Setup

Prerequisites

• Node.js v16+
• A Spotify Premium account
• A registered Spotify Developer application

Installation

git clone https://github.com/marcelmarais/spotify-mcp-server.git
cd spotify-mcp-server
npm install
npm run build

Creating a Spotify Developer Application

1. Go to the Spotify Developer Dashboard
2. Log in with your Spotify account
3. Click the "Create an App" button
4. Fill in the app name and description
5. Accept the Terms of Service and click "Create"
6. In your new app's dashboard, you'll see your Client ID
7. Click "Show Client Secret" to reveal your Client Secret
8. Click "Edit Settings" and add a Redirect URI (e.g., http://localhost:8888/callback)
9. Save your changes

Spotify API Configuration

Create a spotify-config.json file in the project root (you can copy and modify the provided example):

# Copy the example config file
cp spotify-config.example.json spotify-config.json

Then edit the file with your credentials:

{
  "clientId": "your-client-id",
  "clientSecret": "your-client-secret",
  "redirectUri": "http://localhost:8888/callback"
}

Authentication Process

The Spotify API uses OAuth 2.0 for authentication. Follow these steps to authenticate your application:

1. Run the authentication script:

npm run auth

2. The script will generate an authorization URL. Open this URL in your web browser.

3. You'll be prompted to log in to Spotify and authorize your application.

4. After authorization, Spotify will redirect you to your specified redirect URI with a code parameter in the URL.

5. The authentication script will automatically exchange this code for access and refresh tokens.

6. These tokens will be saved to your spotify-config.json file, which will now look something like:

{
  "clientId": "your-client-id",
  "clientSecret": "your-client-secret",
  "redirectUri": "http://localhost:8888/callback",
  "accessToken": "BQAi9Pn...kKQ",
  "refreshToken": "AQDQcj...7w",
  "expiresAt": 1677889354671
}

7. The server will automatically refresh the access token when needed, using the refresh token.

Integrating with Claude Desktop and Cursor

To use your MCP server with Claude Desktop, add it to your Claude configuration:

{
  "mcpServers": {
    "spotify": {
      "command": "node",
      "args": ["spotify-mcp-server/build/index.js"]
    }
  }
}

For Cursor, go to the MCP tab in Cursor Settings (command + shift + J). Add a server with this command:

node path/to/spotify-mcp-server/build/index.js
