Apple Music Integration

Guide for integrating with Apple Music. Covers AppleScript (macOS), MusicKit API (cross-platform), and the critical library-first requirement.

When to Use

Invoke when users ask to:

• Manage playlists (create, add/remove tracks, list)
• Control playback (play, pause, skip, volume)
• Search catalog or library
• Add songs to library
• Access listening history or recommendations

Critical Rule: Library-First Workflow

You CANNOT add catalog songs directly to playlists.

Songs must be in the user's library first:

• ❌ Catalog ID → Playlist (fails)
• ✅ Catalog ID → Library → Playlist (works)

Why: Playlists use library IDs (i.abc123), not catalog IDs (1234567890).

This applies to both AppleScript and API approaches.

Platform Comparison

| Feature | AppleScript (macOS) | MusicKit API | |---------|:-------------------:|:------------:| | Setup required | None | Dev account + tokens | | Playlist management | Full | API-created only | | Playback control | Full | None | | Catalog search | No | Yes | | Library access | Instant | With tokens | | Cross-platform | No | Yes |

AppleScript (macOS)

Zero setup. Works immediately with the Music app.

Run via Bash:

bash
osascript -e 'tell application "Music" to playpause'
osascript -e 'tell application "Music" to return name of current track'

Multi-line scripts:

bash
osascript <<'EOF'
tell application "Music"
    set t to current track
    return {name of t, artist of t}
end tell
EOF

Available Operations

| Category | Operations | |----------|------------| | Playback | play, pause, stop, resume, next track, previous track, fast forward, rewind | | Player State | player position, player state, sound volume, mute, shuffle enabled/mode, song repeat | | Current Track | name, artist, album, duration, time, rating, loved, disliked, genre, year, track number | | Library | search, list tracks, get track properties, set ratings | | Playlists | list, create, delete, rename, add tracks, remove tracks, get tracks | | AirPlay | list devices, select device, current device |

String Escaping

Always escape user input:

python
def escape_applescript(s):
    return s.replace('\\', '\\\\').replace('"', '\\"')

safe_name = escape_applescript(user_input)
script = f'tell application "Music" to play user playlist "{safe_name}"'

Limitations

• No catalog access - only library content
• macOS only - no Windows/Linux

MusicKit API

Cross-platform but requires Apple Developer account ($99/year) and token setup.

Authentication

Requirements:

1. Apple Developer account
2. MusicKit key (.p8 file) from developer portal
3. Developer token (JWT, 180 day max)
4. User music token (browser OAuth)

Generate developer token:

python
import jwt, datetime

with open('AuthKey_XXXXXXXXXX.p8') as f:
    private_key = f.read()

token = jwt.encode(
    {
        'iss': 'TEAM_ID',
        'iat': int(datetime.datetime.now().timestamp()),
        'exp': int((datetime.datetime.now() + datetime.timedelta(days=180)).timestamp())
    },
    private_key,
    algorithm='ES256',
    headers={'alg': 'ES256', 'kid': 'KEY_ID'}
)

Get user token: Browser OAuth to https://authorize.music.apple.com/woa

Headers for all requests:

Authorization: Bearer {developer_token}
Music-User-Token: {user_music_token}

Base URL: https://api.music.apple.com/v1

    }
  }
}

Library-First Workflow (Complete)

Adding a catalog song to a playlist requires 4 API calls:

python
import requests

headers = {
    "Authorization": f"Bearer {dev_token}",
    "Music-User-Token": user_token
}

# 1. Search catalog
r = requests.get(
    "https://api.music.apple.com/v1/catalog/us/search",
    headers=headers,
    params={"term": "Wonderwall Oasis", "types": "songs", "limit": 1}
)
catalog_id = r.json()['results']['songs']['data'][0]['id']

# 2. Add to library
requests.post(
    "https://api.music.apple.com/v1/me/library",
    headers=headers,
    params={"ids[songs]": catalog_id}
)

# 3. Get library ID (catalog ID → library ID)
r = requests.get(
    f"https://api.music.apple.com/v1/catalog/us/songs/{catalog_id}/library",
    headers=headers
)
library_id = r.json()['data'][0]['id']

# 4. Add to playlist (library IDs only!)
requests.post(
    f"https://api.music.apple.com/v1/me/library/playlists/{playlist_id}/tracks",
    headers={**headers, "Content-Type": "application/json"},
    json={"data": [{"id": library_id, "type": "library-songs"}]}
)

Create Playlist

bash
POST /v1/me/library/playlists
Content-Type: application/json

{
  "attributes": {
    "name": "Road Trip",
    "description": "Summer vibes"
  },
  "relationships": {
    "tracks": {
      "data": []
    }
  }
}

Ratings

bash
# Love a song (value: 1 = love, -1 = dislike)
PUT /v1/me/ratings/songs/{id}
Content-Type: application/json

{"attributes": {"value": 1}}

Limitations

• No playback control - API cannot play/pause/skip
• Playlist editing - can only modify API-created playlists
• Token management - dev tokens expire every 180 days
• Rate limits - Apple enforces request limits

Common Mistakes

❌ Using catalog IDs in playlists:

python
# WRONG
json={"data": [{"id": "1234567890", "type": "songs"}]}

Fix: Add to library first, get library ID, then add.

❌ Playing catalog songs via AppleScript:

applescript
# WRONG
play track id "1234567890"

Fix: Song must be in library.

❌ Unescaped AppleScript strings:

python
# WRONG
name = "Rock 'n Roll"
script = f'tell application "Music" to play playlist "{name}"'

Fix: Escape quotes.

❌ Expired tokens: Dev tokens last 180 days max. Fix: Check expiration, handle 401 errors.

The Easy Way: mcp-applemusic

The mcp-applemusic MCP server handles all this complexity automatically: AppleScript escaping, token management, library-first workflow, ID conversions.

Install:

bash
git clone https://github.com/epheterson/mcp-applemusic.git
cd mcp-applemusic && python3 -m venv venv && source venv/bin/activate
pip install -e .

Configure Claude Desktop:

json
{
  "mcpServers": {
    "Apple Music": {
      "command": "/path/to/mcp-applemusic/venv/bin/python",
      "args": ["-m", "applemusic_mcp"]
    }
  }
}

On macOS, most features work immediately. For catalog features or Windows/Linux, see the repo README.
