Overview

Description from the maker (original English)

Local tools for planning and validating focused browser-game prototypes.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Web & browsers

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "browser-game": {
      "command": "npx",
      "args": [
        "-y",
        "opengame-browser-game-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add browser-game -- npx -y opengame-browser-game-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "browser-game": {
      "command": "npx",
      "args": [
        "-y",
        "opengame-browser-game-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "browser-game": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "opengame-browser-game-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Browser Game safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.3) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

In the same category: Browser Use, Chrome DevTools MCP, MCP Server Browser

OpenGame Showcases

Public browser-game showcases from OpenGame.

Website: https://opengame.app/

Featured preview

Golden Gate Bridge — 3D Cinematic

Click the poster to play the live demo, or watch the video preview.

This repository is intentionally small. It contains public showcase material only: playable static HTML examples, prompts, and links to the matching OpenGame pages. It does not contain OpenGame production runtime code, deployment configuration, credentials, user data, billing data, or analytics exports.

Run locally

Open the HTML files directly in a browser:

open showcases/golden-gate-bridge/index.html

open showcases/vaporwave-platformer/index.html

The Golden Gate Bridge showcase imports Three.js from jsDelivr. The Vaporwave Platformer is self-contained.

OpenGame Skills

Reusable public Skills now have a dedicated canonical repository: opengameapp/OpenGame-skills. Install them from that source:

npx skills add opengameapp/OpenGame-skills \

--skill opengame-browser-game-builder

npx skills add opengameapp/OpenGame-skills \ --skill opengame-marketplace-publisher

The legacy skills/ folder is retained temporarily so existing marketplace source links do not break during migration. New Skills and future versions are maintained only in the dedicated repository. See its Skill catalog.

OpenGame MCP servers

The mcp/ directory contains independently installable Model Context Protocol servers. The first server, OpenGame Browser Game MCP, gives AI clients deterministic tools to scope a browser-game vertical slice, choose Canvas/DOM or Three.js/WebGL, validate a brief, and discover these public showcases. It is local, read-only, requires no API key, and never connects to OpenGame production systems.

Install it from the public npm package or find io.github.opengameapp/browser-game in the Official MCP Registry. It is also listed on LobeHub Market. See the MCP publishing guide for the versioned release process.

Remix with OpenGame

Use the prompt files in prompts/ as starting points, then remix them with OpenGame on the official website:

Repository scope
