What this MCP does
Monitors websites and domains for uptime, SSL, DNS, blocklists, broken links, AI readiness, MCP health, alerts, and vendor incidents.
Capabilities

tools
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.
Idempotent
Input schema
{'type': 'object', 'required': ['alert_id'], 'properties': {'note': {'type': 'string', 'description': 'Optional note (max 500 chars).'}, 'alert_id': {'type': 'string', 'description': 'The alert id from list_my_alerts (a UUID).'}}, 'additionalProperties': False}
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.
Read only
Input schema
{'type': 'object', 'required': ['hostname'], 'properties': {'hostname': {'type': 'string', 'description': 'A public hostname, e.g. example.com'}}, 'additionalProperties': False}
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.
Read only
Input schema
{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'description': 'The exact page URL to scan, e.g. https://example.com/pricing'}}, 'additionalProperties': False}
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.
Read only
Input schema
{'type': 'object', 'required': ['hostname'], 'properties': {'hostname': {'type': 'string', 'description': 'A public hostname, e.g. example.com'}}, 'additionalProperties': False}
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.
Read only
Input schema
{'type': 'object', 'required': ['domain'], 'properties': {'domain': {'type': 'string', 'description': 'A public domain or IP address, e.g. example.com or 203.0.113.10'}}, 'additionalProperties': False}
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.
Read only
Input schema
{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'description': 'The MCP endpoint URL, e.g. https://example.com/mcp'}}, 'additionalProperties': False}
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).
Input schema
{'type': 'object', 'required': ['hostname', 'asset_type'], 'properties': {'label': {'type': 'string', 'description': 'Optional human label (max 120 chars).'}, 'hostname': {'type': 'string', 'description': 'The hostname to monitor, e.g. example.com'}, 'asset_type': {'enum': ['domain', 'hostname', 'certificate', 'dns_record'], 'type': 'string', 'description': 'Asset kind: "hostname" (a website/host), "domain", "certificate", or "dns_record".'}, 'dns_enabled': {'type': 'boolean', 'description': 'Monitor DNS records.'}, 'ssl_enabled': {'type': 'boolean', 'description': 'Monitor the TLS certificate (default on for hostnames).'}, 'domain_enabled': {'type': 'boolean', 'description': 'Monitor domain-registration (RDAP) expiry.'}, 'uptime_check_url': {'type': 'string', 'description': 'Optional URL to probe for uptime (enables uptime checks).'}}, 'additionalProperties': False}
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.
Destructive
Idempotent
Input schema
{'type': 'object', 'required': ['asset_id'], 'properties': {'asset_id': {'type': 'string', 'description': 'The asset id from list_my_assets (a UUID).'}}, 'additionalProperties': False}
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.
Read only
Input schema
{'type': 'object', 'required': ['asset_id'], 'properties': {'asset_id': {'type': 'string', 'description': 'The asset id from list_my_assets (a UUID).'}}, 'additionalProperties': False}
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.
Read only
Input schema
{'type': 'object', 'required': ['slug'], 'properties': {'slug': {'type': 'string', 'description': 'Vendor slug, e.g. cloudflare'}}, 'additionalProperties': False}
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.
Read only
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
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).
Read only
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
list_plans
List Merlonix subscription plans and pricing (Starter, Team, Agency, Compliance) with their monitoring limits.
Read only
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
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.
Read only
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
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.
Idempotent
Input schema
{'type': 'object', 'required': ['alert_id'], 'properties': {'note': {'type': 'string', 'description': 'Optional note (max 500 chars).'}, 'alert_id': {'type': 'string', 'description': 'The alert id from list_my_alerts (a UUID).'}, 'resolution': {'enum': ['fixed', 'false_positive', 'wontfix'], 'type': 'string', 'description': 'Why the alert is being closed.'}}, 'additionalProperties': False}
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.
Idempotent
Input schema
{'type': 'object', 'required': ['asset_id'], 'properties': {'label': {'type': 'string', 'description': 'New label (max 120 chars).'}, 'asset_id': {'type': 'string', 'description': 'The asset id from list_my_assets (a UUID).'}, 'dns_enabled': {'type': 'boolean', 'description': 'Enable/disable DNS monitoring.'}, 'ssl_enabled': {'type': 'boolean', 'description': 'Enable/disable TLS-certificate monitoring.'}, 'domain_enabled': {'type': 'boolean', 'description': 'Enable/disable domain-registration (RDAP) monitoring.'}}, 'additionalProperties': False}
