Ip2whois MCP with Claude: Faster Domain Checks and Due Diligence
The short answer
Claude connects to Ip2whois through the Model Context Protocol, an open standard that acts as a secure adapter between the two. Once connected, Claude can ask Ip2whois for WHOIS records, read registration dates, contacts and nameservers, and summarise the results. Your team sets the permissions and approves any consequential action.
What is Ip2whois?
Ip2whois is a WHOIS lookup API. It returns detailed domain registration information and metadata for any domain, including creation dates, expiry dates, registrant and admin contacts, and nameserver details. Security teams, fraud analysts, marketing and legal departments, and web operations teams commonly use it to verify who owns a domain, how old it is and where it is hosted before they make a decision.
How Claude connects to Ip2whois through MCP
The Model Context Protocol, or MCP, is an open standard that lets Claude use other software securely. Think of it as a universal adapter between Claude and a tool. Your organisation decides what Claude may read and do, and access is limited to what each task needs.
Once Ip2whois is connected through its API key, Claude can typically look up a domain's WHOIS record, check how old it is and when it expires, list registrant and administrative contacts, and review nameserver information. You can ask questions in everyday language, such as which of a list of domains were registered in the last thirty days.
Permissions and approvals keep people in charge. Read-only lookups can run automatically, while anything that feeds a sensitive decision, such as blocking a sender or escalating a case, can be routed to a named reviewer first. Every request is logged so your team can see what was asked and answered.
What you can automate
Phishing and fraud screening
When a suspicious link or sender arrives, Claude can check how recently the domain was registered, who holds it and where its nameservers point. Analysts receive a short summary that highlights warning signs, such as a domain only days old using privacy-protected contacts. Humans decide whether to block, report or dismiss the case.
Vendor and supplier onboarding
Procurement teams often need to confirm that a supplier's web domain is genuine and long-established. Claude can run WHOIS checks on the domains listed in a supplier file and flag mismatches, such as a domain registered only weeks before a large contract was proposed. The results feed into the approval checklist.
Domain portfolio and renewal tracking
Companies with many domains risk letting one lapse. Claude can review expiry dates across the portfolio and produce a weekly list of domains due for renewal within sixty days, with the registrant contact named so the right person can act. This reduces the chance of lost brand assets.
Brand protection and trademark monitoring
Legal and brand teams can ask Claude to examine look-alike domains that imitate their brand. The summary covers creation dates, registrant details and nameserver patterns, helping the team decide whether to send a takedown request. Legal review remains part of every decision.
Lead and market research
Sales and marketing operations teams can check the age and registration details of prospect websites to better understand the businesses they target, within the limits of data protection rules. Claude can organise these findings into a clean table for the CRM.
An end-to-end workflow: Suspicious domain triage for the finance team
TriggerAn invoice or payment-change request arrives by e-mail containing a link or a new sender domain.
Claude extracts the sender and linked domains from the e-mail.
Claude queries Ip2whois for each domain's creation date, expiry date, registrant details and nameservers.
Claude compares the results with the approved supplier list held in the ERP system.
Claude writes a short risk summary, marking any domain younger than the supplier's known history.
The summary is posted to a ticket in the service desk for the finance controller to review.
The controller approves or rejects the payment change before any change is made in the ERP.
OutcomeSuspicious payment requests are caught earlier, and the finance team spends less time on manual checks while keeping final approval with a person.
How we set it up
Free automation audit
We review your current processes and identify where domain checks, renewals or fraud screening take up staff time. You receive a clear list of workflows worth automating, at no cost.
Secure connection
We connect Claude to Ip2whois using your API key, stored in a secure secrets manager with least-privilege access. Only the lookup functions your workflows need are enabled.
Workflow design
We map the end-to-end process across Ip2whois and your other systems, such as Microsoft 365, your CRM, ERP or ticketing tool. We define which actions run automatically and which need a named approver.
Testing with real cases
We test the workflow against past domains and cases from your own records, checking accuracy and how clearly the summaries read. We adjust prompts and rules until your team is satisfied.
Launch, monitoring and training
We launch with monitoring and audit logs enabled and train your team on how to use and review the results. We remain available to tune the workflow as your needs change.

For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom must align domain data use with their privacy and sector rules, including UK GDPR. In India, the Digital Personal Data Protection Act, 2023 governs how personal details in registration records are handled. Companies in the UAE and Saudi Arabia must observe their local data protection laws when storing or processing contact information. We choose the Claude hosting region in India, the United States, the United Kingdom or the European Union to match your data requirements.

Frequently asked questions
What does the Ip2whois MCP server do?
The Ip2whois MCP server lets Claude request WHOIS records through a standard, controlled channel. It can retrieve domain registration details, registrant and admin contacts, creation and expiry dates, and nameserver information. Claude then reads and summarises those results in plain language, so staff can ask questions without writing queries themselves.
Is connecting Ip2whois to Claude secure?
Yes, when it is set up correctly. We use your Ip2whois API key stored in a secure secrets manager, grant only the lookup functions needed, and log every request. Consequential actions require human approval, so Claude never acts on a sensitive decision alone.
What can Claude do with Ip2whois once connected?
Typically Claude can look up single or multiple domains, check how old a domain is and when it expires, list contact details where the data is available, and review nameserver patterns. It can compare results against your records and produce summaries, tables or tickets for your team to review.
How long does setup take?
Setup time depends on how many workflows you need and how many systems they touch. A focused single workflow is often ready within a few weeks, including the free audit, testing with real cases and staff training. We agree a timeline with you after the audit.
What plan or permissions do I need?
You need an active Ip2whois account that provides an API key with access to the lookup functions your workflows use. The exact access depends on your Ip2whois arrangement, so we check this during the free audit and confirm your key permissions before building anything.
