SureCheck MCP runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 15 Oct 2026.
Local stdio phone metadata and email syntax/DNS checks. Not live carrier or mailbox verification.
Today is the operative word: we check SureCheck MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
Domain email and webmail: set up domains, mailboxes and aliases, and check DNS verification.

Verify email addresses in real time and find business email addresses with live mailbox checks.
Check whether an email address can receive mail, one address or a list, without sending to it.
Finds, filters, and verifies local-business leads; every email carries a verification receipt.
Phone carrier, email domain, IP network and DNS checks using your LookupLab account.
