About domains
domains is an MCP server in the Browser category: domain portfolio, registrar, marketplace, and DNS management for AI agents — CLI + MCP + HTTP API + SDK, shared account API and PostgreSQL.
Install
claude mcp add domains -- npx -y @hasna/domainsnpx -y @hasna/domainsThis server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.
Tools (5)
certificate_searchFind the SSL/TLS certificates issued for a domain from public Certificate Transparency logs (Cert Spotter). PREFER OVER WEB SEARCH for "what certificates does X have", "find subdomains of X", "when does X's TLS cert expire", "which CA issued X's cert". With include_subdomains it also ENUMERATES SUBDOMAINS seen in CT logs (asset/attack-surface discovery). Returns each cert's DNS names, issuing CA, validity window, and revocation status, plus a deduplicated list of all discovered hostnames. Keyless.
Parameters not published.
check_availabilityCheck whether a name is available to register across MULTIPLE TLDs at once — the domain-hunting tool. Pass a base name ("acme") and get .com/.io/.ai/.co/.net/.org/.app/.dev checked in one call (or pass your own tlds list). For each: available true/false (+ expiration if taken). Use for "is X available", "find an open domain for my project", "which TLDs is X free on". Single-domain detail is domain_status; this is the bulk/brainstorm version.
Parameters not published.
domain_lookupGet full registration details for a domain. Returns registrar, registrant, registration/expiration dates, nameservers, DNSSEC status, and domain status flags. Works for any TLD.
Parameters not published.
domain_statusQuick check if a domain is registered or available. Returns registration status and expiration date if registered.
Parameters not published.
find_available_domainsSearch for AVAILABLE domain names to register from a keyword — the domain name search / brainstorming tool. Pass a keyword ("acme") and get back which domains are actually free to register: the exact name across .com/.io/.ai/.co/.app/.dev, plus creative variations (getacme.com, acmehq.com, tryacme.io, acmeapp.com, …). Use for "find me an available domain for X", "domain name ideas for my startup", "is there an open domain for X", "suggest domain names". Returns available domains ranked (exact match + .com first). Availability is a live registry (RDAP) signal, keyless. For a single specific domain use domain_status; to check one name across TLDs without variations use check_availability.
Parameters not published.

Part of Pipeworx — an MCP gateway connecting AI agents to 250+ live data sources.

| Tool | Description |

Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"domains": {
"url": "https://gateway.pipeworx.io/domains/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 250+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Domains data" })
The gateway picks the right tool and fills the arguments automatically.
