Common questions about connecting and running DNS.
What DNS security checks does this server perform?
It validates DNSSEC signatures, retrieves email authentication records (SPF, DKIM, DMARC), and queries RDAP for domain registration and abuse contact data. Designed for SOC teams investigating compromised or malicious domains.
How do I install and run the DNS MCP server?
Pull and run the Docker image: `docker run docker.io/mclose/dns-mcp:1.3.4`. It communicates via stdio, so connect it to your MCP client (Claude, etc.) using the stdio transport.
Does this server require API keys or authentication?
The registry metadata does not specify required environment variables or API keys. Check the Docker image documentation or run it to see if any configuration is needed for RDAP or DNS queries.
Can I use this for real-time threat investigation?
Yes—it's built specifically for SOC investigations with real-time DNS and RDAP lookups. You can quickly validate DNSSEC, check email authentication, and retrieve abuse contacts during incident response.
What's the difference between this and a standard DNS lookup tool?
This server combines DNS security validation (DNSSEC), email authentication verification (SPF/DKIM/DMARC), and RDAP registration data in one interface. Standard tools typically only do basic DNS queries.
