How to make a Roblox game with Claude Code

Yes, Claude Code can make a Roblox game, once it is connected through an MCP server. On its own it can write Luau scripts as files, but a Roblox game lives in a place file that it cannot see or build. Connected to PromptBlox, it gets a whole game built, checked and saved from your description. Connected to Roblox Studio, it can test that game in play mode.

Claude Code is a coding agent that runs in your terminal. MCP stands for Model Context Protocol, an open standard for connecting AI tools to other apps. The steps on this page were checked on November 11, 2026.

What you need

• Claude Code, installed and working. Follow its install page and make sure you can chat with it first.
• A PromptBlox account. You can connect a coding agent on any plan.
• Node.js 20.3 or newer, which runs the installer.
• Roblox Studio on a Windows or Mac computer, for testing. See how to install it.

Connect Claude Code to PromptBlox

A connection lasts 90 days, and PromptBlox emails you whenever a coding agent is connected to your account. The full setup guide covers Windows, computers without a browser and common errors.

Ask Claude Code for a game

Ask in your own words. For example:

• “Make me an obby on floating islands with three checkpoints in PromptBlox.”
• “In my pizza game, make the oven bigger and add a tip jar.”
• “List my PromptBlox projects.”

Claude Code writes the plan for the world and the gameplay, then the scripts. PromptBlox turns the plan into Roblox parts, checks that every scripted object is connected to a real script, saves the game to your library and sends back pictures of the result. Claude Code can look at those and ask for fixes before it tells you the game is ready.

Claude Code does the AI work with its own account. PromptBlox still uses some of your usage allowance for the parts it runs, such as the concept image for a new game, and new games count toward your plan’s saved games.

Test the game in Roblox Studio

1. Ask Claude Code to download the game. You get a Roblox place file.
2. Open the file in Roblox Studio.
3. In Studio, open Assistant, choose Manage MCP Servers and turn on Enable Studio as MCP server. As of November 2026 the quick connect list in that panel includes Claude Code. Roblox’s Studio MCP server guide has the details.
4. Restart Claude Code, then ask it to playtest the game. PromptBlox gives it a playtest plan, it runs the plan with Studio’s own tools and reports what passed.
5. Ask for fixes as changes to the PromptBlox project, so they are saved as a new version.

Roblox says connected tools can read and modify content in your open places, so save before large changes. Our page on Roblox MCP servers compares the two connections side by side.

Why not use Claude Code on its own?

The AI is the same either way. What changes is the system around it. Working alone, Claude Code writes scripts and has to place the world part by part. Through PromptBlox, a compiler builds the world from its plan, checks run before a build can finish, and every version is saved to a project you can also open on the website. Our comparison of AI Roblox game makers explains why that matters more as a game gets bigger.

Disconnect

Run npx promptblox-mcp remove --agent claude-code to take PromptBlox out of Claude Code’s settings. To end the connection itself, revoke it on the PromptBlox Connect page. The setup guide shows where.
