Roblox Studio Mcp Server [official]

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.
