Roblox Studio
Turn on Studio’s extra powers
Switch on Roblox Studio’s built-in MCP server so your AI can playtest, read the console, take screenshots, and add assets.
Bricklayer edits your scripts through its own plugin, and that part works on its own. Turning on Studio’s MCP server adds the rest. You do it once, and it stays on for every game.
What it unlocks
Playtesting
Your AI can start and stop a playtest, then 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 drop in models, images, and meshes.
Enable it (one time)
You do this once, inside Roblox Studio. Studio’s own interface can’t be switched on for you, so these five steps are the only part of setup you do by hand.
Open the Assistant panel
In Roblox Studio’s top toolbar, click Assistant. A panel opens on the right side of Studio.
Open its “…” menu
At the top-right of that Assistant panel, click the … (three-dots) menu.
Choose “Manage MCP Servers”
Pick Manage MCP Servers from the menu that appears.
Turn on “Enable Studio as MCP server”
Flip the toggle on. If Studio asks for permission, click Allow.
Confirm the green dot
You’ll see a green indicator with a connected-client count. That means it’s live.
Don’t see “Manage MCP Servers”?
That menu ships in recent Studio versions. If you don’t see it, update Roblox Studio (close it and reopen it, and it updates itself), then try again. The toggle lives in the Assistant panel, under its “…” menu.
Do I have to?
No. It’s optional. With it off, Bricklayer still mirrors and edits your scripts as real files, and your AI can write code. You just won’t get playtesting, console output, screenshots, or asset insertion until it’s on. Most people turn it on so their AI can see what it’s building.
