setlist-mcp

An MCP server that lets Claude find setlist.fm setlists for gigs you've been to.

Ask "I saw The Cure in Wellington in August 1992 — what did they play?" and Claude resolves the artist, searches setlist.fm, and reads back the songs in order.

Features

• find_setlists — search by artist, city and date. Returns a compact list of matching gigs with their setlist IDs, venues and song counts.
• get_setlist — fetch one setlist in full: every song in order, grouped into sets and encores, with cover and guest-appearance notes.
• Forgiving about dates. Searching covers the year around the date you give and ranks results by how close they are, so a misremembered day still finds the gig.
• Forgiving about artist names. Names resolve through MusicBrainz, so minor misspellings usually still work. Ambiguous names come back with alternatives.
• Careful with rate limits. Requests are serialised and spaced out, 429s are retried with backoff, and responses are cached. Searches take a few seconds by design.

Installation

git clone git@github.com:adrianparker/setlist-mcp.git
cd setlist-mcp
npm install
cp .env.example .env

Then edit .env and set SETLISTFM_API_KEY. Request a key at setlist.fm's API settings — it's free, and requires a setlist.fm account.

Setting MUSICBRAINZ_CONTACT to your email address is good manners: MusicBrainz asks that clients identify a contact in their User-Agent, and throttles anonymous-looking clients harder.

Registering with Claude Code

claude mcp add setlist-mcp --scope user -- node /full/path/to/setlist-mcp/src/index.js

Or add it to a project's .mcp.json:

{
  "mcpServers": {
    "setlist-mcp": {
      "command": "node",
      "args": ["/full/path/to/setlist-mcp/src/index.js"]
    }
  }
}

No secrets go in the client config — the server reads .env from its own directory, so it works whatever directory the client launches it from.

Restart Claude Code, then check it connected with /mcp.

Usage

Once registered, just ask in plain English:

I saw Villainy in Tauranga in March 2026, what was the setlist?

Claude will call find_setlists, pick the matching gig, then call get_setlist.

To check the server directly without a client:

npx @modelcontextprotocol/inspector node src/index.js

Configuration

Variable	Default	Purpose
SETLISTFM_API_KEY	—	Required. Your setlist.fm API key.
MUSICBRAINZ_CONTACT	repo URL	Contact detail sent to MusicBrainz in the User-Agent.
NODE_ENV	app	Which src/config/<env>.json the logger loads.
SETLISTFM_MIN_INTERVAL_MS	1100	Minimum gap between setlist.fm requests.
SETLISTFM_DAILY_LIMIT	1300	Per-process request budget for setlist.fm.
MUSICBRAINZ_MIN_INTERVAL_MS	1100	Minimum gap between MusicBrainz requests.
HTTP_TIMEOUT_MS	10000	Per-request timeout.

Rate limiting

setlist.fm doesn't publish its rate limits. Community reports put the standard tier at roughly 2 requests per second and 1440 per day, so the defaults here — one request every 1.1 seconds — sit comfortably inside the slower end of that. Requests are serialised through a queue, so concurrent tool calls wait their turn rather than bursting. A 429 backs off the whole queue, honouring Retry-After when the server sends one.

The daily limit is not a real daily quota. It's held in memory, so it resets whenever the MCP client restarts the server. Treat it as a circuit breaker against a runaway loop, not as compliance. The minimum interval is what actually protects your key: at 1.1s per request, reaching 1440 requests would take 26 minutes of continuous querying.

Responses are cached in memory — artists for 24 hours, searches for 1 hour, setlist detail for 6 hours — so repeated questions about the same gig cost nothing.

Development

Run tests

npm test
npm run test:watch

No test touches the real APIs: test/setup.js installs a global.fetch that throws, and tests stub it explicitly.

Coverage

npm run coverage

Lint

npm run lint

A note on setlist.fm

The setlist.fm API is free for non-commercial use only — see their API terms. Both tools return the setlist.fm URL for every result so it can be linked back to.

Setlist data is contributed by setlist.fm's users. Gigs may be missing, incomplete, or have the wrong date.
