Introducing the Astrocade MCP: Make Games With Your AI Agent

You can already build games with the AI agents you use. Now you can build even better ones and publish them to millions of players.

Every game on Astrocade starts the same way: with an idea and the words to describe it. Type it in, and within minutes you have something people can play.

For a lot of games, a few words are all it takes. Some creators want more control: bigger levels, deeper systems, and their own hands on every detail.

Today we're launching the Astrocade MCP, a hosted MCP server that connects Astrocade to the AI agents you already work with, like Claude Code, Codex, Cursor, ChatGPT, and Claude. Build in the agent you know best and publish straight to the Astrocade feed. It's live now, and there's nothing to install. Skip to setup

Why we built the Astrocade MCP

Creators already build games with AI agents like Claude Code and Codex, but a game built on a laptop doesn't have players. Hosting it, getting it in front of people, and finding out what they think is still up to the creator.

Astrocade already handles that part. Millions of players discover new games in the Astrocade feed every day, and creators grow an audience with followers, comments, and analytics. So we brought Astrocade to the agents you already use.

MCP (Model Context Protocol) is an open standard that lets AI agents plug into other apps. Connect Astrocade to your agent, and you can build games and publish them, all through your own Astrocade account.

Making a game from a prompt on Astrocade's app is still the fastest way from idea to playable. The Astrocade MCP is another way to build on Astrocade, and one especially suited to power users, traditional developers, and people eager to experiment on the frontier of what's possible. Use whichever one fits the game you want to make and your approach to creation.

What you can do with the Astrocade MCP

Connect once, and you can build, change, and publish Astrocade games right from your agent. You decide what the game should be, and your agent writes and tests the code.

Build games with more moving parts

Describe the whole game, then keep going. Plan the systems, set the rules, and shape every detail while your agent writes the code, tests it, and fixes what breaks. Try something like:

"Make a fighting game with a capybara and a pig."

Then keep shaping it: "Change the pig's weapon." "Add a lava map." "Make the pillow hit harder." Every game follows Astrocade's game guidelines, so it's built for the phones and internet connections our players use.

Pick up where you left off

Open the games already in your Astrocade account, change them, and save the new version back. Start a game from a prompt on Astrocade's app, then take it further in Claude Code, or go the other way.

Publish to millions of players

When it feels right, publish it with one command through MCP. Once it passes review, it shows up in the feed, starts collecting plays and comments, earns you followers, and comes with the same analytics dashboard as every other game on Astrocade.

How to set up the Astrocade MCP

The Astrocade MCP is hosted, so setup is one link and a sign-in. Most creators are done in about two minutes.

1. Add the Astrocade MCP to your AI agent. Everything runs through one link: https://mcp.astrocade.com/mcp.
2. Sign in to Astrocade when your agent asks, and click Allow.
3. Describe your game, then keep changing it until it feels right.
4. Publish it to Astrocade.

Here's where the link goes in each agent:

• Claude Code: In your terminal, run claude mcp add --transport http --scope user astrocade https://mcp.astrocade.com/mcp. Then in Claude Code, type /mcp and choose Authenticate.
• Codex: In your terminal, run codex mcp add astrocade --url https://mcp.astrocade.com/mcp, then sign in in the browser tab that opens.
• Cursor: Open ~/.cursor/mcp.json and add the link as an astrocade server. Then in Cursor, open Customize and click Connect next to astrocade.
• Claude (web, desktop, and mobile): In Claude on the web or desktop, go to Customize → Connectors → Add → Add custom connector, then paste the link.
• ChatGPT (web): In ChatGPT on the web, go to Plugins → Browse directory → Add → Add custom MCP server, paste the link, and set Authentication to OAuth.
• Gemini CLI: In your terminal, run gemini mcp add --scope user --transport http astrocade https://mcp.astrocade.com/mcp. Then in Gemini CLI, type /mcp auth astrocade.
• Any other agent: In your agent's settings, add the link as a remote MCP server.

Step-by-step guides for each agent are on the Astrocade MCP page.
