robloxstudio

This MCP server integrates Roblox Studio with AI assistants by exposing a set of tools that let you explore game structure, read and edit scripts, and perform bulk changes locally in a safe environment. Once the Roblox Studio plugin is installed and HTTP requests are enabled in the Experience settings, you can connect your AI via popular clients (Claude, Codex, Gemini) using the provided commands. The server acts as a bridge, translating natural language prompts into Roblox Studio actions, such as inspecting the place tree, examining services and instances, listing or editing scripts, and applying bulk refactors without leaving Studio. For read-only use, you can also opt for the Inspector Edition to safely browse structure and review scripts without making changes.

To start using it, run the MCP server using the instructions above (via npx or your preferred client). Then issue prompts like asking for the game structure, locating deprecated APIs, or generating bulk edits (e.g., creating test NPCs or optimizing movement code). TheInspector Edition provides a focused, read-only toolset suitable for safe exploration, while the full server enables edits and creations within Roblox Studio through AI guidance.

Prerequisites:

• Roblox Studio installed and a plugin installed from the Studio MCP release page
• Roblox Studio Experience Settings > Security: Allow HTTP Requests enabled
• Node.js and npm installed on your machine (for npx usage)

Install and run:

1. Install the MCP server via npm/npx:
   • npx -y robloxstudio-mcp@latest
2. Ensure the Roblox Studio plugin is installed in your Plugins folder as described in the setup guide
3. Start Roblox Studio and load your project, then connect your AI client (Claude, Codex, Gemini) using the provided mcp add commands:
   • Claude: 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
4. If you encounter Windows-specific issues, you can wrap the command as shown in the Windows example, which uses cmd to run npx behind the scenes.

Verification:

• After connecting, the plugin should display as Connected in Roblox Studio, and your chosen AI client should be able to issue prompts to explore or modify the game.

Notes and tips:

• The main MCP server is designed for safe local exploration and targeted edits within Roblox Studio via AI prompts.
• For read-only exploration, consider using the Inspector Edition (robloxstudio-mcp-inspector) which exposes 21 read-only tools such as get_file_tree, get_script_source, and get_project_structure.
• If you run into connectivity issues, ensure the Roblox Studio plugin is properly installed and HTTP requests are enabled in the Experience settings.
• The example configurations show multiple ways to invoke the MCP server (npx by default, and cmd wrapper for Windows users). You can adapt the command to your environment or automation setup.
• When using AI prompts to perform edits, validate changes in Studio before saving to prevent unintended modifications.
