概要

What is Domain Deliverability Checker?

A server that performs DNS-based deliverability checks on any sending domain before contacting, enriching, or qualifying it. It validates SPF, DKIM, and DMARC records, checks MX record presence, queries 10 major DNS blacklists, and estimates domain age via RDAP/SOA, producing a weighted 0–100 composite score. It is built for Clay enrichment tables, GTM workflows, and outbound pre-qualification, with a free‑tier cap of 50 checks per month.

How to use Domain Deliverability Checker?

Install via npx: npx @mambalabsdev/mcp-domain-deliverability-checker. Invoke the tool check_domain_deliverability with a domain argument. No further configuration steps are described in the README.
