Tools 16 found in our last check
check_domain_healthCheck the live SSL/TLS certificate (validity + expiry + issuer), DNS records (A/AAAA/MX/NS resolution), and domain-registration (RDAP) expiry of any public hostname. Each leg fails soft and is reported independently.
check_agent_readinessScore how ready a website is for AI agents and answer engines. Fetches /llms.txt, /robots.txt, and the homepage and returns a letter grade with per-signal findings. No browser rendering or LLM call — deterministic HTTP/parse.
check_mcp_healthHealth-check a live MCP (Model Context Protocol) server by URL: performs a real JSON-RPC initialize handshake, then tools/list, and returns whether it is up/degraded/down, its protocol version, server name/version, the callable tool/resource/prompt inventory, transport, and hand…
check_email_blacklistCheck whether a domain or IP is listed on the major DNS blocklists (DNSBLs) that mail providers consult before accepting mail — the usual reason legitimate mail silently lands in spam. Returns each zone checked, whether it is listed, and the return code. Deterministic DNS lookup…
check_broken_linksScan one web page for dead links (4xx/5xx/unreachable) and mixed content (http subresources on an https page). Returns each link with its status. Single-page scan, not a crawl — pass the exact page URL. Rate-limited to a few scans per minute, so batch calls will be throttled.
list_vendor_statusList the current operational status and recent incidents of every third-party vendor Merlonix monitors (e.g. Cloudflare, GitHub, Stripe). Returns each vendor's slug, current status, and 24h incident count.
get_vendor_statusGet the current status plus 30-day status history of one monitored vendor by slug (e.g. "cloudflare"). Use list_vendor_status to discover valid slugs.
list_plansList Merlonix subscription plans and pricing (Starter, Team, Agency, Compliance) with their monitoring limits.
list_my_assetsList the monitored assets (websites/domains) in YOUR Merlonix account. Returns each asset id, hostname, type, and monitoring status. Requires an API key (Authorization: Bearer mk_… from app.merlonix.com → Settings → API keys).
get_asset_checksGet the latest check results (SSL, DNS, uptime, heartbeat, port) for ONE of your monitored assets, by its asset id (from list_my_assets). Requires an API key.
list_my_alertsList recent alerts across YOUR monitored assets (SSL changes, downtime, DNS drift, vendor incidents, etc.) with their severity and lifecycle status. Requires an API key.
create_assetStart monitoring a new asset (website/domain) in YOUR Merlonix account. Provide a hostname and asset_type; optionally a label and which checks to enable. Returns the created asset. Requires an API key with write scope. Subject to your plan asset quota (a full or non-paying plan…
update_assetUpdate one of YOUR monitored assets by its asset id (from list_my_assets): relabel it or toggle which checks run. Returns the updated asset. Requires an API key with write scope.
delete_assetSTOP monitoring one of YOUR assets and remove it, by its asset id (from list_my_assets). This is irreversible — its check history goes too. Requires an API key with write scope.
acknowledge_alertAcknowledge one of YOUR alerts by its alert id (from list_my_alerts) — marks it as seen/being-handled without resolving it. Optionally attach a note. Requires an API key with write scope.
resolve_alertResolve one of YOUR alerts by its alert id (from list_my_alerts) — closes it. Optionally set resolution ("fixed" | "false_positive" | "wontfix") and a note. Requires an API key with write scope.
