LinkPreflight

A remote MCP server and API for AI agents. One preflight(url) call tells you whether a link is safe, live, and what's behind it (status, redirects, dead or parked, phishing flags, content type, llms.txt) before your agent clicks or fetches it.

Pairs well with

  • Clearcrawl, from our studio: once a URL passes preflight, Clearcrawl turns it into clean markdown or JSON.
  • VibePicks, from our studio: one clear verdict per AI dev-tool job.
