Live DNS, TLS, HTTP and SEO checks for any host: cert expiry, headers, redirects.
Maintain this server? Claim it
Call this server's tools from your browser. Nothing to install.
Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.
Tool list from our last check. Connect live to refresh it.
Resolve DNS records (A/AAAA/MX/TXT/NS/CNAME/SOA) for a domain, queried live against 1.1.1.1. Use when you need to verify a domain resolves, check mail routing, or inspect TXT/SPF records.
Domain name, e.g. example.com
This tool isn't marked read-only, so it may change something on the server or in an account you connected.

}We read every tool's name, description and inputs the way the model will, looking for instructions hidden from you. A clean result means no warning signs, not a guarantee. Scanned Nov 1, 2026.
No readOnlyHint / destructiveHint annotations, so clients can't tell a read from a write without asking.
Fix: Add annotations to each tool, e.g. { readOnlyHint: true } for tools that only read.
