studio-rust

This MCP server provides a reference implementation that enables Roblox Studio to communicate with Claude Desktop or Cursor via the MCP (Model Context Protocol). The server runs a small Rust-based web service and an internal RMCP component that talks to Claude Desktop over stdio. Tools exposed to Studio include run_code (execute code in Studio and return output), insert_model (insert a model from the Roblox Creator Store), get_console_output (retrieve Studio console output), start_stop_play (control play mode or server state), run_script_in_play_mode (execute a script in play mode and return structured results), and get_studio_mode (report whether Studio is in start_play, run_server, or stop state). To use the setup, install Roblox Studio and Claude Desktop (or Cursor), install the MCP server, then connect Claude or Cursor to the Studio MCP endpoint. You’ll be able to prompt Claude Desktop to issue tool commands to Studio and receive results or status updates in return.

Prerequisites:

• Roblox Studio installed and ready
• Claude Desktop installed (and Cursor if you use Cursor integration)
• Administrative access on your machine to install binaries

Install via release binaries (recommended for ease):

1. Go to the releases page and download the latest Windows installer rbx-studio-mcp.exe (or macOS package if on macOS).
2. Run the installer and follow the prompts.
3. Restart Claude/Desktop tools and Roblox Studio after installation.

Manual/manual build path (advanced):

1. Ensure Roblox Studio and Claude Desktop are installed and started at least once.
2. Download or clone this repository.
3. Use the provided installer or build from source as described in the repository if you prefer a custom build.
4. After installation, restart Claude Desktop and Roblox Studio.

Verify setup:

• In Roblox Studio, open Plugins and confirm the MCP plugin appears and can be toggled on/off.
• In Claude Desktop, ensure MCP configuration points to Roblox_Studio as the transport (stdio) and that the plugin is ready to communicate.

If you encounter issues, a common fix is to restart both Roblox Studio and Claude Desktop, then re-enable the MCP connection.

Notes: This MCP server is a reference implementation and is no longer actively updated; Roblox recommends using the built-in MCP Server shipped with Roblox Studio for external AI tool integration. Third-party tools interfacing via MCP may access or modify your Roblox places, so review privacy and data handling terms of any tools you use. If you’re configuring Claude Desktop with this server manually, ensure the transport is set to stdio and that the path to rbx-studio-mcp.exe is correct for your platform. Restarting Studio and Claude Desktop frequently resolves synchronization issues. The included tools expose capabilities that can read or modify your workspace, so use them with caution.
