Apple Music Integration

Guide for integrating with Apple Music. Three approaches: AppleScript (direct control), UI automation (catalog without API), and MusicKit API (cross-platform).

When to Use

Invoke when users ask to:

• Manage playlists (create, add/remove tracks, list)
• Control playback (play, pause, skip, volume)
• Play an Apple Music URL (album, playlist, or song)
• 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.

AppleScript (macOS)

Zero setup. Works immediately with the Music app.

Run via Bash:

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

Multi-line scripts:

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

end tell

String Escaping

Always escape user input:

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

• macOS only — no Windows/Linux
• UI features require display — UI automation won't work headless or with Music.app minimized

UI Automation (macOS)

For catalog features without an API token. Controls Music.app through System Events (Accessibility API) and CoreGraphics (mouse events).

Requirements: Display attached, Music.app visible, Accessibility permissions for System Events (System Settings → Privacy & Security → Accessibility).

Key Concepts

System Events reads and clicks UI elements by their accessibility hierarchy:

tell application "System Events" to tell process "Music"
    -- Main content area
    scroll area 2 of splitter group 1 of window "Music"
    -- Search field
    text field 1 of UI element 1 of row 1 of outline 1 of scroll area 1 of splitter group 1 of window "Music"
end tell

CoreGraphics mouse events (via JXA) trigger hover effects that reveal hidden UI controls:

// osascript -l JavaScript
ObjC.import("CoreGraphics");
var point = $.CGPointMake(x, y);
var event = $.CGEventCreateMouseEvent($(), $.kCGEventMouseMoved, point, 0);
$.CGEventPost($.kCGHIDEventTap, event);

The Hover Trick

Music.app hides per-track Play and "Add to Library" buttons until the mouse hovers over a track row. To interact with them programmatically:

1. Find the track's UI element position via System Events
2. Move the mouse there via CoreGraphics (generates real hover events)
3. The hidden checkbox (play) and button (Add to Library) appear in the accessibility tree
4. Click them via System Events

Search via UI

1. Set the search field value: set value of searchField to "query"
2. Press Return: key code 36
3. Wait for results to load (~4 seconds)
4. Parse the "Top Results" list from scroll area 2
5. Each result is a UI element with description = name, static texts for type/artist

Note: The type separator in results uses Unicode three-per-em space (U+2004) + middle dot (U+00B7): Song꘎·꘎Radiohead

Window Recovery

Music.app can run without a window. To ensure a window exists:

tell application "Music" to activate
tell application "System Events" to tell process "Music"
    if (count of windows) is 0 then
        click menu item "Music" of menu "Window" of menu bar 1
    end if
end tell

Fragility

UI paths break when Apple updates Music.app's layout. Centralize paths as constants and test after macOS updates. Use Accessibility Inspector.app to explore the current hierarchy.

Compound flows (no API)

Recipes for replicating mcp-applemusic's catalog features without an API token. Gate each user request on "does this need catalog access?" — pure library and playback ops stay in AppleScript; only catalog lookups go through UI automation.

Add a catalog song to the user's library

If the user gave a single combined string like "Silvera - GOJIRA", split on - before searching so the catalog query gets a clean name.

1. UI search for the target (§ Search via UI)
2. Pick the first Song result whose name + artist match — do not fall back to a non-Song result; fail cleanly if no Song matched. Stale search state can lead to wrong-result clicks otherwise.
3. Get the result's element position via System Events
4. Move the mouse there via CoreGraphics to trigger hover — the hidden "Add to Library" button becomes reachable in the accessibility tree
5. Click it via System Events
6. Clear the search field so the next call starts from fresh state
7. Poll search_library via AppleScript until the track is visible locally (typical 0.5–8 s; iCloud can stall longer — cap at ~18 s, then give up cleanly)

Add a catalog song to a specific playlist

Compose "add to library" (above) → then AppleScript duplicate the new library track into the target playlist:

tell application "Music"
    set targetTrack to first track of library playlist 1 ¬
        whose name contains "Silvera" and artist contains "GOJIRA"
    duplicate targetTrack to user playlist "Road Trip"
end tell

Don't click "Add to Playlist" menu items via UI — the AppleScript duplicate path is more reliable. Even if you have a dev token, don't hit POST /v1/me/library/playlists/{id}/tracks — it returns HTTP 500 for any playlist not originally created via API (the default for playlists made in Music.app). duplicate works for any playlist.

Post-add verification

The UI path can silently click the wrong result under stale search state, and AppleScript state lags briefly after a fresh add. Always verify the expected track actually landed:

tell application "Music"
    set matches to (every track of user playlist "Road Trip" ¬
        whose name contains "Silvera" and artist contains "GOJIRA")
    return (count of matches) > 0
end tell

Retry once after a ~1 s sleep before failing. If the second verify still fails, trust it — the add did not land, surface the error instead of claiming false success.

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:

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

Common Query Parameters

Search Example

GET /v1/catalog/us/search?term=wonderwall&types=songs&limit=10

Response:
{
  "results": {
    "songs": {
      "data": [{
        "id": "1234567890",
        "type": "songs",
        "attributes": {
          "name": "Wonderwall",
          "artistName": "Oasis",
          "albumName": "(What's the Story) Morning Glory?",
          "durationInMillis": 258773,
          "releaseDate": "1995-10-02",
          "genreNames": ["Alternative", "Music"]
        }
      }]
    }
  }
}

Library-First Workflow (Complete)

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

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

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

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

Ratings

# 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:

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

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

❌ Playing catalog songs via AppleScript:

# WRONG
play track id "1234567890"

Fix: Song must be in library.

❌ Unescaped AppleScript strings:

# 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:

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:

{
  "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.
