Inject Live Domain Data into Code

The `get_whois_record` tool lets the AI fetch WHOIS data, which you can then use to write working code. The agent generates functions that incorporate this live API response, not just stubs. Want to check if a domain is available? Call `check_domain_availability`, and Cursor injects the 'available' or 'taken' status directly into your script's logic.

Map IPs When Coding

When you need location context, use `get_ip_geolocation`. The AI calls this function, grabs the coordinates, and uses them to populate a variable in the code block you’re writing. It's perfect for setting up data models that depend on IP address geography. This keeps your workflow focused entirely on coding.

Validate Inputs Before Commit

Never trust user input, especially emails. Use `verify_email` to check if an email is active before the code even ships. The agent handles this call and writes validation logic using the success/fail status. You can also use `get_whois_record` alongside this process for deep identity checks on related domains.

Setup guide

Set up WhoisXML MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the WhoisXML MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent WhoisXML transactions." If the MCP tools are loaded correctly, Cursor will call the WhoisXML tools automatically. You can also check Settings → MCP for a green status indicator.
