop と同じ形式。Windsurf を再起動して反映。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "minecraft-mcp-server-2",
      "command": "TODO",
      "args": [
        "See README: https://github.com/yuniko-software/minecraft-mcp-server"
      ]
    }
  ]
}

Continue はマップではなくサーバーオブジェクトの配列を使用。

~/.config/zed/settings.json

{
  "context_servers": {
    "minecraft-mcp-server-2": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/yuniko-software/minecraft-mcp-server"
        ]
      }
    }
  }
}

context_servers に追加。保存時に Zed がホットリロード。

claude mcp add minecraft-mcp-server-2 -- TODO 'See README: https://github.com/yuniko-software/minecraft-mcp-server'

ワンライナー。claude mcp list で確認、claude mcp remove で削除。

ユースケース

実用的な使い方： minecraft-mcp-server

Minecraft Java Edition 1.21.11 — Create a singleplayer world and Open to LAN
minecraft-mcp-server configured — Add to Claude Desktop config with host, port, and username

フロー

Describe the build

Build a 10x10 stone house with oak wood corners, glass windows on each wall, an oak door, and a flat stone roof. Start at my current position.✓ コピーしました

→ Bot begins placing blocks systematically, reporting progress
Modify the build

Add a second floor with the same layout and a staircase connecting them.✓ コピーしました

→ Second floor built with stairs

結果： A complete structure built in Minecraft via natural language instructions.

注意点

Bot doesn't have required blocks in inventory — Ensure the bot has materials or switch to Creative mode for unlimited blocks

Send an AI bot to explore and gather resources in Minecraft

👤 Minecraft players who want automated resource gathering ⏱ ~20 min beginner

使うタイミング： You need resources but don't want to grind for them.

前提条件

フロー

Explore surroundings

Look around and tell me what biome we're in. Find the nearest cave entrance.✓ コピーしました

Gather resources

Go to the cave and mine all iron ore you can find. Come back and smelt it into iron ingots.✓ コピーしました

→ Mining progress updates and smelting confirmation

結果： Resources gathered and processed automatically.

トラブルシューティング

よくあるエラーと対処法

Bot can't connect to server

Ensure you opened the world to LAN (ESC → Open to LAN) and the port in your config matches the LAN port shown in chat.

確認： Check the Minecraft chat for 'Local game hosted on port XXXXX'

Bot disconnected

The Minecraft server may have kicked the bot for inactivity or invalid actions. Restart Claude Desktop to reconnect.

確認： Check Minecraft chat for kick messages

Can't place blocks — invalid position

The bot may be too far from the target position. Move closer first with move-to-position.

確認： Check bot position relative to target
