My AI cannot playtest, read errors, or take screenshots

Bricklayer edits your scripts through its own plugin, and that works on its own. But to see your game, your AI needs Studio's built-in MCP server switched on. It is a one-time toggle that stays on for every game.

What it unlocks

• Playtesting. Your AI can start and stop a playtest and watch what happens.
• Console and errors. It reads Studio's Output, so it sees runtime errors and can fix them.
• Screenshots. It can capture the viewport to check how something looks.
• Assets. It can search the Creator Store and add models, images, and meshes.

Turn it on

Studio's own settings cannot be switched on for you, so this is the one part of setup you do by hand.

1. In Roblox Studio's top toolbar, click Assistant. A panel opens on the right.
2. Click the … (three dots) menu at the top-right of that panel.
3. Choose Manage MCP Servers.
4. Turn on Enable Studio as MCP server. If Studio asks for permission, click Allow.
5. Look for a green indicator with a connected-client count. That means it is live.

Do I have to?

No. With it off, Bricklayer still syncs your scripts and your AI can still write code. You just will not get playtesting, console output, screenshots, or asset insertion. Most people turn it on, because an AI that can see its own errors fixes them much faster.

Try it

Once it is on, ask:

Start a playtest, wait a few seconds, then read the Output window and tell me about any errors.
