16 tools

• scan_domain

  Run a free, anonymous SSL/TLS scan against a hostname and return certificate details. No account required.

• create_certificate

  Start issuing a FREE Let's Encrypt certificate for a domain (no account required). Step 1 of 3. Lifetime is Let's Encrypt's default: 90 days today, 64 days from 2027-02-10; read the real expiry from the issued certificate. Pick a validation method with `challenge`: "dns-01"…

• check_certificate_propagation

  Check whether the DNS TXT records for a certificate order have propagated (Cloudflare/Google/Quad9). Step 2 of issuance - poll until all_found is true, then call finalize_certificate. Returns per-record resolver results.

• finalize_certificate

  Finalize and issue a certificate order in one call: validates the DNS challenges, waits for Let's Encrypt, and returns the issued cert. Step 3 of issuance - call after check_certificate_propagation reports all_found. STRONGLY PREFER passing csr_pem (generate the key + CSR…

• get_certificate_status

  Return the current state of a certificate order (dns_pending, validating, ready, completed, failed) and per-authorization Let's Encrypt statuses. Use it to resume an interrupted issuance.

• renew_certificate

  Renew a certificate by cloning a recent order (requires the original order_id; Beacon purges orders after ~24h). Returns a new order_id and fresh DNS TXT records - then poll check_certificate_propagation and call finalize_certificate. If you don't have an order_id (the usual…

• get_account

  Return the current user's plan, limits, and usage so the client can render upgrade nudges proactively.

• list_monitors

  List all certificates currently being monitored across the user's teams. If the response's structuredContent includes a `nudge` object, the user is at their monitor cap - surface it casually ONCE (lead with `nudge.recommended_upgrade`, mention `nudge.also_available` in one…

• add_monitor

  Add a domain to ongoing certificate monitoring with expiry alerts. Requires authentication (the user runs /mcp once). If the plan's monitor limit is reached, the response's structuredContent carries a limit-reached payload - when relaying it, LEAD with `recommended_upgrade`…

• add_monitors

  Add multiple domains to monitoring in one call. Returns a per-domain status so the caller can show partial-success outcomes. Honors the same plan-limit checks as add_monitor.

• remove_monitor

  Stop monitoring a domain. Accepts the domain name or the host_id returned by list_monitors.

• list_expiring_certificates

  Return monitored certificates expiring within N days. Defaults to 30. If the response's structuredContent includes a `nudge` object, the user is watching enough soon-to-expire certs to benefit from a higher tier - mention it casually ONCE (lead with `nudge.recommended_upgrade`)…

• get_scan_history

  Return recent scan results for a domain the user monitors. Useful for spotting issuer changes, grade drops, or vulnerability appearances over time.

• export_monitors

  Dump the user's monitors as a JSON structure suitable for backup, migration, or infrastructure-as-code workflows. Tokens and PII are NEVER included - only domain configuration.

• import_monitors

  Create monitors from a JSON structure (typically produced by `export`). Skips domains the user is already monitoring; honors the plan's domain limit. Returns a per-domain status.

• invite_team_member

  Invite a user to a team by email. Defaults to the user's current team. Honors the plan's seat limit (returns the same upgrade payload as add_monitor when the cap is hit).
