What it does
Roblox Studio ships its own MCP server over stdio. Once it is turned on in Assistant settings, any MCP client can work in an open Studio session: read, search and edit scripts, run Luau in Edit, Client or Server data models, explore the instance tree, generate meshes, materials and procedural models, search and insert Creator Store assets, start and stop playtests with simulated keyboard, mouse and character navigation, capture the viewport and save the place. Quick connect sets up Claude Code, Codex CLI, Cursor, Gemini CLI, Claude Desktop, VS Code and Antigravity from inside Studio; for other clients the command is /Applications/RobloxStudio.app/Contents/MacOS/StudioMCP on macOS or cmd.exe /c %LOCALAPPDATA%\Roblox\mcp.bat on Windows. It replaces Roblox's earlier open-source studio-rust-mcp-server, archived in April 2026.
Use when
- build or fix a Roblox experience from Claude Code, Codex or Cursor
- run Luau and read the output log from an agent
- playtest a Roblox game automatically with simulated input
- generate meshes, materials or procedural models in Studio
- capture Studio viewport shots for a game trailer
Not for
- Unity, Unreal or Godot projects
- MCP clients you don't trust: they can read and change your open places
