This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

MCP Imslp — questions

Answers built from our own checks of this server.

Why is there no uptime for MCP Imslp?
MCP Imslp runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package mcp-imslp was installed 47 times last week.
How do I connect MCP Imslp?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls mcp-imslp straight from npm; nothing to host, nothing to sign up for.
How many people use MCP Imslp?
The npm package mcp-imslp was installed 47 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is MCP Imslp open source?
Yes — it is published under the MIT licence, written in TypeScript, 0 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
