Sound

Sound is a native macOS MCP server that lets AI tools like Claude Code, Cursor, and Windsurf search, play, and manage Apple Music through natural language.

No API keys. No browser auth flows. One command to install, one prompt to set up.

What it does

Requirements

• macOS 14+ (Sonoma or later) on Apple Silicon

• Apple Music subscription (for playback; catalog search works without one)

• An MCP-compatible AI tool (Claude Code, Cursor, Windsurf, etc.)

• For building from source: Xcode 16.3+ / Swift 6.1+

Install

Homebrew (recommended)

brew install seayniclabs/tap/sound

From source

git clone https://github.com/seayniclabs/sound.git
cd sound
swift build -c release
codesign --force --sign - --entitlements Sources/Sound/Sound.entitlements .build/release/Sound

The binary is at .build/release/Sound.

First-time setup

Run the setup command to grant Apple Music access:

sound setup

This triggers the macOS permission prompt. You only need to do this once.

Add to Claude Code

claude mcp add sound -- $(which sound)

Or add manually to ~/.claude.json:

{
  "mcpServers": {
    "sound": {
      "command": "/path/to/sound",
      "args": ["serve"]
    }
  }
}

Usage

Once connected, just talk to your AI tool:

• "Search Apple Music for Tycho"

• "Play Everlong by Foo Fighters"

• "Create a playlist called Focus and add these tracks"

• "What's playing right now?"

• "Skip to the next track"

How it works

Sound uses Apple's MusicKit framework to interact with Apple Music natively on macOS. It communicates with AI tools over stdio using the Model Context Protocol (JSON-RPC).

AI Tool  --stdio/JSON-RPC-->  Sound  --MusicKit-->  Apple Music
                                     --ApplicationMusicPlayer-->  Music.app

Auth is handled by macOS — the binary has an embedded bundle identifier (com.seayniclabs.sound) and the MusicKit entitlement. Users just click "Allow" once when prompted. No tokens, no refresh logic, no config files.

Building

swift build           # debug build
swift build -c release  # release build

Sound requires Swift 6.1+ and targets macOS 14+.
