- check_domain
Runs fresh, bounded public SPF, DMARC, MX and optionally specified DKIM-selector DNS checks. Changes the public saved snapshot. Rate limited. DNS findings do not prove message authentication.
- get_saved_result
Reads the last saved, timestamped public snapshot without making any DNS queries. Results expire after 90 days.
Security scan
No findings
We scan names, descriptions and tool definitions for hidden instructions and other prompt-injection patterns.
