Phaser Game Agent · MCP

Connect your coding agent

Build games from inside the editor you already use with the Phaser Game Agent MCP server.

The agent runs on credits

Building gives you your own cloud sandbox, where your projects and the Phaser Agentic Engine live. Time on it is billed per minute, and generating images and audio costs credits too. A fully featured game typically costs around 500 credits to build.

You need credits on your Phaser account before you can build.

Fastest setup

Detects your installed editors, signs you in, and writes each one’s config. Needs Node.js 20+.

Terminal
npx @phaserjs/game-agent

Then restart the editor and ask it: “Check my Phaser Game Agent account.” To set it up by hand instead, pick your editor below.

Pick your editor

Each guide has the exact steps for that client: the automatic CLI route and the manual config, with the right file path and a copy-paste snippet.

Any MCP-compatible client works. To wire up one we don’t list, run npx @phaserjs/game-agent manual to print a ready-to-paste config.

What you can ask it

You describe what you want in plain language and your agent calls the tools for you. Tap a prompt to copy it.

Three prompts, start to finish. Paste them into your agent’s chat.

  1. Prove the connection

    It greets you by name and reports your credit balance, which tells you the tool loaded and your token works.

    Check my Phaser Game Agent account

  2. Describe a game

    Your agent reads the built-in guide, opens a cloud project, reuses known-good blocks, writes the code, type-checks it and publishes a preview. You get a public playUrl when it finishes.

    Use the Phaser Game Agent: open a project and build me a Breakout clone, then preview it.

  3. Play it and ask for changes

    Open the play URL in your browser, then keep talking. Your sandbox pauses automatically after every operation, so you pay for the work it does and not for the time you spend playing or thinking.

    Make the paddle wider and add a particle burst when a brick breaks.
    Add a high-score table that survives a refresh.
    How many plays has my game had?

After the build

Finished games land in your library at /agent/games, with versions and play analytics. From there you can:

Play it

Runs in the browser. Players need no download and no account.

Share it

Every game gets a public link you can send to anyone.

Export it

Download a standalone build for Web, Windows, macOS or Linux.

Embed it

Drop it into your own site with an iframe.

Without a coding subscription of your own, you can build on the website instead: describe a game and our agent builds the whole thing. See how it works →
