KooLink URL Shortener missed 2 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

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 91 of 92 checks got a reply (98.9%), average response time 1334 ms. The bar chart above shows every period we have measured.

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 in the form 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.

How fast is KooLink URL Shortener?

It answers our handshake in 1334 ms on average, which is faster than 2% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is KooLink URL Shortener open source?

The code is open source: it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.kool.ink, which runs on its operator's own terms.
