Overview

Description from the maker (original English)

Game music loops for AI agents: seamless loops with the reverb tail, Sections, and engine kits.

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: Design, images & audio

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

Run this in your terminal

claude mcp add loopsmith -- npx -y loopsmith-mcp

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "loopsmith": {
      "command": "npx",
      "args": [
        "-y",
        "loopsmith-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": {
    "loopsmith": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "loopsmith-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.

Common questions

Is Loopsmith 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 (1.0.1) reached the registry 25 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?

loopsmith-mcp

Use Loopsmith from AI apps that support MCP (the Model Context Protocol), such as Claude, Codex and Cursor.

Loopsmith prepares finished game music for game engines: seamless loops that keep the reverb tail, music in sections the game moves between, and FMOD Studio, Wwise and Unreal kits, plus ready-made players for Unity, Godot and the web. With this, an AI agent working on your game can pick up the loop points you set by ear in Loopsmith, export them into your project, and write the code that plays them.

This package is a small launcher. It finds the Loopsmith app on your computer and starts the MCP server that comes with it. Everything runs on your own computer: no account, nothing sent anywhere.

You need

  • Windows and Loopsmith installed (the full version or the free demo).
  • Node.js 18 or newer, for npx.

Without Loopsmith installed, the server offers one tool that says where to get it.

Set it up

Add this to your AI app's MCP servers:

{

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

Claude Code:

claude mcp add loopsmith -- npx -y loopsmith-mcp

Or skip this package entirely: in Loopsmith, open Help > Use with an AI app... and it adds itself to Claude, Claude Code, Cursor or Codex for you.

Then quit the AI app and open it again, and ask it to "read Loopsmith's guide".

What the AI can do

loopsmith_guide, analyze_render, check_seam, read_saved_loop, read_project, export_loop (with kit for FMOD, Wwise or Unreal), check_sections, render_join, render_walkthrough (from Loopsmith 1.19.0) and export_sections. The Loopsmith manual's "Use Loopsmith from an AI app" chapter describes each one.

Where it looks

  1. LOOPSMITH_MCP_EXE, if you set it to the full path of loopsmith-mcp.exe.
  2. The Loopsmith install Windows has on record (the full version first, then the demo).
  3. %LOCALAPPDATA%\Programs\Loopsmith and %LOCALAPPDATA%\Programs\Loopsmith Demo.

License

MIT for this launcher. Loopsmith itself is a separate, paid app with a free demo.
