Monitoring for agencies — uptime, SSL, DNS, blocklists, AI visibility, MCP health. 8 no-auth tools.
Scored across 16 tools
Each tool targets a distinct resource and action. The five check tools are differentiated by their target (agent readiness, broken links, domain health, email blacklist, MCP health), and asset/alert management tools have clear CRUD/lifecycle boundaries. No two tools appear to overlap.
All 16 tools follow a consistent verb_noun pattern with lowercase and underscores (e.g., check_domain_health, create_asset, list_my_alerts). The verbs are clear and consistently used, making the API predictable.
16 tools is well-scoped for a monitoring service that spans asset management, alert lifecycle, multiple diagnostic checks, vendor status, and plan listing. Every tool has a distinct role and earns its place without redundancy.
The tool surface covers full asset CRUD (create, list, update, delete, get checks), alert lifecycle (list, acknowledge, resolve), and a broad set of standalone checks. Minor gaps like a direct 'get asset' endpoint or manual re-check are absent, but core workflows are fully supported.
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.
Inputs: alert_id (required), note.
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.
Inputs: hostname (required).
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.
Inputs: url (required).
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.
Inputs: hostname (required).
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.
Inputs: domain (required).
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.
Inputs: url (required).
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).
Inputs: hostname (required), asset_type (required), label, dns_enabled, +3 more.
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.
Inputs: asset_id (required).
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.
Inputs: asset_id (required).
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.
Inputs: slug (required).
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.
Inputs: no named parameters.
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).
Inputs: no named parameters.
List Merlonix subscription plans and pricing (Starter, Team, Agency, Compliance) with their monitoring limits.
Inputs: no named parameters.
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.
Inputs: no named parameters.
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.
Inputs: alert_id (required), note, resolution.
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.
Inputs: asset_id (required), label, dns_enabled, ssl_enabled, +1 more.
