}Audit a domain's email deliverability and DNS health. Returns SPF, DKIM, and DMARC authentication with policy, MX records and mail provider, DNS blacklist status, catch-all detection, domain age, and a 0 to 100 health score as a flat, Clay-ready JSON row. Read-only; requires an APIFY_TOKEN and consumes Apify credits per call.
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.
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.
