TLS Radar

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

Start issuing a FREE 90-day Let's Encrypt certificate for a domain (no account required). Step 1 of 3. Pick a validation method with `challenge`: "dns-01" (default; publish a TXT record; covers apex + www) or "http-01" (serve a file over HTTP on port 80; issues the exact domain only). dns-01 with a

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 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 locally with openssl so the

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 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 case at 90-day renewal t

OBSOLETE - do not call. The cert→monitoring handoff is server-side now (issue via create_certificate, which records the order itself). This tool is kept only so old plugin versions that still call it don't error; it remains idempotent and harmless.

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

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 closing line); don't force

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` (typically Starter, $9.99

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.

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

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`); skip it if it doesn'

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

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.

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 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).
