Whois Lookup
Performs whois lookup against domain, IP, ASN and TLD.
Overview
Whois Lookup is a tool that performs WHOIS lookups against domains, IP addresses, Autonomous System Numbers (ASN), and Top-Level Domains (TLD). It allows users to retrieve registration details about a domain name or IP address without needing to search through a browser.
To use Whois Lookup, you can install the MCP server using the command npx -y @bharathvaj/whois-mcp@latest. Once installed, you can configure it in your IDE (like Cursor or Roo Code) to access WHOIS information directly through AI agents.
- Retrieve domain registration details including owner information, registration dates, and status. - Supports WHOIS lookups for domains, IPs, ASNs, and TLDs. - Integration with AI agents for seamless querying.
- Checking domain availability for new projects.
- Finding out who owns a specific domain.
- Retrieving registration and expiration dates for domains.
- Analyzing IP address ownership and details.

Use these steps to connect Whois Lookup in Cursor, Claude, VS Code, and other MCP-compatible apps. The same JSON appears in the Use with menu above for one-click copy.
Cursor
Add this to your .cursor/mcp.json file in your project root, then restart Cursor.
.cursor/mcp.json
{
"mcpServers": {
"whois-lookup-bharathvaj-ganesan": {
"command": "npx",
"args": [
"-y",
"@modelcontextprotocol/server-whois-lookup-bharathvaj-ganesan"
]
}
}
}Claude Desktop
Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.
~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)
{
"mcpServers": {

]
}
}
}Claude Code
Add this to your project's .mcp.json file. Claude Code will detect it automatically.
.mcp.json (project root)
{
"mcpServers": {
"whois-lookup-bharathvaj-ganesan": {

"args": [
"-y",
"@modelcontextprotocol/server-whois-lookup-bharathvaj-ganesan"
]
}
}
}VS Code (Copilot)
Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

}FAQ
What information can I get from a WHOIS lookup?
You can retrieve details such as domain name, registrar name, registrant details, registration and expiry dates, name servers, and contact information.
Is there a limit to the number of lookups I can perform?
There may be rate limits imposed by WHOIS databases, but the tool itself does not limit the number of queries.
Can I use this tool for any domain?
Yes, you can perform lookups for any registered domain, but privacy settings may restrict access to certain registrant details.7:["$","div",null,{"className":"container mx-auto flex flex-col gap-4","children":["$L26","$L27",["$","$L28",null,{"currentProject":{"id":2046,"uuid":"36f27248-86e6-4e82-b201-6bc9554b7640","name":"Whois Lookup","title":"Whois Lookup","description":"Performs whois lookup against domain, IP, ASN and TLD.","avatar_url":null,"created_at":"2025-03-05T19:05:30.443+00:00","updated_at":"2025-03-23T14:55:36.673+00:00","status":"created","author_name":"bharathvaj-ganesan","author_avatar_url":null,"tags":"whois,domain-lookup,network-tools","category":"research-and-data","is_featured":false,"sort":1,"url":"https://github.com/bharathvaj-ganesan/whois-mcp","target":"_self","content":"$29","summary":"$2a","img_url":null,"type":null,"metadata":null,"user_uuid":"15830ec8-1c1c-4bac-8a30-7a823b34c2b6","tools":null,"sse_url":null,"sse_provider":null,"sse_params":null,"is_official":false,"server_command":null,"server_params":null,"server_config":null,"allow_call":false,"is_innovation":false,"is_dxt":false,"dxt_manifest":null,"dxt_file_url":null,"is_audit":false},"randomProjects":[],"currentServerKey":"$undefined"}]]}]
