Monitoring for agencies — uptime, SSL, DNS, blocklists, AI visibility, MCP health. 8 no-auth tools.
Server tool list (16)
Raw names from tools/list. Only developers need these.
| check_domain_health | Check 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_readiness | Score 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_health | Health-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 handshake latency. Deterministic — no LLM. Use it to verify your own MCP server is alive and spec-compliant. |
| check_email_blacklist | Check 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 lookups, no LLM. |
| check_broken_links | Scan 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_status | List 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_status | Get 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_plans | List Merlonix subscription plans and pricing (Starter, Team, Agency, Compliance) with their monitoring limits. |
| list_my_assets | List 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_checks | Get 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_alerts | List 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_asset | Start 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 returns an error). |
| update_asset | Update 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_asset | STOP 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_alert | Acknowledge 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_alert | Resolve 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. |
