MCP to lookup whois information
If you want an AI assistant working directly with Whois MCP, the whois mcp mcp server is the bridge. MCP to lookup whois information.
Model Context Protocol server for whois lookups.
This MCP server allows AI agents like Claude Desktop, Cursor, Windsurf,.. etc to perform WHOIS lookups and retrieve domain details.
Once connected, the assistant can call these 4 tools directly:
whois_domain — Looksup whois information about the domainwhois_tld — Looksup whois information about the Top Level Domain (TLD)whois_ip — Looksup whois information about the IPwhois_as — Looksup whois information about the Autonomous System Number (ASN)The server is distributed via npm as @bharathvaj/whois-mcp, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Whois MCP sits in that group, and the shape of its toolset — whois_domain, whois_tld, whois_ip among others — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
| Tool | What it does |
|---|---|
| whois_domain | Looksup whois information about the domain |
| whois_tld | Looksup whois information about the Top Level Domain (TLD) |
| whois_ip | Looksup whois information about the IP |
| whois_as | Looksup whois information about the Autonomous System Number (ASN) |
