Roblox Studio MCP Server

This repository contains a reference implementation of the Model Context Protocol (MCP) that enables communication between Roblox Studio via a plugin and Claude Desktop or Cursor. It consists of the following Rust-based components, which communicate through internal shared objects.

• A web server built on axum that a Studio plugin long polls.
• A rmcp server that talks to Claude via stdio transport.

When LLM requests to run a tool, the plugin will get a request through the long polling and post a response. It will cause responses to be sent to the Claude app.

Please note that this MCP server will be accessed by third-party tools, allowing them to modify and read the contents of your opened place. Third-party data handling and privacy practices are subject to their respective terms and conditions.

The setup process also contains a small plugin installation and Claude Desktop configuration script.

Included tools

• run_code - Runs a command in Roblox Studio and returns the printed output. Can be used to both make changes and retrieve information.
• insert_model - Inserts a model from the Roblox Creator Store into the workspace. Returns the inserted model name.
