# How to Audit DNS Security 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: "Audit the DNS security for example.com using dns-domain -- check for misconfigurations and vulnerabilities"
3. Claude checks DNS records and SSL certificates, flagging issues
4. Address any security findings Claude identifies

## Example Prompt

```
Run a DNS security audit on example.com. Check for missing SPF records, dangling CNAMEs, SSL issues, and any other security concerns.
```

## Tips

- Ask Claude to prioritize findings by severity
- Run audits regularly as part of your security review process
- Check subdomains too -- they often have stale or insecure configurations
