## What it does

Roblox Studio ships an MCP server over `stdio` — a local process that proxies client requests into the open session. The skill walks through enabling it in Studio (Assistant → ⋯ → Manage MCP Servers → Enable Studio as MCP server), connecting a client via quick connect or a manual config, and verifying the link by reading the game tree.

Tools come in groups: scripts (`script_read`, `multi_edit`, `script_search`), data model (`search_game_tree`, `inspect_instance`), Luau execution (`execute_luau`), assets (`generate_mesh`, `insert_asset`), playtesting (`start_stop_play`, `get_console_output`, `screen_capture`) and input simulation. With Script Sync the split is simple: disk-to-Studio file syncing stays with Script Sync, everything else — Explorer selection, model insertion, `StarterGui`, running commands — goes through MCP.

Multiple open windows are handled by `list_roblox_studios`, which returns instance IDs; pass `studio_id` on every later call instead of trusting a shared active window. You need an up-to-date Studio, a Roblox account and a client that speaks `stdio`. Treat `execute_luau` as privileged code — it can publish places and write to DataStores, so a test place or a version-controlled project is the sane default.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add nonlooped/roblox-suite --skill roblox-mcp -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/roblox-mcp/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/roblox-mcp/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add nonlooped/roblox-suite --skill roblox-mcp -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/roblox-mcp/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add nonlooped/roblox-suite --skill roblox-mcp -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/roblox-mcp/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install nonlooped/roblox-suite roblox-mcp
```

2. **Manually: put the files in place**
- File: `.github/skills/roblox-mcp/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add nonlooped/roblox-suite --skill roblox-mcp -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/nonlooped/roblox-suite --path roblox-mcp
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/roblox-mcp/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add nonlooped/roblox-suite --skill roblox-mcp -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/nonlooped/roblox-suite/tree/HEAD/roblox-mcp/SKILL.md

## When to use it
- read the object tree of an open place
- edit scripts in containers Script Sync misses
- run a Luau snippet and pull the output
- start a playtest and grab a screenshot
- pick the right window among several open Studio instances

## Example prompts
- Connect to Roblox Studio over MCP and list what's in Workspace.
- Start play mode, press space and show me the console output.
- Find every script named Door in the game tree and show its contents.

The official Roblox Studio MCP server lets a connected AI client inspect and edit an open place. It provides tools for scripts, instances, Luau execution, assets, and playtesting.

## What the Studio MCP server is

Roblox Studio implements a **Model Context Protocol (MCP)** server using `stdio` transport. The server runs as a local process on your machine and proxies requests from a supported AI client into the active Studio session. It is the bridge between your editor's agent and Studio: Script Sync handles disk-to-Studio file syncing, while MCP handles everything else (Explorer selection, instance inspection, script editing, Luau execution, play mode, input simulation, and asset insertion).

## Prerequisites

1. **Latest Roblox Studio**. Update through the launcher or download from the [Creator Hub](https://create.roblox.com/docs/studio/setup).
2. **An MCP-capable AI client**. Cursor, VS Code with Claude Code, Claude Desktop, Codex CLI, Gemini CLI, Antigravity, or any client that supports `stdio` transport.
3. **A Roblox account** signed into Studio.
4. **Git** (recommended) for the file-based workflow.

## Enabling the server in Studio

1. Open Studio and load the place you want the agent to work on.
2. Open **Assistant** (button in the upper right).
3. Click **⋯ → Manage MCP Servers**.
4. Turn on **Enable Studio as MCP server**.
5. The panel shows quick-connect options and manual configuration snippets. A green indicator appears when a client connects.

If you do not see MCP options, restart Studio after updating to the latest version.

## Connecting your client

Choose the method that matches your client:

**Quick connect** supports Antigravity, Codex CLI, Claude Code, Claude Desktop, Cursor, Gemini CLI, and Visual Studio Code.
1. In Studio: **Assistant → ⋯ → Manage MCP Servers → Quick connect**.
2. Turn on your installed client.
3. Restart the client if the tools do not appear immediately.

For clients that read an `mcp.json` or similar config file, see [references/setup-and-connection.md](references/setup-and-connection.md) for per-OS, copy-paste configurations.
