About loopsmith

loopsmith-mcp is a launcher that lets MCP-compatible AI apps use Loopsmith’s game-music tools. It helps game developers analyze loops, check sections, and export engine kits; processing runs locally.

Key features

  1. 01Analyze rendered audio
  2. 02Check loop seams and sections
  3. 03Read projects and saved loops
  4. 04Export loops and sections
  5. 05Create FMOD, Wwise, and Unreal kits

Use cases

  1. 01Check whether a game-music loop joins cleanly
  2. 02Arrange music sections for game state changes
  3. 03Export loops into a game project
  4. 04Use Loopsmith guidance to write playback code

MCP support

The launcher locates the local Loopsmith app and starts its bundled MCP server, exposing music analysis, checking, reading, and export tools to AI apps.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
  "mcpServers": {
    "composingkeys-loopsmith": {
      "command": "npx",
      "args": [
        "-y",
        "loopsmith-mcp"
      ]
    }
  }
}
Run commandnpx -y loopsmith-mcp

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Tools

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Details

From the project README

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.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
