Learn how to connect IP2WHOIS to Pydantic AI and start using 10 AI agent tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code.
What is the IP2WHOIS MCP Server?
Connect your IP2WHOIS account to any AI agent and access comprehensive domain intelligence through natural conversation.
What you can do
- WHOIS Lookup — Get complete registration records for any domain including dates, registrar, and contacts.
- Domain Age — Calculate how old a domain is in days and years.
- Expiry Monitoring — Check when domains expire and how many days remain.
- Registrar & Nameservers — Extract registrar details and DNS nameserver configurations.
- Availability Check — Determine if a domain is available for registration.
- Reverse IP — Find all domains hosted on a specific IP address.
- Bulk Lookup — Query up to 10 domains in a single operation.
How it works
1. Subscribe to this server
2. Enter your IP2WHOIS API key (free tier: 500 queries/month)
3. Start querying domains from Claude, Cursor, or any MCP client
Who is this for?
- Security Researchers — investigate domain ownership and infrastructure.
- Domain Investors — monitor expiry dates and check availability.
- IT Administrators — audit DNS configurations and shared hosting environments.

Frequently asked questions
Can I check if a domain is available for registration?
Yes! Use check_domain_availability with the domain name. It analyzes the WHOIS record to determine if the domain appears unregistered.
How many domains can I look up at once?
Use bulk_whois_lookup with a comma-separated list of up to 10 domains to get key registration details for each one in a single request.
Can I find which domains are hosted on a specific server?
Yes! Use lookup_hosted_domains with an IPv4 or IPv6 address to perform a reverse IP lookup and discover all domains on that server.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your IP2WHOIS MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
