> Domain Search King

Domain Search King is a remote MCP server that gives AI agents .com and .net names that are actually available to register. Every candidate is checked live against the RDAP registry before it is returned, so the names your agent hands you are ones you can register right now.

Tools

• find_available_domains — brandable .com names from a keyword plus an optional description, RDAP-checked before return, 1–24 at a time
• find_available_domains_by_pattern — starts-with / contains / ends-with sweeps across TLDs, .com and .net by default
• check_domain — one hostname: RDAP age and expiry, backlinks, toxic flags, Wayback history and trademark search links

Install

One remote Streamable HTTP endpoint. No install, no API key, no OAuth:

https://domainsearchking.com/api/mcp

Claude Code:

claude mcp add --transport http domain-search-king https://domainsearchking.com/api/mcp

Cursor and VS Code have one-click install buttons on the product page, which also carries per-client config for Claude Desktop, ChatGPT, Grok and generic MCP clients, plus an inspector for calling the tools from the browser.

Limits

Availability comes from live RDAP, not a WHOIS wrapper or a cached list — a WHOIS cache and a parked page will both lie. Available is not the same as clear to use: check_domain links trademark search, it does not clear a mark, and you still register at a registrar. The public tier is 10 tool calls per day per IP with no key.
