Compatible with every major AI agent and IDE
What is the WhoisXML MCP Server?
Connect the WhoisXML API to your AI agent to perform deep network reconnaissance and data validation through natural language.
What you can do
- WHOIS Lookups — Retrieve parsed and raw registration data, including registrar info and creation dates for any domain.
- IP Geolocation — Instantly identify the country, city, ISP, and coordinates of any IP address.
- Email Verification — Validate email syntax, check MX records, and detect disposable addresses to ensure data quality.
- Domain Availability — Perform lightweight checks to see if a domain name is available for registration.
How it works
- Subscribe to this server
- Enter your WhoisXML API Key
- Start querying domain and network data from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Security Researchers — Quickly investigate suspicious domains or IP addresses during incident response.
- Developers — Integrate domain availability and email validation checks into your workflow without leaving the editor.
- Marketers & Sales — Verify lead lists and research company domain ownership for better outreach.

Why VS Code Copilot?
GitHub Copilot Agent mode brings WhoisXML data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 4 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.
- —
VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor
- —
Project-scoped MCP configs (
.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access - —
Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop
- —
GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services

How Vinkius secures
WhoisXML for VS Code Copilot
Every tool call from VS Code Copilot to the WhoisXML MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can I check if a domain is available for registration?
Yes! Use the check_domain_availability tool. It provides a lightweight check to see if a specific domain name is currently available.
How do I find the physical location of an IP address?
Simply use the get_ip_geolocation tool with the target IP. The agent will return the country, city, latitude, longitude, and ISP information.
Can this tool detect disposable or fake email addresses?
Yes. The verify_email tool checks email syntax, MX records, and SMTP connections, and specifically flags disposable email providers.
Which VS Code version supports MCP?
MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.
How do I switch to Agent mode?
Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.
Can I restrict which MCP tools Copilot can access?
Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.
Does MCP work in VS Code Remote or Codespaces?
Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
MCP tools not available
Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
