Overview

Description from the maker (original English)

Build, play-test with screenshots, and ship three.js browser games on GrowBlocks.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Games, sports, food & learning

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • The registry lists no key to fill in.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "growblocks": {
      "command": "npx",
      "args": [
        "-y",
        "growblocks",
        "mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add growblocks -- npx -y growblocks mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "growblocks": {
      "command": "npx",
      "args": [
        "-y",
        "growblocks",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "growblocks": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "growblocks",
        "mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is GrowBlocks Dev Kit safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.0) reached the registry 23 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

GrowBlocks Dev Kit for Claude, Cursor and other AI assistants

Make a browser game with an AI assistant and ship it on GrowBlocks: three.js, Rapier physics, characters, multiplayer rooms and hosting, with no setup.

The assistant reads the API, writes game.js, plays the game headless and looks at a screenshot after every change, reuses parts other developers published (blocks), and pushes an unlisted test build you can share. Nothing goes public until you submit it and GrowBlocks reviews it.

Install

Claude Code (plugin: tools + skill)

/plugin marketplace add Gioluan/growblocks-devkit

/plugin install growblocks@growblocks

Claude Code (just the MCP server)

claude mcp add growblocks -- npx -y growblocks mcp

Claude Desktop: download growblocks.mcpb from the latest release and open it.

Cursor / Windsurf / any MCP client

{ "mcpServers": { "growblocks": { "command": "npx", "args": ["-y", "growblocks", "mcp"] } } }

Terminal: npx growblocks new my-game, then npx growblocks help.

Then ask: *"Make me a GrowBlocks game where frogs race across lily pads"*, or use the make_game prompt.

Tools

ToolWhat it does
growblocks_docsThe Dev Kit API (or one section of it)
growblocks_checkStatic checks; with play it plays the game headless and returns a screenshot
growblocks_new_gameA new game folder from the starter kit
growblocks_blocks, growblocks_block_info, growblocks_add_blockFind and add published blocks (their authors earn when your game ships them)
growblocks_login, growblocks_whoamiSign in with a code you confirm in your browser
growblocks_create_game, growblocks_link_game, growblocks_update_gameMake the game on GrowBlocks and set its name, logo and details
growblocks_pushUpload an unlisted test build and get its link
growblocks_status, growblocks_gamesBuilds, links and the review note
growblocks_submit, growblocks_publish_blockOnly when you ask: submit for review, publish a block

Every tool takes dir, the game folder. Prompts: make_game, ship_game. Resources: llms.txt, gb.d.ts.

Money (collections, the coin, earnings) never goes through the assistant: it stays in your browser at growblocks.xyz. Developers keep 70% of the fees their game generates.

Layout

  • .claude-plugin/marketplace.json: this repo as a Claude Code plugin marketplace
  • plugins/growblocks/: the plugin (.mcp.json runs npx growblocks@1.2.0 mcp, pinned so every install runs the reviewed version, plus the growblocks-game skill)
  • desktop/: the Claude Desktop extension; build it with npx @anthropic-ai/mcpb pack desktop growblocks.mcpb
  • server.json: the entry for the official MCP Registry
  • TERMS.md: the Dev Kit terms

The server is one dependency-free file, growblocks.mjs, published on npm as growblocks.
