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
