email_verify

Check whether an email address looks real and deliverable before sign-up, outreach or invoicing. For up to 25 addresses: RFC syntax, MX (or A fallback) records, disposable domain (CC0 list, ~10k domains), role account, free-mail provider, the domain's SPF and DMARC, and a verdict (valid, risky, invalid). It never contacts mail servers, so it cannot confirm that a mailbox exists. Use when you need a quick check with no side effects. $0.0015 per call, USDC on Base (x402).

Email Address Check (syntax, MX, disposable, SPF/DMARC) — questions

Answers built from our own checks of this server.

What can Email Address Check (syntax, MX, disposable, SPF/DMARC) do?

It exposes 1 tools, read directly from the server on our last check. Among them: email_verify. 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 Email Address Check (syntax, MX, disposable, SPF/DMARC) 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 190 ms. The bar chart above shows every period we have measured.

Is Email Address Check (syntax, MX, disposable, SPF/DMARC) still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

The registry lists Email Address Check (syntax, MX, disposable, SPF/DMARC) 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 Email Address Check (syntax, MX, disposable, SPF/DMARC)?

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 Email Address Check (syntax, MX, disposable, SPF/DMARC) need an API key?

No. Email Address Check (syntax, MX, disposable, SPF/DMARC) 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.
