OGSync

AI agent framework for Roblox Studio: a token-lean MCP server, two-way live script sync, and a self-installing Studio plugin — one binary.

• MCP server — replaces the official Roblox Studio MCP (and covers the ~100-method community surface) with ~20 consolidated, batch-first tools designed for minimal token usage.

• Two-way sync — filesystem ⇄ Studio, live, including Team Create collaborator edits. Rojo-compatible project format.

• Zero-friction install — the CLI installs and hot-updates the Studio plugin automatically; the CLI updates itself from GitHub Releases.

Install

Download the binary for your platform from Releases, unzip it, and put it on your PATH. It updates itself from then on.

Quick start

cd my-roblox-project
ogsync init      # scaffold ogsync.toml + default.project.json + src/ (skip if you already use Rojo)
ogsync serve     # daemon: MCP over stdio + Studio bridge + two-way sync

serve installs the Studio plugin on first run. Restart Studio so it picks the plugin up, then open your place — the OGSync button in the Plugins tab shows the connection panel.

Register it with Claude Code:

claude mcp add ogsync -- ogsync serve

or by hand:

{ "mcpServers": { "ogsync": { "command": "ogsync", "args": ["serve"] } } }

When something is not connected

ogsync doctor

Checks the project file, the installed plugin, the daemon, the Studio binding and sync state, and tells you the next action for anything failing.

Choosing which Studio instance to drive

With several places open, pin one in ogsync.toml — the daemon binds to exactly that session and never touches the others:

[bind]
target_place = "MyPlace"   # place name or place id
