One free plugin for Roblox Studio. Describe what you want and Synagy plans it with a price, writes the Luau, builds the world in your place and playtests it with an avatar. Or let your own agent drive Studio.
Our crew builds it for you
“An obby with five stages, checkpoints and a timer on the screen.”
Claude Code, Codex, Cursor and more
“Add a tycoon dropper that spawns a part every two seconds.”
One double-click on Windows. Studio opens with a fresh baseplate and the Synagy window.
Click “Sign in with synagy.org” and confirm the code on synagy.org/link.
An obby, a tycoon, a simulator, or a change to the place you have open.
Every part with its price in credits. Then press Build.
Scripts get written and syntax-checked, the world gets built, a playtest proves it works.
engine_run runs code in edit mode and returns output and errors with line numbers.
roblox_files reads, writes and deletes scripts by path and syntax-checks them all.
engine_logs shows the newest lines, errors marked.
roblox_play_test plays for a few seconds and returns what happened.
engine_scene lists instances, classes, positions and sizes.
engine_status says what is connected and names the missing step.
Every script gets a syntax check and every part a playtest before you see it. Errors go back to the builder, not to you.
Synagy works in the place you have open, and each change lands as one step in Studio’s undo history.
Studio asks you once to allow the connections: your own agent on this computer, and the Synagy cloud for the window.
Plugin and MCP are free. The window runs on credits, shows the price first, and a part that fails costs nothing.
“Install Synagy.cmd” puts the plugin into Roblox Studio and opens Studio with a new baseplate. The Synagy window is already on the right.
Your agent runs one installer command: plugin into Studio, MCP server into the agent, Studio opens with a baseplate. A test part proves the connection.
It is a preview. We build and test it in Roblox Studio 0.741 on Linux through Vinegar. Windows and macOS have not been tested by us yet, so the download opens in waves. Join the waitlist and we will tell you when it is your turn.
The plugin and the MCP server are free. The Synagy window runs on the credits of your synagy.org account, the same credits as in Unity and Minecraft: you see the price before it builds, and a part that fails costs nothing. With your own agent, no Synagy credits are used.
It writes scripts with their usual names (Script, LocalScript, ModuleScript) and builds parts in the open place. Every change is one undo step. Use a copy or version history for places you care about.
Not yet. In Roblox, images and meshes have to be uploaded as assets to your account first, so for now Synagy builds with parts, scripts and what is already in your place.
Claude Code, Codex, Cursor, Antigravity, Hermes and any other agent that runs a local MCP server. One installer command sets up the plugin, the MCP server and a fresh baseplate.
