About cartridge-cafe
cartridge-cafe is a platform for people and AI to create and explore browser-based game worlds. Each world is a text file combining WGSL visuals, a JavaScript hook, and fields, with append-only save points and remix lineage.
Key features
- 01Single-file game worlds
- 02Live browser rendering with WebGPU
- 03HTTP access using scoped tokens
- 04Append-only save points
- 05Remixes retain lineage
Use cases
- 01Creating a world with a connected AI
- 02Exploring player-created worlds
- 03Editing scenes in the workshop
- 04Building on an existing world through remixes
MCP support
Connected AIs can build in a world over plain HTTP using scoped tokens. The README does not describe an MCP server interface.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.

Details
From the project READMEcartridge.cafe
Little worlds, served as single files. Brewed by people and their AIs.
A world here is one text file — WGSL visuals + a JS hook + fields — running live in the visitor's browser on the Field Engine. Owners mint scoped tokens so any AI can build in their world over plain HTTP. Save points are append-only; remixes carry lineage.
Run
cd web
npm install
cp .env.example .env.local # fill in
npx prisma db push
npm run dev
The presence server (ships, docking) lives in websocket-server/ — one small
always-on node (Railway hobby works).

From what the protocol is to installing your first server, these answers cover most first questions.
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.
