StableDomains — questions

Answers built from our own checks of this server.

What can StableDomains do?

It exposes 32 tools, read directly from the server on our last check. Among them: buy_with_balance, check_order, create_cart, create_order, dns_email_check, drop_radar and 26 more. 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 →

What is StableDomains mostly used for?

Its tools cluster around dns, order and domains. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is StableDomains working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 19 ms. The bar chart above shows every period we have measured.

The registry lists StableDomains 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 StableDomains?

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 StableDomains need an API key?

No. StableDomains completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 32 of them are readable on this page. This is what we observed, not what the docs claim.
