About

Live domain expiry, lifecycle stage, drop date and SSL checks from the registry over RDAP.

Security Report

7.8
Moderate7.8Low Risk

This is a benign, read-only domain and SSL lookup server that queries public RDAP registries and TLS endpoints without requiring credentials, which fits its purpose. The main concerns are low-severity: a third-party RDAP fallback (rdap.org) can receive queried domain names when the IANA bootstrap fails, and certificate verification is intentionally disabled for the SSL check. Neither is a malicious pattern, and no data exfiltration or dangerous code execution was found. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.

DropPerch MCP server

Ask your AI assistant when a domain expires, what lifecycle stage it is in, when it will drop, or when its SSL certificate runs out. The answers are read live from the domain's own registry over RDAP, not from a cached WHOIS copy.

  • No API key, no account. Each lookup goes from your machine straight to the authoritative registry. Nothing passes through a DropPerch server.
  • Works in Claude Desktop, Claude Code, Cursor, VS Code, Windsurf and any other MCP client that runs stdio servers.
  • MIT licensed. Made by DropPerch, the domain expiry monitor.

Tools

ToolWhat it answers
check_domainExpiry date, days left, lifecycle stage (active, grace, redemption, pending delete), registrar, nameservers, status codes, registration date, likely drop date
check_domainsThe same for up to 50 domains at once, with the soonest expiry called out
domain_drop_dateWhen an expiring or expired domain will be deleted and become registrable
ssl_certificateCertificate issuer, expiry date, days left, and whether browsers trust it

Try asking:

  • "When does github.com expire, and who is the registrar?"
  • "Check these client domains and tell me which ones expire in the next 60 days: …"
  • "Is old-brand.com in redemption? When would it drop?"
  • "Is the SSL certificate on our site about to expire?"

Install

You need Node.js 20 or newer.

Claude Code

claude mcp add dropperch -- npx -y dropperch-mcp

Claude Desktop, Cursor, Windsurf. Add this to the client's MCP config (claude_desktop_config.json, ~/.cursor/mcp.json, …):

{
  "mcpServers": {
    "dropperch": {
      "command": "npx",
      "args": ["-y", "dropperch-mcp"]
    }
  }
}

VS Code (.vscode/mcp.json):

{
  "servers": {
    "dropperch": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "dropperch-mcp"]
    }
  }
}

Good to know

  • Some TLDs publish no RDAP service (.de is one), and some publish no expiry date (SIDN's .nl). The tools say so rather than guess.
  • Drop dates follow ICANN timelines for gTLDs: up to 45 days of auto-renew grace, 30 days of redemption, then about 5 days of pending delete. Country-code TLDs set their own rules, so no date is estimated for them.
  • A 404 from the registry is an answer: the name is not registered.

Ongoing alerts

These tools check once, when you ask. To be emailed before a domain expires, when it enters redemption or pending delete, when it drops, or when its certificate is about to lapse, watch it on DropPerch. It's free for a small watchlist. Each tool result includes a monitor_url that opens signup with the domain filled in.
