Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@whois-mcp look up whois information for example.com"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

工具 Tool | 描述 Description |
whois_lookup | Look up domain information using WHOIS protocol (port 43). Queries authoritative WHOIS servers for domain registration details including registrar, registrant, dates, nameservers, and status. Supports 1,260+ TLDs. |
refresh_whois_servers | Refresh the WHOIS server dictionary by fetching the latest TLD list from IANA. This updates the list of available WHOIS servers for domain lookups. Run this periodically to ensure the server list is up-to-date. |
list_supported_tlds | List all supported TLDs (Top-Level Domains) that have WHOIS servers available. Returns the complete list of TLDs that can be queried. |

Scored across 3 tools
Each tool has a clearly distinct purpose with no overlap: list_supported_tlds enumerates available TLDs, refresh_whois_servers updates the server list, and whois_lookup performs domain queries. The descriptions reinforce these distinct roles, making misselection unlikely.
All tools follow a consistent snake_case naming pattern with clear verb_noun structures (list_supported_tlds, refresh_whois_servers, whois_lookup). The naming is predictable and readable across the set.
Three tools is well-scoped for a WHOIS server, covering core functionality: listing TLDs, refreshing data, and performing lookups. Each tool earns its place without being excessive or insufficient for the domain.
The toolset provides complete coverage for WHOIS operations: it supports discovery (list_supported_tlds), maintenance (refresh_whois_servers), and core querying (whois_lookup). There are no obvious gaps for typical agent workflows in this domain.
