Frequently asked questions

1

What are the system requirements?

Node.js v18 or later, Docker (Docker Desktop on macOS/Windows, or Docker Engine on Linux), and an MCP-compatible client like Claude Desktop.

2

Can I analyze any domain without permission?

No. Only analyze domains you own or have explicit permission to test. Misuse may violate laws and DNS server policies.

3

What data does DNStwist MCP Server capture?

It collects DNS records (A, AAAA, MX, NS), HTTP banners, WHOIS info, and fuzzy hashes of web pages. Output can be JSON, CSV, or a simple list.

4

How do I troubleshoot Docker issues?

Verify Docker is installed and running with `docker --version` and `docker ps`. On Linux ensure your user is in the docker group. Also confirm Docker has permission to run commands.

5

What are known limits or performance concerns?

DNS servers may rate-limit or block automated queries. Thread count (default 50) can be adjusted based on system capabilities and network latency. Large scans should be done responsibly to avoid impacting DNS infrastructure.
