What your AI can do with Front Sentinel
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “scan_domain”: Scores how well a dApp or website domain is protected against hijacking: registrar transfer/update locks, registry lock, DNSSEC, CAA, expiry.”
“Use “check_registry_lock”: Reads the domain's EPP status codes from RDAP and tells whether registry lock (serverUpdateProhibited + serverTransferProhibited) is on, par.”
“Use “check_sri”: Loads a public page and lists every script, stylesheet and preload it pulls in. For third-party files, checks whether an integrity= hash is.”
“Use “check_seal_dns_registrar”: Goes through the 16 controls of the SEAL Security Frameworks certification for DNS & Registrar and marks what public data shows for each: ok.”
How secure is the Front Sentinel MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Front Sentinel holds up.
Official endpoint
Operated by Front Sentinel (frontsentinel.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 Front Sentinel adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps
Connect your gate
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Pick Front Sentinel
Choose Front Sentinel in the gate directory. No sign-in needed.

Front Sentinel's tools are live in every AI client you've connected — with rules and logging built in.

The Front Sentinel MCP server at a glance
https://frontsentinel.com/mcpQuestions, answered
Is there an official Front Sentinel MCP server?
Yes — Front Sentinel operates its own remote MCP server at frontsentinel.com. 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 Front Sentinel to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Front Sentinel in the directory. No account or sign-in is needed. From then on, Front Sentinel's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Front Sentinel runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Front Sentinel 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.
Is it free?
Yes — you can get started with gate for free and connect Front Sentinel in minutes. No credit card required.
