Install

**1. The plugin**

npx -y @el4cteo/rbx-studio-mcp --install-plugin

Or drop `StudioMCP.rbxmx` from [Releases](https://github.com/EL4CTEO/rbx-studio-mcp/releases) into your Studio plugins folder.

**2. The server**

claude mcp add roblox-studio -- npx -y @el4cteo/rbx-studio-mcp

Other clients

Codex CLI:

codex mcp add roblox-studio -- npx -y @el4cteo/rbx-studio-mcp

Cursor, Claude Desktop, Gemini CLI, Windsurf — add to their config file:

{
  "mcpServers": {
    "roblox-studio": {
      "command": "npx",
      "args": ["-y", "@el4cteo/rbx-studio-mcp"]
    }
  }
}

VS Code / Copilot (`.vscode/mcp.json`) uses `"servers"` instead of `"mcpServers"`, plus `"type": "stdio"`.

opencode (`opencode.json`):

{
  "mcp": {
    "roblox-studio": {
      "type": "local",
      "command": ["npx", "-y", "@el4cteo/rbx-studio-mcp"],
      "enabled": true
    }
  }
}

**3.** Open Studio and accept the `127.0.0.1` prompt. Check it works with `studio_status`.

Something wrong? Run `npx -y @el4cteo/rbx-studio-mcp doctor` — it says what is broken and how to fix it.

Port is **44755**, loopback only. Change it with `--port` and match it in the plugin.
