A side-by-side look at the Nslookup and SiteVitals MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Nslookup for monitoring work as a local process; choose SiteVitals for monitoring over a hosted endpoint. You can also run both side by side in one mcpServers block.
dns_lookup, dns_record, dns_propagation.list_sites, get_site_health, get_site_uptime.Rows where the two servers differ are marked.
