Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “get_my_ip”: Return the public IP address (and ISP, ASN, location, timezone) of the caller as seen by FernTool. Note: for remote agents this is the IP of.”
“Use “lookup_ip”: Validate an IPv4/IPv6 address and return its version, scope (public/private/loopback/...), country, ASN and network owner (DB-IP Lite + IPto.”
“Use “validate_ip”: Check whether a string is a valid IPv4 or IPv6 address and classify it.”
“Use “batch_lookup_ip”: Look up 1-100 IPv4/IPv6 addresses at once. Each result has version, scope, country, timezone, ASN, network owner and flags (is_tor, is_datac.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how FernTool IP Lookup holds up.
Operated by FernTool IP Lookup (ferntool.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If FernTool IP Lookup adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose FernTool IP Lookup in the gate directory. No sign-in needed.
FernTool IP Lookup's tools are live in every AI client you've connected — with rules and logging built in.
