Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified the GitHub account rosh-studio for this listing. That does not show the account is the product's maker.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Lets an assistant write Rosh plain-English code and compile or publish it as interactive web apps, Phaser games, and Three.js 3D scenes.

What you can do: Read the full Rosh language reference
Compile Rosh code into runnable HTML5 canvas apps, Phaser games, or Three.js scenes
Publish programs to rosh.cloud and list or fetch your programs by ID
Update, delete, hide, or unhide existing programs
When to use it: Useful when you want an assistant to build small interactive apps, browser games, or 3D scenes from plain-English instructions and host them on rosh.cloud, rather than hand-writing HTML or JavaScript.
Requirements: Runs locally over stdio, typically launched with uvx rosh-mcp (Python package). A rosh.cloud account and an API key with read and write scopes are required, supplied through the ROSH_API_KEY environment variable; ROSH_API_BASE optionally overrides the API base URL. Network access to rosh.cloud is needed.

Before you install

Every tool requires the ROSH_API_KEY credential, which grants read and write access to your rosh.cloud programs. Publishing, updating, deleting, hiding, and unhiding all change data on the remote service, and deletion is not reversible. Code and program content are sent to rosh.cloud.

Installation

In SourceWeft

Open Rosh Mcp in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

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 300set player color "blue"on key "ArrowRight" then set player x to player x + 5

create box called player at 400 300set 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):

json

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

{  "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 ROSH_API_KEY before starting the server.

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

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
