YouTube Music Manager

ytmusic-manager

Claude Code plugin + MCP server for YouTube Music: talk to Claude (or any MCP client) to audit your liked songs, organize playlists, search, like/unlike — on your own account, from your own machine.

The killer workflow: unfiled_liked_songs finds every liked song that sits in no playlist, so your assistant can propose a filing plan and execute it in batches once you approve.

The plugin bundles the MCP server (auto-registered) and a ytmusic skill carrying the filing methodology (batching, duration checks for DJ sets, owned-playlists-only, guardrails).

How it works

• Runs locally (stdio MCP server). Nothing is hosted; no account to create.
• Uses ytmusicapi (YouTube Music's internal API — unofficial, no quota).
• Auth = your own browser session headers, stored in ~/.config/ytmusic/browser.json (chmod 600). They never leave your machine and are never pasted into a conversation.

Install

1. Capture your session

uvx --from git+https://github.com/AlexisLaporte/youtube-music-mcp-unofficial ytmusic-manager setup

The wizard asks you to paste the request headers of a POST .../youtubei/v1/... request from music.youtube.com devtools (Network tab, logged in). It validates the session and prints the account name.

2. Install the plugin (Claude Code)

/plugin marketplace add AlexisLaporte/youtube-music-mcp-unofficial
/plugin install ytmusic-manager@ytmusic

This registers the MCP server and the ytmusic filing skill in one go.

Alternative: MCP server only

For Claude Desktop or any other MCP client:

claude mcp add ytmusic -- uvx --from git+https://github.com/AlexisLaporte/youtube-music-mcp-unofficial ytmusic-manager

or in any mcpServers config:

{
  "mcpServers": {
    "ytmusic": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/AlexisLaporte/youtube-music-mcp-unofficial", "ytmusic-manager"]
    }
  }
}

Tools

Tool	Effect
whoami	check the authenticated account
list_playlists	playlists of your library
playlist_tracks / liked_songs	tracks of a playlist / your likes
search	search songs, albums, artists, playlists
unfiled_liked_songs	liked songs missing from every playlist (+ stats)
create_playlist / edit_playlist / delete_playlist	manage playlists
add_tracks / remove_tracks	fill playlists (batched)
like / unlike	rate tracks

Destructive tools (delete_playlist, remove_tracks, unlike) are guarded: the server instructs the model to get your explicit confirmation first.

Caveats

• Unofficial API: a YouTube change can break it; you use it under your own Google account and responsibility.
• Browser-session auth lives ~2 years; if whoami fails, re-run setup.
