MCP tool

check_srv

Map a domain's DNS-visible service footprint by probing 19 common SRV record prefixes (email, calendar, messaging, directory, web) in parallel.

The check_srv tool is provided by BlackVeil DNS & Email Security Scanner. Install that server in your AI client and the assistant can call it directly.

Servers exposing check_srv
