About browser-game

023D and 2D game examples
03Related prompts and project links
04Local read-only MCP server

Use cases

01Explore a 3D bridge scene
02Try a Canvas platform game

04Validate a game brief

MCP support

The repository includes a local, read-only OpenGame Browser Game MCP server. AI clients can use it to scope a game vertical slice, choose Canvas/DOM or Three.js/WebGL, validate a brief, and find public showcases; it needs no API key and does not connect to OpenGame production systems.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config

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

Run commandnpx -y opengame-browser-game-mcp

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

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.

Showcases

Showcase	Type	Play	Video	Prompt	OpenGame page
Golden Gate Bridge — 3D Cinematic	3D / Three.js / WebGL	Live demo	Video preview	Prompt	OpenGame page
Vaporwave Platformer — Night City	2D / Platformer / Canvas	Live demo	—	Prompt	OpenGame page
PokeBonk: Pocket Survivor (showcase copy)	3D / Survival / Three.js	Play and guide	—	Brief and revision	OpenGame page

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

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
