Overview

What is Roblox Studio MCP Server?

Roblox Studio MCP Server is a reference implementation of the Model Context Protocol that connects Roblox Studio to Claude Desktop via a plugin. It uses a Rust-based web server (axum) for long polling with the Studio plugin and an rmcp server for stdio transport with Claude. It is intended for Roblox developers who want to use Claude Desktop to automate Studio tasks.

How to use Roblox Studio MCP Server?

Download and run the installer from the releases page (or build from source with cargo run), then restart Roblox Studio and Claude Desktop. Verify setup by checking that the MCP plugin appears in Studio's Plugins tab, the console shows “The MCP Studio plugin is ready for prompts.”, and Claude Desktop lists the insert_model and run_code tools. Send prompts to Claude Desktop to modify your Studio place.

Frequently asked questions

What tools are available in this server?

Two tools are provided: `insert_model` for adding a model to the place, and `run_code` for executing Lua code in Studio.

What software do I need to run this server?

You need Roblox Studio and Claude Desktop installed and started at least once. To build from source, you also need Rust.

How does the server communicate with Roblox Studio?

A Studio plugin long polls the Rust web server (axum), which sends requests to Claude Desktop via stdio transport. The plugin posts responses back through the same polling channel.

Does the setup include a Studio plugin?

Yes, the installer or build script automatically installs the required Studio plugin and configures Claude Desktop to communicate with the MCP server.

What are the privacy implications?

This MCP server is accessed by third-party tools, allowing them to modify and read your opened place. Third-party data handling and privacy practices are subject to their own terms.
