✓ Verified directory serverWeb3 DNS (CNSLookup) · cnslookup.com

Official endpoint

Operated by Web3 DNS (CNSLookup) (cnslookup.com) at its documented MCP endpoint — not a third-party mirror or community re-host.

No sign-in needed

This server only exposes public data — no account and no credentials are involved when you connect.

Scanned before it goes live

gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.

Watched for drift

If Web3 DNS (CNSLookup) adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
