domain-lookup-mcp is an MCP server used to query domain name information. Its core purpose is to enable MCP clients (such as AI applications or development tools that support the Model Context Protocol) to query domain names through a standard protocol.
In terms of main capabilities, the server prioritizes using the rdap(1) command to query domain names. If the RDAP query is unavailable or fails, it falls back to the whois(1) command, thereby obtaining domain registration-related data as much as possible. The project is implemented in the Go language, and the repository structure contains the files needed for building.
In terms of usage, the steps given in the materials are: first clone the repository; then run go build ./... to build; after the build is complete, point the MCP client to the generated binary file to use it.
The applicable scenarios are mainly MCP environments that need to integrate domain name query capabilities for AI agents or automated processes.
In terms of limitations, the materials do not provide information about query result fields, supported domain name types, rate limits, error handling details, or the required versions of the dependent rdap/whois tools; none of these are currently provided.
