Look Up DNS Records
Query DNS records for any domain to inspect A, AAAA, MX, CNAME, TXT, and NS configurations.
Verify SPF and DKIM Records
Check that email authentication records are correctly configured to prevent spoofing and improve deliverability.
Quick answer: Use the DNS Domain tool through ToolRouter to verify spf and dkim records directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolSPF, DKIM, and DMARC records tell receiving mail servers how to verify that email claiming to be from your domain is legitimate. Misconfigured records mean your legitimate emails land in spam, or worse, anyone can send email pretending to be you.
The lookup_dns skill retrieves your TXT records so you can verify SPF, DKIM, and DMARC are set up correctly. Check that your SPF record includes all your sending services, that DKIM selectors resolve properly, and that DMARC policies are in place.

Claude turns DNS investigation into a deep, conversational security review where each finding leads naturally to the next check. Ask Claude to look up your records, chain that into an SSL verification, cross-reference with email authentication settings, and explain the security implications of every configuration detail it finds. Its analytical reasoning makes it ideal for thorough domain audits where understanding the "why" behind each record matters as much as seeing the data.
