Roblox Super MCP

Roblox Super MCP is a Node.js MCP server that connects an MCP client to the official Roblox Studio MCP process. It adds discovery, inspection, auditing, atomic script edits, verification, and rollback-oriented tools.

Requirements

• Windows

• Roblox Studio with the official StudioMCP.exe

• Node.js 18 or newer

• An MCP-compatible client

Install and test

From the project directory, run:

npm install
npm test
node server.js

The server communicates over standard input and output. Stop the manual test with Ctrl+C after confirming it starts successfully.

Replace an existing MCP launcher

If your current setup starts the original MCP through an mcp.bat file:

1. Back up the existing launcher.

2. Replace its contents with:

   @echo off
   cd /d "<path-to-this-project>"
   node server.js

   Replace <path-to-this-project> with the folder where you cloned this repository. Keep the quotes if the path contains spaces.

3. Restart the MCP client and Roblox Studio connection.

Do not print diagnostic messages to standard output. MCP messages use that stream; diagnostics should go to standard error or a log file.

Configure an MCP client directly

You can configure the client without a batch file. Add this server entry and replace the example path with the location of your local clone:

{
  "mcpServers": {
    "roblox-super-mcp": {
      "command": "node",
      "args": ["<path-to-this-project>/server.js"]
    }
  }
}

Use forward slashes in JSON paths, or escape Windows backslashes as \\.

How it works

When started, the server locates the newest Roblox StudioMCP.exe in the current Windows user's Roblox installation, starts it, and forwards validated MCP requests to it. The available tool definitions are registered in tool_registry.js; implementation helpers live in the tools directory.

Updating

Pull the latest version, test it, and restart the MCP client:

git pull
npm install
npm test

Keep a backup of the previous launcher until the replacement has been tested in Roblox Studio.
