What the code does

We read the source, 2 d ago · tools taken from the live server · rules 995398eba69f

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

Nothing serious here today

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

Crypto Link Check — questions

Answers built from our own checks of this server.

What can Crypto Link Check do?
It exposes 2 tools, read directly from the server on our last check. Among them: check_crypto_link, full_report_info. 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 Crypto Link Check working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 93 ms. The bar chart above shows every period we have measured.
How do I connect Crypto Link Check?
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 Crypto Link Check need an API key?
No. Crypto Link Check completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Crypto Link Check?
It answers our handshake in 93 ms on average, which is faster than 93% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Crypto Link Check open source?
The code is open source: it is published under the MIT licence, written in HTML and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at crypto-link-check.nextill-pos.workers.dev, which runs on its operator's own terms.
