Merlonix Monitoring

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.

{
  "type": "object",
  "properties": {
    "hostname": {
      "type": "string",
      "description": "A public hostname, e.g. example.com"
    }
  },
  "required": [
    "hostname"
  ],
  "additionalProperties": false
}

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.

{
  "type": "object",
  "properties": {
    "hostname": {
      "type": "string",
      "description": "A public hostname, e.g. example.com"
    }
  },
  "required": [
    "hostname"
  ],
  "additionalProperties": false
}

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.

{
  "type": "object",
  "properties": {
    "url": {
      "type": "string",
      "description": "The MCP endpoint URL, e.g. https://example.com/mcp"
    }
  },
  "required": [
    "url"
  ],
  "additionalProperties": false
}

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.

{
  "type": "object",
  "properties": {
    "domain": {
      "type": "string",
      "description": "A public domain or IP address, e.g. example.com or 203.0.113.10"
    }
  },
  "required": [
    "domain"
  ],
  "additionalProperties": false
}

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.

{
  "type": "object",
  "properties": {
    "url": {
      "type": "string",
      "description": "The exact page URL to scan, e.g. https://example.com/pricing"
    }
  },
  "required": [
    "url"
  ],
  "additionalProperties": false
}

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.

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

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.

{
  "type": "object",
  "properties": {
    "slug": {
      "type": "string",
      "description": "Vendor slug, e.g. cloudflare"
    }
  },
  "required": [
    "slug"
  ],
  "additionalProperties": false
}

List Merlonix subscription plans and pricing (Starter, Team, Agency, Compliance) with their monitoring limits.

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

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).

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

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.

{
  "type": "object",
  "properties": {
    "asset_id": {
      "type": "string",
      "description": "The asset id from list_my_assets (a UUID)."
    }
  },
  "required": [
    "asset_id"
  ],
  "additionalProperties": false
}

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.

{
  "type": "object",
  "properties": {},
  "additionalProperties": false
}

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).

{
  "type": "object",
  "properties": {
    "hostname": {
      "type": "string",
      "description": "The hostname to monitor, e.g. example.com"

    }
  },

    "hostname",
    "asset_type"
  ],
  "additionalProperties": false
}

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.

{
  "type": "object",
  "properties": {
    "asset_id": {
      "type": "string",
      "description": "The asset id from list_my_assets (a UUID)."

    }
  },
  "required": [
    "asset_id"
  ],
  "additionalProperties": false
}

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.

{
  "type": "object",
  "properties": {
    "asset_id": {
      "type": "string",
      "description": "The asset id from list_my_assets (a UUID)."
    }
  },
  "required": [
    "asset_id"
  ],
  "additionalProperties": false
}

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.

{
  "type": "object",
  "properties": {
    "alert_id": {
      "type": "string",
      "description": "The alert id from list_my_alerts (a UUID)."
    },
    "note": {
      "type": "string",
      "description": "Optional note (max 500 chars)."
    }
  },
  "required": [
    "alert_id"
  ],
  "additionalProperties": false
}

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.

{
  "type": "object",
  "properties": {
    "alert_id": {
      "type": "string",
      "description": "The alert id from list_my_alerts (a UUID)."

        "fixed",
        "false_positive",
        "wontfix"
      ],
      "description": "Why the alert is being closed."
    },
    "note": {
      "type": "string",
