Overview

AI-generated overview

Launcher that connects an AI assistant to the Loopsmith desktop app so it can inspect, check and export game music loops and sections.

What you can do
  • Read Loopsmith's guide and inspect saved loops and projects
  • Analyze renders and check loop seams for seamless looping
  • Check sections and render joins or walkthroughs of section transitions
  • Export loops and sections, including engine kits for FMOD, Wwise or Unreal
When to use it
For game developers who already use Loopsmith on Windows and want an AI agent to pick up their hand-set loop points, export them into a game project, and write the code that plays them.
Requirements
Windows with Loopsmith installed (full version or free demo) and Node.js 18 or newer for npx. The launcher finds the app via the LOOPSMITH_MCP_EXE environment variable, the recorded install, or the default LOCALAPPDATA program folders. No account or API key.
Before you install
It is a small launcher that starts the MCP server bundled with the Loopsmith app, so it is useless without that app installed. Export tools write files into your project. Everything runs locally and nothing is sent anywhere, per the README.

Installation

In SourceWeft

  1. Open Loopsmith in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

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:

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

Claude Code:

bash
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.

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
