Bandcamp crate digging

bandcamp-mcp

Dig through Bandcamp by talking to Claude: chase a label's roster, see what is new under a tag, pull up an album's tracklist and price, and find who actually made track 7 on that compilation. bandcamp-mcp is a local MCP server — the way an AI assistant reaches tools on your machine — so any MCP client can use it: Claude Desktop, Claude Code, Cursor, VS Code. No account, no API key, nothing to configure.

Status: experimental. Pre-1.0 and actively developed: a minor version may change behaviour or break compatibility, a patch never does. Only the latest release is supported.

Not affiliated with, endorsed by, or sponsored by Bandcamp.

What you can ask

• "What's in the Sacred Bones catalogue, and who is each release by?"
• "Find the album *Cathedral* by John Carpenter and read me the tracklist with track lengths."
• "Show me ten new releases under the tag drum-bass, then open each one and tell me its label and release date."
• "Is that compilation various-artists? Tell me who made each track."
• "How much is this album, and is it name-your-price?"
• "Find that Bandcamp link a friend sent me and tell me what else the artist has released."

Answers come from Bandcamp's own public pages, fetched live — one request per tool call the assistant makes. The server reads; it never buys, downloads or touches an account, and it has no field in which a stream or download link could reach you.

Install

npx is the whole install: your MCP client starts the server on demand and picks up fixes the next time it launches.

Claude Code:

claude mcp add bandcamp -- npx -y bandcamp-mcp

Claude Desktop (Settings → Developer → Edit Config), or any MCP client that starts a stdio server from a command:

{

"mcpServers": { "bandcamp": { "command": "npx", "args": ["-y", "bandcamp-mcp"] } } }

Cursor: install in Cursor, or add the same JSON block to ~/.cursor/mcp.json.

VS Code (Copilot agent mode): install in VS Code, or run code --add-mcp '{"name":"bandcamp","command":"npx","args":["-y","bandcamp-mcp"]}'.

Claude Code plugin: this repository is also a plugin (.claude-plugin/plugin.json), so /plugin can install it once it is listed.

Requirements, and what is actually tested

Node.js 20 or newer (22 LTS recommended); Node 18 is end-of-life and a dependency of the MCP SDK requires 20. Every push runs the test suite on Node 20, 22 and 24, then packs the package, installs it into an empty project and starts it through an MCP handshake on Linux, macOS and Windows, on each of those Node versions. Nothing else is claimed: other platforms may well work, but no one has measured them.

Bandcamp itself has no versioned API. What the server reads is whatever bandcamp.com serves today, which is why a smoke test runs against the live site daily (badge above) and why a tool can start failing without warning — see How this works.

To pin a version, use bandcamp-mcp@ (e.g. npx -y bandcamp-mcp@0.1.0). An unpinned npx -y bandcamp-mcp picks up fixes the next time your client starts it; a pinned or globally installed copy does not (see Known limitations).

Windows

GUI MCP clients on Windows often can't start npx directly, because it is a .cmd script. Wrap it in cmd /c:

{

"mcpServers": { "bandcamp": { "command": "cmd", "args": ["/c", "npx", "-y", "bandcamp-mcp"] } } }

With Claude Code:

claude mcp add bandcamp -- cmd /c npx -y bandcamp-mcp

CI checks this command: on windows-latest, the package job installs the packed package into a project and runs cmd /c npx -y bandcamp-mcp there through an MCP handshake (initialize, then tools/list). There, npx finds the installed copy instead of downloading it, so the check covers how the server starts on Windows, not the download.

