Summary
A straightforward network diagnostics toolkit that wraps common operations you'd normally run from the command line or various web tools. It exposes DNS lookups, WHOIS queries, SSL certificate checking, and HTTP status code verification through public APIs, so you're not parsing dig output or scraping random websites. Useful when you're debugging connectivity issues, verifying domain configurations, or checking certificate expiration dates directly from Claude without switching contexts. The author maintains it as part of toolcompare.fyi, a site comparing tools for freelancers and small teams. Nothing fancy here, just reliable network utilities accessible through the MCP protocol.
Keeps your Mac awake while Claude Code, Codex or Cursor works. Lets it sleep when they are done.
