MCP Domain Auditor — questions

Answers built from our own checks of this server.

What can MCP Domain Auditor do?

It exposes 1 tools, read directly from the server on our last check. Among them: audit_domain. 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 MCP Domain Auditor 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 57 ms. The bar chart above shows every period we have measured.

Did MCP Domain Auditor ever remove tools?

Yes. dns_lookup, email_hygiene, security_headers are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect MCP Domain Auditor?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does MCP Domain Auditor need an API key?

No. MCP Domain Auditor completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is MCP Domain Auditor?

It answers our handshake in 57 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 MCP Domain Auditor open source?

We cannot say either way: written in TypeScript and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
