Spotify MCP Server

This project implements a Model Context Protocol (MCP) server that allows you to control Spotify playback using natural language through an MCP client, such as Cursor or Claude for Desktop (macOS and Windows only).

Features

This server exposes the following tools:

• play: Play a track, album, or playlist, or resume playback.
• pause: Pause playback.
• next: Skip to the next track.
• previous: Skip to the previous track.
• get_current_track: Get information about the currently playing track.
• search: Search for tracks, albums, artists, or playlists.

Prerequisites

• Bun (version 1.0.0 or later)
• A Spotify Premium account.
• A Spotify Developer application:
  • Create one at the Spotify Developer Dashboard.
  • Obtain your Client ID and Client Secret.
  • Add http://localhost:8888/callback to the Redirect URIs in your app's settings.
• An MCP client (e.g., Cursor or Claude for Desktop).

Installation and Setup

1. Clone the repository:

   bash git clone https://github.com/obre10off/spotify-mcp.git cd spotify-mcp

2. Install dependencies:

   bash bun install

3. Create a .env file:

   Create a file named .env in the root of the project directory. Add the following, replacing the placeholders with your actual Spotify credentials:

   ``` SPOTIFY_CLIENT_ID=your_spotify_client_id SPOTIFY_CLIENT_SECRET=your_spotify_client_secret SPOTIFY_REDIRECT_URI=http://localhost:8888/callback

   These will be filled in after running the auth script:

   SPOTIFY_ACCESS_TOKEN= SPOTIFY_REFRESH_TOKEN= ```

4. Run the authorization script:

   This script will open your browser, prompt you to log in to Spotify and grant permissions, and then retrieve your initial access and refresh tokens.

   bash bun run auth

   The script will print the SPOTIFY_ACCESS_TOKEN and SPOTIFY_REFRESH_TOKEN to the console. Copy these values into your .env file.

5. Configure your MCP client:

   • Cursor:

     • Open Cursor's settings (Cmd+, or Ctrl+,).
     • Search for "Model Context Protocol".
     • Click "Edit in settings.json".

     • Add the following to the mcp.servers array (replace /absolute/path/to/your/spotify-mcp with the absolute path to your spotify-mcp directory):

       json { "mcp.servers": [ { "spotify": { "command": "bun", "args": ["/absolute/path/to/your/spotify-mcp/src/index.ts"], "env": { "SPOTIFY_CLIENT_ID": "your_spotify_client_id", "SPOTIFY_CLIENT_SECRET": "your_spotify_client_secret", "SPOTIFY_REDIRECT_URI": "http://localhost:8888/callback", "SPOTIFY_ACCESS_TOKEN": "your_spotify_access_token", "SPOTIFY_REFRESH_TOKEN": "your_spotify_refresh_token" } } } ] } It is recommended to use a .env file and only put the environment variables related to Spotify there, instead of adding the values to the settings.json file.

   • Claude for Desktop (macOS/Windows):

     • Open the Claude for Desktop configuration file:
       • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
       • Windows: %APPDATA%\Claude\claude_desktop_config.json
     • Add the following to the mcpServers object (replace /absolute/path/to/your/spotify-mcp with the absolute path to your spotify-mcp directory): json { "mcpServers": { "spotify": { "command": "bun", "args": ["/absolute/path/to/your/spotify-mcp/src/index.ts"] } } } It is recommended to use a .env file and only put the environment variables related to Spotify there, instead of adding the values to the claude_desktop_config.json file.

   • Important: Always use absolute paths in your client configuration.

6. Restart your MCP Client

Make sure to restart your MCP client (Cursor/Claude) to apply the settings.

Running the Server

```bash bun run start

This command starts the server with automatic reloading on file changes (thanks to Bun's --watch flag). Keep this terminal window open while you're using the server.

Usage

Once the server is running and your MCP client is configured, you can start using natural language commands to control Spotify. Examples:

"Play Bohemian Rhapsody"

"Pause the music"

"What song is playing?"

"Search for Taylor Swift albums"

"Next track"

"Play spotify:track:4uLU6hMCjMI75M1A2tKUQC"
