“Use “domain-lookup”: Look up normalized RDAP registration data (registrar, status, dates, nameservers, contacts) for a domain name.”

“Use “bulk-domain-lookup”: Look up normalized RDAP registration data for several domain names in one pooled call. Requires a Pro or Business plan; every domain in the.”

“Use “ip-lookup”: Look up normalized RDAP allocation data (network range, holder, country, status) for an IP address or CIDR block.”

“Use “asn-lookup”: Look up normalized RDAP data (holder, country, status, registration dates) for an autonomous system number.”

Security check

How secure is the RDAP API MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how RDAP API holds up.

✓ Verified directory serverRDAP API · rdapapi.io

Official endpoint

Operated by RDAP API (rdapapi.io) 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 RDAP API adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

FAQ

Questions, answered

Is there an official RDAP API MCP server?

Yes — RDAP API operates its own remote MCP server at rdapapi.io. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.

How do I connect RDAP API to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick RDAP API in the directory. No account or sign-in is needed. From then on, RDAP API's tools are available in every client you've connected to gate.

Do I need to host anything?

No. RDAP API runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.

Is the RDAP API MCP server safe to connect?

It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
