Rosh Mcp

Rosh MCP Server

Give any AI the power to create and publish interactive web apps, games, and 3D scenes using Rosh — a plain-English programming language.

What is Rosh?

Rosh lets you write programs in plain English:

create box called player at 400 300
set player color "blue"
on key "ArrowRight" then set player x to player x + 5

This compiles to a runnable HTML5 canvas app, a Phaser game, or a Three.js 3D scene — depending on the target.
