## Description
WHOIS, DNS, SSL, and domain availability lookups for AI assistants

## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "whoisjson": {
    "command": "npx",
    "args": ["-y","whoisjson"]
  }
}
```
