Cloudflare-Workers
MCP tools on Cloudflare, Part 1: Stateless
A remote MCP server on Cloudflare Workers that exposes domain lookup tools to any MCP client — Claude Desktop, Claude Code, Cursor, anything that speaks MCP. The tools query RDAP, the modern replacement for WHOIS, for domain availability, IP addresses, and ASN data. The same Worker also serves a REST API for humans and scripts. Same business logic, two interfaces. The MCP endpoint lives at /mcp, the REST API at /check/<domain>.
