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": {
    "robloxstudio-mcp-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/boshyxd/robloxstudio-mcp"
      ]
    }
  }
}

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": {
    "robloxstudio-mcp-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/boshyxd/robloxstudio-mcp"
      ]
    }
  }
}

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": {
    "robloxstudio-mcp-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/boshyxd/robloxstudio-mcp"
      ]
    }
  }
}

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": {
    "robloxstudio-mcp-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/boshyxd/robloxstudio-mcp"
      ]
    }
  }
}

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

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "robloxstudio-mcp-2",
      "command": "TODO",
      "args": [
        "See README: https://github.com/boshyxd/robloxstudio-mcp"
      ]
    }
  ]
}

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": {
    "robloxstudio-mcp-2": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/boshyxd/robloxstudio-mcp"
        ]
      }
    }
  }
}

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

claude mcp add robloxstudio-mcp-2 -- TODO 'See README: https://github.com/boshyxd/robloxstudio-mcp'

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

ユースケース

使うタイミング： You inherited a Roblox project and need to understand its structure.

前提条件

Roblox Studio with plugin installed — Copy plugin to Plugins folder, enable HTTP Requests in Experience Settings
MCP client configured — Set up Claude Desktop or Codex with the server

→ Hierarchical view of game services and major scripts
Search for patterns

Grep all scripts for references to 'DataStore' or 'RemoteEvent'. Which scripts handle player data?✓ コピーしました

→ List of scripts with matched lines and file paths

結果： A clear understanding of the game's architecture and key systems.

注意点

Large games have thousands of instances — Use search_objects and grep_scripts to focus on specific areas instead of browsing the full tree

Write and test Roblox scripts with AI assistance

👤 Roblox developers who want AI help writing Lua scripts ⏱ ~30 min intermediate

使うタイミング： You need to create or modify game scripts and want AI-assisted development.

前提条件

Full edition MCP connected — Use the full version for write access

フロー

Read existing code
