`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` (it carries the plan name and price), 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 of action.	Add a domain to ongoing certificate monitoring with expiry alerts.

`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.

`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.

Returns per-record resolver results.	Not declared	Yes	Yes	Yes
`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" (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` until all_found, then call `finalize_certificate`. Strongly prefer the CSR path at finalize (the private key never leaves the user's machine). Issuing automatically offers the user ongoing monitoring by email once it completes - don't add a monitor manually afterward.

Not declared	Yes	Yes	No
`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", DNS hasn't fully propagated: re-check check_certificate_propagation and call again. Needs a locally-generated CSR (csr_pem) - requires a local shell with openssl. On a surface without one (e.g. a Claude.ai custom connector) this can't complete; it returns guidance to finish in Claude Code/Cowork or the web form. Scanning and monitoring work everywhere. On success the structuredContent carries a `handoff` object - relay `handoff.message` to the user and do NOT separately call add_monitor; the cert→monitoring handoff is automatic and server-side.
