MCP Domain Deliverability Checker runs on your own machine — the client starts it, so there is no endpoint to ping. 56 installs a week from npm. Last commit 8 Sep 2026.
Audit a domain email deliverability via Apify: SPF, DKIM, DMARC, MX, blacklist, catch-all, age.
Today is the operative word: we check MCP Domain Deliverability Checker every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
