What your AI can do with Domain Check
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “check_domain”: Check whether anyone can spoof mail from a domain and whether its own mail will land: SPF, DMARC, MX and visible DKIM selectors, graded A-F,.”
“Use “list_services”: The paid catalogue: what each service covers, what it costs, and the exact URL where a customer orders. Include your referral code in the or.”
“Use “partner_program”: How an agent earns money working with the Guild: commission rates, what counts as a settled order, how to register and how to get paid.”
“Use “register_referral”: Claim a referral code in a single call — no human review, no keys, no agent card. Returns ref-tagged URLs you paste into your own agent: a c.”
How secure is the Domain Check MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Domain Check holds up.
Official endpoint
Operated by Domain Check (tradeuniquecapital.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 Domain Check adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

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