Browser Game tools (4, 1 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • opengame_create_game_blueprintwrite action

    Creates an implementation-ready vertical-slice brief with core loop, runtime recommendation, controls, build order, and scope guardrails. It does not generate code or call a hosted service.

  • opengame_list_showcases

    Returns public OpenGame browser-game references, their play links, prompt sources, dimensions, and implementation themes.

  • opengame_recommend_browser_runtime

    Chooses a practical 2D Canvas/DOM or 3D Three.js/WebGL starting point for a focused browser-game vertical slice.

  • opengame_validate_game_brief

    Checks whether a game brief identifies a loop, controls, win condition, loss/restart path, and visible feedback before implementation begins.

Install Browser Game in Claude Code, Cursor or VS Code

Runs npx -y opengame-browser-game-mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Browser Game repository's README, as published. We do not edit it. Read it on GitHub

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

Run locally

Open the HTML files directly in a browser:

~~~bash 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:

~~~bash 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:

  • OpenGame homepage
  • AI Game Maker
  • AI Game Agent
  • 3D browser games

Repository scope

Included:

  • Public playable HTML showcases.
  • Original prompts used to guide generation.
  • Links to the dedicated public OpenGame Skills catalog.
  • Links to matching OpenGame live demos and detail pages.
