Tools

12 tools listed at last check
  • get_my_ip Return the public IP address (and ISP, ASN, location, timezone) of the caller as seen by FernTool. Note: for remote agents this is the IP of the machine calling the MCP server.
  • lookup_ip Validate an IPv4/IPv6 address and return its version, scope (public/private/loopback/...), country, ASN and network owner (DB-IP Lite + IPtoASN data).
  • validate_ip Check whether a string is a valid IPv4 or IPv6 address and classify it.
  • batch_lookup_ip Look up 1-100 IPv4/IPv6 addresses at once. Each result has version, scope, country, timezone, ASN, network owner and flags (is_tor, is_datacenter, provider).
  • whois_lookup WHOIS via RDAP for a domain (registrar, created/expiry dates, status, nameservers, DNSSEC), an IP address (network name, range, owner org, country, abuse contact) or an ASN like AS13335.
  • dns_lookup Resolve DNS records for a domain via Cloudflare 1.1.1.1 DNS-over-HTTPS. Types: A, AAAA, MX, TXT, NS, CNAME, SOA (default: all).
  • reverse_dns Reverse DNS (PTR) lookup for an IPv4/IPv6 address, with forward-confirmation check.
  • subnet_calc IPv4/IPv6 CIDR subnet calculator: network, netmask, wildcard, broadcast, first/last usable host, total and usable addresses, block type.
  • estimate_ai_cost Estimate token count and USD API cost of a text across major AI models (OpenAI GPT, Anthropic Claude, Google Gemini), and whether it fits each context window. Token counts are approximate. Pass text, or tokens directly.
  • make_qr_code Create a static QR code (never expires) for a URL, Wi-Fi string (WIFI:T:WPA;S:name;P:pass;;), mailto:, tel: or any text up to 2000 characters. Returns an SVG string plus a ferntool.com image URL that renders the same code.
  • count_words Exactly count words, characters (with and without spaces), sentences and paragraphs in a text, with reading/speaking time and the most repeated words. Use this instead of estimating counts yourself.
  • ai_service_status Live status of AI services (ChatGPT/OpenAI, Claude, Gemini API, GitHub Copilot, Perplexity, Cohere) read from their official status pages, cached ~60s. level is up, degraded, down or unknown.
