Unmeasured means there is not enough evidence to decide. How these checks work
Start using Zovo DNS Checker
Choose your client, copy the configuration, then enable the server in your client’s MCP settings.
Run this command in your terminal, then restart Claude Code.
Claude Code
claude mcp add --transport http zovo-dns-checker https://dns-checker.zovo.one/mcpCapabilities
Use this when the user wants an email DNS check, a DMARC checker, an SPF record checker, a DKIM checker, or an MX lookup for a domain. Reads the live public DNS records through DNS-over-HTTPS and returns MX hosts, the SPF record with its DNS-lookup count against the limit of 10, the DMARC policy, reporting and alignment, DKIM keys for the selectors you give, and a pass/warn/fail findings list with a fix and a CSV report. Do not use for internal DNS server visibility, full deliverability tests, or reading or sending mail.
DiscoveredUse this when the user wants a dns lookup, an mx record check, or a txt record lookup for a domain. Reads live public DNS records through DNS-over-HTTPS and returns A, AAAA, MX, NS, TXT, CNAME, CAA, and SOA records with their TTLs, plus a CSV report. Do not use for internal DNS server visibility, reverse DNS of an IP address, or records outside the supported type list.
