🎵 Discogs MCP Server

A powerful Model Context Protocol (MCP) server that enables AI assistants to interact with your personal Discogs music collection. Built on Cloudflare Workers using the official Cloudflare Agents SDK and @modelcontextprotocol/sdk.

✨ Features

• 🔐 Secure OAuth Authentication: Connect your Discogs account safely
• 🧠 Intelligent Mood Mapping: Translate emotions into music ("mellow", "energetic", "Sunday evening vibes")
• 🔍 Advanced Search Intelligence: Multi-strategy search with OR logic and relevance scoring
• 📊 Collection Analytics: Comprehensive statistics and insights about your music
• 🎯 Context-Aware Recommendations: Smart suggestions based on mood, genre, and similarity
• ⚡ Edge Computing: Global low-latency responses via Cloudflare Workers
• 🗂️ Smart Caching: Intelligent KV-based caching for optimal performance

⚠️ This Is Not a Shared Service

discogs-mcp.com is the maintainer's private instance. It's locked to a single Discogs account and will return a 403 for anyone else.

Why? The Discogs API rate limit (60 requests per minute, per registered app) is too tight to share across users. One active collection query from a single user can saturate it. Rather than run a broken multi-tenant service, each user deploys their own Worker with their own Discogs API credentials.

The good news: deploying your own copy is straightforward, runs on the Cloudflare Workers free tier, and takes about 10 minutes. See Self-Hosting below.

🚀 Self-Hosting

Prerequisites

• Node.js 18+
• Cloudflare account (free tier is fine)
• Discogs account with a registered developer app (you'll need a Consumer Key and Consumer Secret)

1. Clone and install

git clone https://github.com/rianvdm/discogs-mcp.git
cd discogs-mcp
npm install

2. Create KV namespaces

wrangler kv namespace create MCP_SESSIONS --env production
wrangler kv namespace create MCP_LOGS --env production
wrangler kv namespace create OAUTH_KV --env production

Copy the returned IDs into wrangler.toml under [env.production].

3. Set your Discogs credentials

wrangler secret put DISCOGS_CONSUMER_KEY --env production
wrangler secret put DISCOGS_CONSUMER_SECRET --env production
wrangler secret put JWT_SECRET --env production   # any random string

4. (Optional but recommended) Lock your instance to your own Discogs user

By default, anyone with a Discogs account who discovers your Worker URL can authenticate and consume your rate-limit budget. To restrict it to just you — or to a small group of trusted users — set ALLOWED_DISCOGS_USER_ID in wrangler.toml under [env.production.vars]:

[env.production.vars]
# Single user
ALLOWED_DISCOGS_USER_ID = "123456"

# Or a comma-separated list for multiple users
ALLOWED_DISCOGS_USER_ID = "123456,789012,345678"

You can find your numeric ID by visiting https://api.discogs.com/users/<your-username> and looking at the id field. Leave the value empty to run an open instance.

5. Deploy

npm run deploy:prod

Your Worker URL will be something like https://discogs-mcp.<your-subdomain>.workers.dev. The MCP endpoint is /mcp.

6. Connect your MCP client

Replace https://your-worker.workers.dev below with your own URL.

🔐 Authentication

This server uses MCP OAuth 2.1 with Discogs as the identity provider. When you connect for the first time:

1. Your MCP client automatically opens a browser window
2. Authorize the application on Discogs
3. You're redirected back and authenticated — no copy-pasting required
4. Your session persists for 7 days

📚 MCP Resources

Access Discogs data via standardized MCP resource URIs:

discogs://collection             # Complete collection (JSON)
discogs://release/{id}           # Specific release details
discogs://search?q={query}       # Search results

🏗️ Local Development

# Set dev secrets (same Discogs app is fine for dev)
wrangler secret put DISCOGS_CONSUMER_KEY
wrangler secret put DISCOGS_CONSUMER_SECRET
wrangler secret put JWT_SECRET

# Run the Worker locally
npm run dev

# Test with MCP Inspector
npx @modelcontextprotocol/inspector http://localhost:8787/mcp

The default [vars] block in wrangler.toml leaves ALLOWED_DISCOGS_USER_ID empty, so local dev is open to any Discogs account — convenient for testing.

🧪 Testing

npm test              # Run all tests
npm test -- --watch  # Run tests in watch mode
