Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mcp-imslp find piano scores for Debussy's Clair de Lune"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
An MCP server for IMSLP, the Petrucci Music Library: works, scores and recordings of classical music, catalogued by the volunteers who run it. No API key and no account are needed.
The library publishes its pages under CC BY-SA 4.0, so anything shown from this server credits IMSLP and links the page it came from.
Reads go through the MediaWiki API at /api.php and through the listing
endpoint IMSLP documents on its own IMSLP:API page. The robots.txt of the site
disallows /index.php, /images/, /imglnks/, /wiki/File:, /works and
/library/, and this server builds no address under any of them: it downloads
no score file, and hands back the link to the work page instead.
IMSLP publishes Crawl-delay: 2, so requests run one at a time with at least
two seconds between them. That floor holds however the server is configured.

A score on IMSLP carries a status per jurisdiction, and the library reviews
Canada, the United States and the European Union. A file can read
Public Domain - Non-PD US: free in one place and protected in another. This
server reports the status as published, per jurisdiction, and never flattens it
into "public domain".

Un serveur MCP pour IMSLP, la Petrucci Music Library : œuvres, partitions et enregistrements de musique classique, catalogués par les bénévoles qui la tiennent. Aucune clé d'API, aucun compte.
La bibliothèque publie ses pages sous CC BY-SA 4.0, donc tout ce que ce serveur rend attribue à IMSLP et renvoie vers la page d'origine.
Les lectures passent par l'API MediaWiki /api.php et par le point d'entrée
qu'IMSLP documente sur sa page IMSLP:API. Le robots.txt du site interdit
/index.php, /images/, /imglnks/, /wiki/File:, /works et /library/, et
ce serveur ne construit aucune adresse sous ces chemins : il ne télécharge
aucun fichier de partition et rend le lien de la page de l'œuvre.
IMSLP publie Crawl-delay: 2, donc les requêtes partent une à une, avec au
moins deux secondes entre elles, quelle que soit la configuration.
Une partition porte sur IMSLP un statut par juridiction, et la bibliothèque
vérifie le Canada, les États-Unis et l'Union européenne. Un fichier peut être
Public Domain - Non-PD US : libre ici et protégé ailleurs. Ce serveur rend le
statut tel qu'il est publié, juridiction par juridiction.
