Roblox Studio MCP Server

Bridge AI assistants to Roblox Studio — 51 tools for exploring, editing, and automating your game.

Works with Claude Code, Claude Desktop, Cursor, Gemini, Codex, and any MCP-compatible client.

What It Does

An MCP (Model Context Protocol) server that gives AI full access to your Roblox Studio session. Explore game hierarchies, read and edit scripts, manipulate properties, create instances, build terrain, run playtests — all locally via HTTP polling. No external servers, no data collection.

Related MCP server: robloxstudio-mcp

Quick Start

1. Install the Studio Plugin

Option A — Creator Store (easiest): Install from Roblox Creator Store

Option B — Manual: Download MCPPlugin.rbxmx from Releases and drop it into your Plugins folder:

Windows: %LOCALAPPDATA%/Roblox/Plugins/
macOS: ~/Documents/Roblox/Plugins/

2. Enable HTTP Requests

Game Settings > Security > Allow HTTP Requests = ON

3. Connect Your AI

Claude Code:

claude mcp add robloxstudio -- npx -y robloxstudio-mcp@latest

Codex:

codex mcp add robloxstudio -- npx -y robloxstudio-mcp@latest

Gemini:

gemini mcp add robloxstudio npx --trust -- -y robloxstudio-mcp@latest

Add to your MCP config file:

{
  "mcpServers": {
    "robloxstudio-mcp": {
      "command": "npx",
      "args": ["-y", "robloxstudio-mcp@latest"]
    }
  }
}

Windows users — if you encounter issues, wrap with cmd:

{
  "mcpServers": {
    "robloxstudio-mcp": {
      "command": "cmd",
      "args": ["/c", "npx", "-y", "robloxstudio-mcp@latest"]
    }
  }
}

Plugin shows "Connected" when ready.
