# How to Monitor DNS Changes with Claude

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.

## Setup

claude mcp add toolrouter -- npx -y toolrouter-mcp

## Steps

1. Connect ToolRouter: claude mcp add toolrouter -- npx -y toolrouter-mcp
2. Ask Claude: "Check the current DNS records and WHOIS data for example.com using dns-domain"
3. Claude returns the current state of records and registration details
4. Compare against your expected configuration and flag any discrepancies

## Example Prompt

```
Check the DNS records and WHOIS data for example.com. I want to verify nothing has changed since our last audit.
```

## Tips

- Keep a documented record of your expected DNS configuration for comparison
- Check WHOIS data to verify nameserver assignments have not changed
- Run checks after any security incident to confirm DNS integrity
