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.

Quick Start

Claude Desktop / Claude Code

Add to your MCP config (~/.claude/mcp.json or Claude Desktop settings):

{
  "mcpServers": {
    "rosh": {
      "command": "uvx",
      "args": ["rosh-mcp"],
      "env": {
        "ROSH_API_KEY": "rosh_k1_your_key_here"
      }
    }
  }
}

Cursor / Windsurf

Same config format — add to your MCP settings file.

Get an API Key

Create an account at rosh.cloud
Go to Settings → API Keys
Create a key with read,write scopes

Note: All tools require an API key — set ROSHAPIKEY before starting the server.

Tools

Example Prompts

Try these with any MCP-capable AI:

"Build me a space shooter game" — AI reads docs, writes Rosh code, compiles to Phaser
"Create a 3D rotating sculpture" — compiles to Three.js
"Make an interactive dashboard with buttons and counters" — compiles to web
"Show me what Rosh can do" — AI calls rosh_docs and explores
