Nothing serious here today

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

This endpoint answered with an authorization challenge. The server is running, but you need an API key from its owner to call it.

Unstoppable Domains — questions

Answers built from our own checks of this server.

Why is there no tool list for Unstoppable Domains?

The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.

Is Unstoppable Domains working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 253 ms. The bar chart above shows every period we have measured.

How do I connect Unstoppable Domains?

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. You will need your own key: it refuses anonymous clients.

Does Unstoppable Domains need an API key?

Yes. Every time we knock, Unstoppable Domains answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.

How fast is Unstoppable Domains?

It answers our handshake in 253 ms on average, which is faster than 56% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Unstoppable Domains open source?

The code is open source: it is published under the MIT licence, 3 stars on GitHub and 2 open issues. The licence covers the code in the repository, not the hosted service at api.unstoppabledomains.com, which runs on its operator's own terms.
