lainbridge

lets claude code build stuff directly in roblox studio. it reads your game, edits scripts, creates instances and UI, runs lua, takes screenshots — 30+ tools. everything is undoable with ctrl+z.

you need

• node.js (click the big green LTS button, install it)
• roblox studio
• claude code

install

1. install node.js if you don't have it (click the big green LTS button)
2. download LainbridgeSetup.exe and run it
3. in your project folder, add the tools to claude code:

   claude mcp add lainbridge -- npx -y lainbridge@latest

how to use

1. double-click "Lainbridge" on your desktop (starts the bridge — leave it open)
2. open studio, go to Home > Game Settings > Security, turn on "Allow HTTP Requests"
3. click Connect in the Lainbridge panel in studio
4. open claude code — the tools are ready

every time after that

1. double-click "Lainbridge" on your desktop
2. open studio, click Connect in the lainbridge panel
3. open claude code — it just works

what can it do

just tell claude what you want. some examples:

• "add a sprint system to my game"
• "fix the gun not doing damage"
• "build a shop UI with 3 tabs"
• "make the NPC walk between waypoints"
• "show me a screenshot of the game"
• "find all scripts that use RemoteEvents"

claude reads your game state, understands how your scripts connect, makes the changes, and verifies they work.

tools

reading — get_context, read_script, get_instance, get_status, get_errors, get_console

analysis — analyze_system, get_script_deps, search_scripts

creating — create_script, create_instance, create_ui, batch_create

editing — edit_surgical, edit_lines, edit_regex, edit_script, set_properties

execution — run_lua, run_in_playtest, execute_command

visual — screenshot, capture_viewport

troubleshooting

"commands aren't working" — make sure the bridge window is open and studio shows "Connected" in the lainbridge panel.

"Allow HTTP Requests" — you need to enable this in studio every time you open a new place. Home > Game Settings > Security.

"tools not showing up in claude code" — make sure you ran claude mcp add lainbridge -- npx -y lainbridge@latest in your project folder.

"node is not recognized" — install node.js from https://nodejs.org and restart your terminal.

how it works

claude code <-> mcp server <-> bridge <-> studio plugin <-> roblox studio

the bridge keeps a copy of your game state in memory so reads are instant. edits go through the plugin which wraps everything in studio's undo system.

multiple studio instances

run bridges on different ports:

lainbridge start 9091
lainbridge start 9092

use the switch_port tool in claude code to swap between them.
