CustomDomain™ missed one check 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.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

CustomDomain™ — questions

Answers built from our own checks of this server.

Why is there no tool list for CustomDomain™?

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 CustomDomain™ 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 461 ms. The bar chart above shows every period we have measured.

How do I connect CustomDomain™?

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 sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to CustomDomain™?

No API key is involved. CustomDomain™ answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is CustomDomain™?

It answers our handshake in 461 ms on average, which is faster than 27% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is CustomDomain™ open source?

The code is open source: it is published under the MIT licence, 0 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at mcp.customdomain.ai, which runs on its operator's own terms.
