Nothing serious here today

Today is the operative word: we check LibraryAPI every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start: LIBRARYAPI_KEY (API key from https://libraryapi.dev (free tier: 500 requests/month)). The author declared them in the registry entry; get the values from the project itself.

LibraryAPI — questions

Answers built from our own checks of this server.

Why is there no uptime for LibraryAPI?

LibraryAPI 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 pypi package libraryapi-mcp was installed 136 times last week.

How do I connect LibraryAPI?

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 libraryapi-mcp straight from pypi; nothing to host, nothing to sign up for.

How many people use LibraryAPI?

The pypi package libraryapi-mcp was installed 136 times in the last week. Week over week that is -20%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is LibraryAPI open source?

We cannot say either way: written in Python and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
