Perplexity

Domain Availability Scripting

Scripting a domain sweep is easy using `check_domain_availability`. You pipe a list of potential domains into your agent, and it returns only those that are free for registration. This works perfectly in CI/CD pipelines. Instead of manually checking names, you set up a shell script to call the MCP Server's tool endpoint. The output is clean, allowing subsequent scripts to immediately act on the available domain name.

WHOIS and IP Mapping

The `get_whois_record` tool outputs structured data you can pipe into other utilities for parsing. You run this in a headless environment, pulling ownership details without needing any GUI. Need to track network activity? Use `get_ip_geolocation`. By piping the results of this tool, you can build geo-fencing scripts or audit logs that record where traffic originates from.

Bulk Validation and Auditing

You can validate large lists of contact information using `verify_email` for bulk auditing. This is ideal for pre-deployment checks on a massive list of user accounts. For full asset audits, combine `check_domain_availability` with `get_whois_record`. The resulting output provides both the immediate status (available/taken) and the historical ownership data.

Setup guide

Set up WhoisXML MCP in Claude Code

Prerequisites

Claude Code CLI installed (npm install -g @anthropic-ai/claude-code)
Active Vinkius subscription with a valid endpoint token

1

Run the add command

Open your terminal and run the command shown on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com. Use --scope user to make it available across all projects.
2

Verify the connection

Start a Claude Code session and type /mcp to list connected servers. You should see whoisxml-mcp with a green status indicator.
3

Start using tools

Ask Claude Code something like "Check my latest WhoisXML transactions." It will automatically discover and invoke the available WhoisXML tools.

Terminal

claude mcp add --transport http whoisxml-mcp https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp

Prerequisites

Claude Code CLI installed
Active Vinkius subscription with a valid endpoint token

1

Open the config file

Create or edit .mcp.json in your project root for project-level scope, or ~/.claude.json for user-level scope.
2

Add the WhoisXML MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Restart Claude Code

Start a new Claude Code session. Type /mcp to confirm the server is connected. The tools will be automatically available in your conversation.

  "mcpServers": {
    "whoisxml-mcp": {
      "type": "url",
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"

Common questions about WhoisXML MCP in Claude Code

You simply add a step to your workflow that calls the MCP Server. It executes `check_domain_availability` against a list of domains, and if any fail the check, the pipeline fails immediately, giving you instant feedback.

The server provides domain records, IP addresses, email formats, and raw WHOIS text. All of these are outputted as plain strings or structured JSON objects that your shell script can easily parse.

Absolutely. You don't have to run four separate commands. A single script wrapper calls the tools sequentially, piping results from `get_whois_record` into a logging utility and then running `verify_email` on any discovered contacts.

The server touches domain records, IP addresses, and email formats. When used in an automated terminal script, you control the entire output stream, allowing you to filter or redact sensitive ownership details before they hit disk storage.

It's for deep, non-interactive auditing. You run it when you need hard facts—like verifying a list of domains or mapping IP addresses—and you don't want to deal with any graphical interface.
