Is this your server? Own a server? ToolFit hosted watch re-checks it every 24 h ($0.25 per 30 days) or 6 h ($0.60) and sends you an HMAC-signed webhook when its tools or grade change: POST https://api.youraitools.co/toolfit/v1/watch. To opt out, see About & opt-out.

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. params: hostname* |
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. params: hostname* |
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. params: url* |
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. params: domain* |
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. params: url* |
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. params: none |
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. params: slug* |
list_plans | List Merlonix subscription plans and pricing (Starter, Team, Agency, Compliance) with their monitoring limits. params: none |
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). params: none |
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. params: asset_id* |
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. params: none |
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). params: hostname*, asset_type*, label, ssl_enabled, dns_enabled, domain_enabled, uptime_check_url |
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. params: asset_id*, label, ssl_enabled, dns_enabled, domain_enabled |
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. params: asset_id* |
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. params: alert_id*, note |
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. params: alert_id*, resolution, note |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
