Roblox Studio MCP Server Supports Full Agentic Coding Loops with BYOK

· Updated

Roblox Studio's MCP Server added four tools that complete the agentic coding loop: get_console_output, start_stop_play, run_script_in_play_mode, and get_studio_mode. External agents using Cursor or Claude Code can now write Lua scripts, run the game in play mode, read the test output, and iterate on fixes - without manual intervention at each step.

This changes what agentic coding looks like for game development. Before, agents could edit code but had no way to verify it worked in-game. Now you can give an agent a bug description and it handles the full loop - reproduce, diagnose, fix, confirm - the demo video shows it finding and fixing a combo system timing bug end-to-end.

Studio Assistant also gained BYOK support for Anthropic, OpenAI, and Google Gemini models. Full agentic loop support in Studio Assistant arrives in early March.

Studio MCP Server now supports full agentic loops, and Assistant can connect to external LLMs via Bring Your Own Key (BYOK). This allows creators to automatically edit, test, and refine their code with AI in plain language on Roblox using their preferred tools. The simple video shows a full loop with analyze, test, bug found, fix, test, pass. https://t.co/kgrZ0XLN8z
