Short answer
Oneshot Gems is a browser game platform from Levy Street’s company: a swipeable feed of instantly playable 2D and 3D games. Anyone can play free. Creators can describe a game in plain language, play the result and keep improving it, or remix existing games, and developers can build and upload games from their own coding tool through the Oneshot Gems Game Maker MCP server.
- Games run instantly in the browser in an isolated sandbox.
- Generated games go through quality and safety checks before joining the shared library.
- Developers can publish from Claude Code, Codex or Cursor via an MCP server.

What it is
Oneshot Gems treats games like short videos: open it, swipe, and the next game is already running. The library spans quick 2D and 3D games across genres, playable on desktop or phone with no install. Players send “Gem” reactions to favourites and follow creators.
Making games with AI
The more interesting half is creation. A creator describes a game idea in plain language, plays the result, and keeps improving it by describing changes. Existing games can be remixed the same way. For developers, the Oneshot Gems Game Maker is an MCP server that gives a coding agent the platform’s SDK, guidelines and base assets, so a game can be built in Claude Code or Codex and uploaded directly.
- Players
- Free, instant play in the browser with ads; reactions, follows and a library to explore.
- Creators
- Paid plans to generate and remix games by prompt, using credits.
- Developers
- Build with their own coding agent through the MCP server; local uploads need no credits.
- Safety
- Games run in an isolated sandbox, and generated games pass quality and safety checks before joining the shared library.
What it shows
Oneshot Gems puts two ideas from our other work into one product. From World of ClaudeCraft: AI coding agents can build real, playable software quickly when the structure around them is good. From Idyllic: consumer generative AI needs moderation, cost control and a reason to come back. The MCP server is also a practical example of the pattern we use to connect AI agents to business systems, covered in MCP for business systems.
