OSCAR MCP server

OSCAR - Visit our website

OSCAR is a tool to create beautiful graphical user interaces (GUIs) to send OSC messages and control interactive installations (Modul8, MapMapper, Resolume arena, TouchDesigner, Ableton Live, Processing, Pure Data, Unity, Unreal Engine, etc). Let's create beautiful, responsive and touchable interfaces.

Build a layout in the browser, drop in buttons and sliders, point each one at an IP, port and OSC address, then publish it and open it from a phone or tablet on the same network to drive your software, gear and lights.

Download

Get the installer for your machine from the latest release:

These builds aren't code signed, so your system warns you the first time. On Windows, click More info then Run anyway. On macOS, right-click the app and choose Open.

The first time OSCAR is opened in a browser, the canvas shows the Showcase template, where every widget works, so there is something to try straight away. After that the canvas is whatever you left on it, including empty. It is a template like any other: open File → Open project or template… to get it back, or to start from another.

Keep in touch

Sign up to the OSCAR mailing list to hear about new releases, features and tutorials.

OSCAR is a free and open source project, and it is better for every bit of feedback it gets. If you build something with it, we would love to know.

Running from source

Requires Node.js 18 or newer.

git clone https://github.com/trafalmejo/OSCAR
cd OSCAR
npm install     # also installs the browser libraries under public/
npm start       # builds the bundle and starts the server

OSCAR opens your browser at http://localhost:8080 and also prints a LAN address such as http://192.168.1.20:8080. Open that second address on a phone or tablet on the same Wi-Fi to use the interface from there.

Make sure your firewall allows communication between devices on the network.

Useful commands

Running on explicit ports

To run a second copy of OSCAR on one machine -- while developing next to a running show, say -- every port has to move, including the two source ports OSC is sent from. serve:at takes the HTTP port and derives the rest from it, so one number keeps a copy out of everyone else's way:
