What the publisher says

From the LinkPreflight repository's README, as published. We do not edit it. Read it on GitHub

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.

  • Site and docs: https://linkpreflight.dev
  • MCP endpoint: https://linkpreflight.dev/mcp
  • API: GET https://linkpreflight.dev/v1/preflight?url=example.com
  • Free: 200 checks a day. Packs: $10 for 25,000 checks.

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.

Nothing above is checked by us. What we check is on the safety report.
