Music Lyrics MCP Server

Ask Claude to analyze the song you're currently listening to LIVE on Spotify, and it will automatically look up what's playing and fetch the lyrics.

If you listen to mumble rap as much as me, you might find this useful. Sometimes, I just lost track of what the artist is singing, but I keep following because the flow is so good:)

How it works

1. You play music in Spotify
2. Last.fm detects what's playing and logs it in real-time
3. Claude reads that from Last.fm, fetches the lyrics from Genius, and answers your question

Prerequisites

• Claude Desktop (Windows or Mac)
• A Last.fm account with Spotify connected for scrobbling
• A Genius API token
• Python 3.10+

Setup

1. Install dependencies

pip install -r requirements.txt

2. Configure credentials

cp .env.example .env

Fill in .env with your Last.fm API key, secret, username, and Genius token.

3. Connect Spotify to Last.fm

Go to https://www.last.fm/settings/applications and connect Spotify. This enables scrobbling — Last.fm will track what you play in Spotify automatically.

4. Get a Last.fm API key

Go to https://www.last.fm/api/account/create. Leave the callback URL blank. Copy the API key and shared secret into .env.

5. Register with Claude Desktop

On Windows (Microsoft Store), edit: %LOCALAPPDATA%\Packages\Claude_pzs8sxrjxfjjc\LocalCache\Roaming\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "lastfm-lyrics": {
      "command": "python",
      "args": ["C:/absolute/path/to/server.py"]
    }
  }
}

Fully quit and reopen Claude Desktop. The tools will appear automatically.

Usage

Play a song in Spotify, then ask Claude:

• "What am I listening to?"
• "Analyze what I'm listening to"
• "What's the mood of this song?"
• "What themes does this song explore?"
• "Tell me about the artist I'm listening to"
• "Get the lyrics for Blinding Lights by The Weeknd"

Notes

• Spotify free tier works — no Premium required
• There is a ~10–30 second delay between when a track starts and when Last.fm reports it
• Claude can analyze lyrics but will not reproduce them verbatim (copyright policy)
