Look Up DNS Records
Query DNS records for any domain to inspect A, AAAA, MX, CNAME, TXT, and NS configurations.
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.
ToolDNS DomainSPF, 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.
ToolRouterhttps://api.toolrouter.com/mcpClaude 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.
Once connected (see setup above), use the DNS Domain tool — the same steps work with Claude, ChatGPT, Microsoft Copilot, OpenClaw, and any MCP client:
Check that email authentication records are correctly configured to prevent spoofing and improve deliverability. Connect the DNS Domain tool to Claude, ChatGPT, Microsoft Copilot, and OpenClaw through ToolRouter, then ask the assistant in plain language. For example: Ask Claude: "Check the SPF, DKIM, and DMARC records for example.com using dns-domain" Claude retrieves the TXT records and analyzes your email authentication setup
Claude, ChatGPT, Microsoft Copilot, and OpenClaw can all verify spf and dkim records using the DNS Domain tool through ToolRouter, with no API keys or coding required.
Look up DNS records, check WHOIS data, and verify SSL certificates. Monitor domain infrastructure and diagnose configuration issues.
