Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

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": {
    "craftwire": {
      "command": "npx",
      "args": [
        "-y",
        "craftwire"
      ]
    }
  }
}

Run this in your terminal

claude mcp add craftwire -- npx -y craftwire

Open in Cursor

Or copy the settings yourself

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

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

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": {

Common questions

Is Craftwire 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 (0.10.0) reached the registry 24 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?

craftwire

This package is the MCP server (hub) of Craftwire. It lets AI agents see and drive Minecraft:

On a Fabric client: screenshots, a free camera, reading and clicking GUIs, chat, input and the HUD.
On a Paper server: console commands, JavaScript against the Bukkit API, world reads, edits and images, every event that fires, exceptions grouped into bugs, logs and plugin control.
A plugin dev loop, server-side bots that find their own path, and plugin tests written as JSON scenarios (npx craftwire test).
Profiling: which plugin or mod, listener and method makes the server or the game lag, and exact call times for one method.
Plugins and mods can add their own tools.

Set up your AI client

npx craftwire setup            # lists the clients found on this computer

npx craftwire setup codex # or: gemini, antigravity, cursor, windsurf, vscode, claude-desktop

setup adds the craftwire entry to the client's MCP config. It leaves the other entries alone and backs the file up as .bak first. For Codex and Gemini CLI it also installs Craftwire's skills. --dry-run shows the change without writing it.

Claude Code uses the plugin instead:

/plugin marketplace add uxplima/craftwire

/plugin install craftwire@uxplima

Any other MCP client runs it over stdio:

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

On Windows, use "command": "cmd", "args": ["/c", "npx", "-y", "craftwire"].

Add the game side

Get both jars from Releases:

craftwire-agent-fabric- .jar: put it in your Fabric profile's mods/ folder, with Fabric API.
craftwire-paper- .jar: put it in a Paper server's plugins/ folder.

Both connect to the hub on their own. The hub listens on 127.0.0.1 only and writes a token to ~/.craftwire/hub.json. Use one AI client with Craftwire at a time, or run npx craftwire serve (MCP over HTTP with a token) to share one hub between several clients.

No game open? The client_process tool starts a hidden client the hub runs itself. It downloads Minecraft and Fabric from their official servers on first use, then joins your dev server, which needs online-mode=false, or opens a singleplayer world.

Troubleshooting: npx craftwire doctor. Add --server to check a server folder too.
