Roblox Studio

Roblox's official plugin for AI assistants. Build, script, playtest, and debug your Roblox experiences by talking to your assistant, connected live to Roblox Studio.

Available for Claude (Claude Code and Cowork) and ChatGPT (the ChatGPT desktop app and Codex).

Install

Claude Code: run /plugin, search for Roblox Studio, and install it.

Claude desktop app (Cowork): go to Customize → Plugins, find Roblox Studio, and install it.

ChatGPT desktop app: open Plugins, find Roblox Studio, and install it. Then start a new chat.

Codex CLI:

codex plugin marketplace add Roblox/roblox-studio-agent-plugin

Then open /plugins, install Roblox Studio, and start a new thread with /new.

Get connected

Ask your assistant:

"Get me set up with Roblox Studio."

It checks what's missing and asks you once. Then it installs and opens Studio if needed. You sign in, open a place, and turn on Studio's MCP server with one switch, and it tells you exactly where. If you need to start a new chat partway through, say "continue Roblox setup" to pick up where you left off.

Verify it worked

Ask "list my open Roblox Studio windows". Your assistant should name the place you have open.

• Claude Code: /mcp lists plugin:roblox-studio:macos and plugin:roblox-studio:windows. Only the one for your OS connects, so the other showing as failed is expected.
• Codex: codex mcp list shows Roblox_Studio.

Manual setup

If you'd rather set up Studio yourself:

1. Install Roblox Studio, sign in, and open a place.
2. Open Assistant, select … → Settings → MCP Servers (Manage MCP Servers in older versions), and turn on Enable Studio as MCP server.
3. ChatGPT and Codex only: in the same pane, under Quick Connect, turn on ChatGPT (codex). Then restart ChatGPT or open a new Codex thread.

Usage

Before you start: your assistant changes your place directly. It edits scripts, adds and removes objects, and runs Luau in Studio. Not every change can be undone from Studio, so save or publish a version of your place before asking for bigger changes.

Once you're connected, just describe what you want:

"I've never used Roblox Studio. Get me set up so you can help me build a game."

"Look at my game and tell me how the round system works."

"My coin pickup doesn't add to the leaderboard. Playtest it, find the bug, and fix it."

"Add a lobby with four spawn pads and a sign that shows the player count, then playtest it."

For Roblox-specific know-how, your assistant uses the skills built into your version of Studio.

Studio tools your assistant can use

Read-only: list_roblox_studios, get_studio_state, get_console_output, script_read, script_search, script_grep, search_game_tree, inspect_instance, screen_capture, http_get (Roblox documentation only), skill, search_asset, wait_job_finished, store_image.

Change your place or account: execute_luau, multi_edit, insert_asset, generate_mesh, generate_material, generate_procedural_model, generate_texture, segment_mesh, upload_image, start_stop_play, character_navigation, user_keyboard_input, user_mouse_input, subagent.

Works with

• Roblox Studio on macOS or Windows
• Claude Code, or Cowork in the Claude desktop app
• The ChatGPT desktop app (macOS or Windows), or the Codex CLI

Studio's MCP server runs on your computer, so claude.ai on the web and ChatGPT web and mobile can help you plan and write Luau, but can't connect to Studio.

What this plugin runs and sends

The plugin contains no code of its own, only configuration and skill instructions.

• Runs Roblox Studio's own MCP server, installed with Studio: StudioMCP in RobloxStudio.app on macOS (in /Applications or ~/Applications), or %LOCALAPPDATA%\Roblox\mcp.bat on Windows. Claude starts it through /bin/sh or cmd.exe. In ChatGPT and Codex, setup registers it as Roblox_Studio.

• During setup, after one approval from you, it may:

  • download the Studio installer from setup.rbxcdn.com, check Roblox's signature, and run it
  • open Studio
  • in ChatGPT and Codex, register the Roblox_Studio server

  You turn on Studio's MCP server yourself; it doesn't edit Studio's settings files. It asks whether you're signed in rather than checking, never closes Studio itself, and never handles your password. Security notes explain each step in detail.

• Sends to Roblox, under your Studio account, only when your assistant uses these tools: Creator Store search and insert, AI generation, image uploads, and Roblox documentation fetches.

• Sends to your AI provider whatever tool results your assistant reads, such as scripts, properties, console output, and screenshots, as part of your conversation.

• Collects nothing itself: no telemetry, and no stored data.
