How to Use the IP2WHOIS MCP in Windsurf

Q: How does Windsurf use IP2WHOIS to check domain age?

Windsurf calls the checkdomainage tool to instantly find when a domain was registered. Cascade uses this data during security audits to flag suspicious, newly created domains.

Q: Can Windsurf check domain availability?

Yes, Cascade uses the checkdomainavailability tool to check if a domain is unregistered. This lets you quickly verify if a competitor or squatter has abandoned a brand asset.

Q: How do I check my IP2WHOIS API status in Windsurf?

You can run checkip2whoisstatus to verify your API connection and remaining credits. Windsurf displays the status in the Cascade panel to confirm your setup is active.

Let Windsurf autonomously chain registration checks and map infrastructure using live IP2WHOIS data directly in your editor.

Perplexity

Multi-step domain triage inside Windsurf

The `bulk_whois_lookup` tool lets Cascade audit whole batches of domains during incident triage without you prompting each step. The agent reads your security logs, pulls the suspicious domains, and runs them against the IP2WHOIS API to find malicious infrastructure. Cascade then chains `check_domain_age` to flag newly registered domains that often point to phishing campaigns. You get a clean, sorted list of threat indicators right in your Windsurf workspace without writing any custom parsing scripts.

Autonomous expiration monitoring with this MCP Server

This IP2WHOIS MCP Server exposes `check_domain_expiry` to let Cascade check your entire portfolio's status on its own. When you ask the agent to verify your domain health, it scans your codebase for active domains and pulls their expiration dates. Cascade doesn't stop at checking; it uses `get_registrar_info` to identify where each domain is held and whether any locks are missing. The agent then writes a markdown report of expiring assets directly into your project directory.

Shared hosting analysis on Windsurf

The `lookup_hosted_domains` tool allows Cascade to discover every domain sharing an IP address when you run a reverse lookup. By taking a target IP from your terminal output, Cascade maps the co-hosted sites and flags potential bad neighbors. Cascade automatically correlates this with `get_domain_contacts` to see if the same threat actor registered multiple sites on that server. It presents the entire footprint in your chat window so you can make fast mitigation decisions.
