Spotify MCP Server

A Model Context Protocol (MCP) server that provides Spotify integration with OAuth authorization flow based on the Model Context Protocol specification.

Files

• index.ts - MCP server setup and tool registration with StreamableHTTPServerTransport
• spotify.ts - Spotify API service with token management
• auth.ts - BetterAuth configuration with Drizzle adapter
• db/ - Database schema and connection using Drizzle ORMotocol (MCP) server that provides Spotify integration with OAuth authorization flow based on the Model Context Protocol specification.

Features

• OAuth Authorization Flow: Implements MCP's authorization specification with Spotify OAuth
• Streaming HTTP Transport: Uses MCP's StreamableHTTPServerTransport for efficient communication
• Automatic Token Refresh: Handles Spotify access token expiration and refresh automatically
• Simple Architecture: Clean separation between authentication, Spotify API calls, and MCP tools
• Comprehensive Spotify Tools: Multiple tools for controlling Spotify playback

Available Tools

• spotify.ts - Spotify API service with token management
• auth.ts - Better Auth configuration
• db/ - Database schema and connection

Token Management

The SpotifyService class automatically handles:

• Token expiry checking (with 5-minute buffer)
• Automatic token refresh using refresh tokens
• Database updates for new tokens
• Error handling for failed refreshes

Key Features

• Token Refresh: Automatically refreshes tokens before they expire
• Database Integration: Uses Drizzle ORM with PostgreSQL for token storage
• Error Handling: Graceful handling of API errors and token issues
• Session Management: Secure session handling with Better Auth

Setup

1. Set environment variables:

   SPOTIFY_CLIENT_ID=your_spotify_client_id
   SPOTIFY_CLIENT_SECRET=your_spotify_client_secret
   

2. Configure database connection in db/index.ts

3. Run database migrations:

   bun run drizzle-kit push
   

4. Start the server:

   bun run index.ts
   

Usage

1. Navigate to http://localhost:3000/sign-in to authenticate with Spotify
2. Use the MCP tools through your MCP client
3. The server automatically handles token refresh in the background

Technical Notes

• Uses BetterAuth with Drizzle adapter for OAuth flow with Spotify
• Implements the MCP Authorization specification for secure authentication
• Utilizes StreamableHTTPServerTransport for efficient communication
• Stores tokens securely in PostgreSQL database via Drizzle ORM
• Clean separation of concerns between authentication, API calls, and MCP tools