Troubleshooting: "server disconnected" / spawn npx ENOENT

GUI-launched MCP clients often start servers with a minimal PATH that leaves out nvm/volta shims, even when npx -y bandcamp-mcp works in your terminal. Install the package globally and point the client at absolute paths instead:

npm install -g bandcamp-mcp

which node # the "command" below (Windows: where node) echo "$(npm root -g)/bandcamp-mcp/dist/index.js" # the "args" entry below

{

"mcpServers": { "bandcamp": { "command": "/absolute/path/to/node", "args": ["/absolute/path/to/node_modules/bandcamp-mcp/dist/index.js"] } } }

On Windows, every backslash in the JSON paths must be doubled, e.g. C:\\Users\\you\\AppData\\Roaming\\npm\\node_modules\\bandcamp-mcp\\dist\\index.js. A global install doesn't update itself: run npm install -g bandcamp-mcp@latest to pick up a fix.

If your network blocks the npm registry

npx looks the package up on registry.npmjs.org whenever your client starts the server. If the registry is blocked, or only sometimes reachable, run npm install -g bandcamp-mcp once while you have access and use the absolute-path config above, which starts without the registry.

How this works, and why it can break

Bandcamp has no public catalog API, so every tool call makes live requests to the same endpoints Bandcamp's own website uses:

• bandcamp_search: the JSON endpoint behind Bandcamp's search box (/api/bcsearch_public_api/1/autocomplete_elastic);
• bandcamp_browse_tag: the JSON endpoint behind bandcamp.com/discover (/api/discover/1/discover_web);
• bandcamp_get_album and bandcamp_get_track: the public release or track page, read mostly from its schema.org JSON-LD block, with tags from the page markup;
• bandcamp_get_artist: the artist's or label's /music page, read from its markup.

None of these is a published, versioned API. Bandcamp can change them at any time and without notice, and a tool then stops working until this project ships a fix. When that happens the tool says so ("Bandcamp's response format looks like it changed", or that it got a bot check instead of data) and links to the issues page. A daily smoke test (badge above) runs every tool's client code against live Bandcamp pages and reports failures to a tracking issue. The endpoint notes are in docs/bandcamp-endpoints.md.

• Metadata only. Releases are identified by slug, and the result schemas (src/client/types.ts) have no field for stream, download or purchase links, so the signed audio links in Bandcamp's pages can't pass through. (Free-text fields are the artists' own words, and may mention links.)
• No caching or republishing. Every tool call is fetched live. Nothing is stored; results go to your MCP client and nowhere else.
• No telemetry. Neither this package nor Venut Technologies collects anything; what the server reads, sends and stores is listed in PRIVACY.md. But every tool call is a request from your machine straight to Bandcamp, which sees your IP address, what you asked for and when. The requests also say where they come from, with the User-Agent Mozilla/5.0 (compatible; bandcamp-mcp/ ; +https://github.com/Venut-Technologies/bandcamp-mcp), so they don't look like a browser visit.
• Gentle by design. At most 3 requests in flight, at least 150 ms apart, a 7-second timeout, and one retry for a timeout, a transport-level failure (a reset or closed socket, a DNS or TLS error), 5xx or 429 (honoring a Retry-After of up to 5 s). Only bandcamp.com and *.bandcamp.com hosts are ever fetched: redirects are followed by hand (at most 3) and each target is checked against that list.

Bandcamp's robots.txt closes /api/ to crawlers, which covers the search endpoint, and explicitly allows the browse one. This server is not a crawler: it fetches one page per tool call you make, follows no links and stores nothing. That reading, the argument against it, and the commitment to change or drop a tool if Bandcamp objects are all recorded in CONTRIBUTING.md.

The repository (not the npm package) contains pages and API responses captured from Bandcamp as test fixtures, with the signed stream and download URLs redacted, the identities and free text replaced by invented ones, and each page cut down to the markup the parsers read.

Tools

Every slug is a Bandcamp identifier copied from an earlier result ( /album/ , /track/ , or a bare subdomain for an artist or label), never a display name. The tools take no URLs: a Bandcamp URL https:// .bandcamp.com/album/ becomes the slug /album/ , and the tool descriptions tell the model so. A result whose slug is null can't be looked up (see custom domains below).

Known limitations

• Single-maintainer, best-effort project, with no SLA. The daily smoke test is monitoring, not a support guarantee.
• Prompt injection. Names, titles, bios, desc
