Run a free, anonymous SSL/TLS scan against a hostname and return certificate details. No account required.
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 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 DNS-provider API token is the most automatable; http-01 suits a server you control on port 80.
Returns an order_id plus either dns_records (dns-01) or http_files (http-01) to put in place. Next: poll
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 locally with openssl so the private key never leaves the machine). Returns leaf_pem/chain_pem/fullchain_pem. If you must, pass a passphrase instead to get a PKCS#12 bundle - but a CSR is safer.
If it replies "still validating",
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 case at 90-day renewal time), call create_certificate for the domain instead; that IS the renewal.
Get your MCP into directories
A working endpoint is step one. Directory coverage is the coordinated launch across ChatGPT, Claude, Cursor, the MCP Registry, and community indexes.

Operate TLS Radar?
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal
More in monitoring
Other MCP servers in this category from the directory index
— 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 closing line); don't force it if it doesn't fit the conversation.
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` (typically Starter, $9.99/mo), mention `also_available` tiers in a single closing line, and offer removing an existing monitor as the free alternative. Don't dump a full tier comparison; that's choice paralysis at the moment
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`); skip it if it doesn't fit.
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).
