KooLink URL Shortener — questions

Answers built from our own checks of this server.

What can KooLink URL Shortener do?

It exposes 3 tools, read directly from the server on our last check. Among them: link_stats, list_links, shorten_url. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is KooLink URL Shortener working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 367 ms. The bar chart above shows every period we have measured.

The registry lists KooLink URL Shortener as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect KooLink URL Shortener?

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 is a remote server, so there is nothing to install — the client connects to the address.

Does KooLink URL Shortener need an API key?

No. KooLink URL Shortener completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

Is KooLink URL Shortener open source?

Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
