Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (9)

`check_bimi`read-only	Check the domain BIMI record at default._bimi: the SVG logo URL, the VMC/CMC certificate, and the DMARC enforcement BIMI needs.
`check_blacklist`read-only	Check whether the domain and its mail server IPs are listed on the Spamhaus (ZEN, DBL, ZRD, AuthBL), SpamCop, GBUdb and PSBL blocklists.
`check_dkim`read-only	Check DKIM signing keys for a domain. Without a selector, common provider selectors are probed. Pass an explicit selector to look up that exact key at selector._domainkey.
`check_dmarc`read-only	Check the domain DMARC policy at _dmarc: presence, policy strength (none/quarantine/reject), and reporting.
`check_dnssec`read-only	Check DNSSEC validation and DNS health: delegation, nameserver count, SOA, and reverse DNS of the mail servers.
`check_domain`read-only	Run the full email and DNS deliverability check for a domain: MX, SPF, DKIM, DMARC, DNS health, provider detection, and blacklists. Returns a letter grade (A+ to F, where specific weaknesses cap the grade), a 0 to 100 score, and every individual check with its RFC reference. Set include_smtp to also run a live SMTP probe of the mail servers: the probe is non-blocking, so when smtp_status is "pending" or "running" call this tool again (poll_after_seconds hints how long to wait) until smtp_status is "complete" and the SMTP checks appear in checks.
`check_mta_sts`read-only	Check the domain MTA-STS policy (_mta-sts TXT and the HTTPS policy file, mode and MX coverage) and its TLS-RPT reporting record.
`check_mx`read-only	Check the MX records of a domain: presence, hostnames, resolution, null-MX, and common misconfigurations.
`check_spf`read-only	Check the domain SPF policy: presence, syntax, the all qualifier, and the 10-lookup limit.

Schemas: list_tools.
