Imslp MCP server

mcp-imslp

IMSLP, the International Music Score Library Project, is also called the Petrucci Music Library. It is a free library of classical music run by volunteers, holding the sheet music, the parts, the arrangements and the recordings of works whose copyright has lapsed, together with what its pages say about each composer. It reviews the copyright of every score for Canada, the United States and the European Union separately, and publishes its pages under CC BY-SA 4.0.

This server connects a chat client to that library. You can search the works and the people it catalogues, read a work with its opus number, its key, its instrumentation and the year it was written, page through the editions a work holds with their publishers, editors and copyright terms, read what the library says about a composer, and browse a genre, a key or an instrumentation. It reads the library and links to it, and it needs no API key and no account.

Claude Desktop, Cursor, and any client using the standard config format

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

Node 24 or later is required, and no environment variable has to be set.

With Docker

{
  "mcpServers": {
    "imslp": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "ghcr.io/smeet666/mcp-imslp:1.0.1"]
    }
  }
}

-i keeps stdin open, which is where the protocol travels, and -t is left out because a TTY rewrites the stream. The container needs outbound HTTPS to imslp.org, and nothing else: no volume, no port, no credential.
