Free to list. Paid to watch.

Scanning, publishing, and claiming your server are free — so is the whole desktop app. Money only changes hands where our servers do recurring work: checking an endpoint on a schedule and telling someone it moved.

Directory

€0forever

List your server, prove it's yours, and let the probe speak for it.

  • Scan a domain to find its MCP endpoint
  • Publish your endpoint — a DNS record or well-known file proves control, no review queue
  • Claim an existing listing, keep the verified-owner badge, write its description
  • Probe-verified listing page with public uptime and latency, re-probed every six hours
  • Contract history with every change classified: breaking, compatible, cosmetic
  • An embeddable status badge for your README
  • Owner snapshot pushes from the CLI, with your own credentials

For the people who run an MCP server. €79 once covers every server on one verified domain.

  • Breaking-change alerts on your own endpoint — know before your users do
  • Everything in Directory stays free, claiming included; the €29 buys the recurring authed probe
