Tools
| Tool | Description | Behaviour |
|---|---|---|
| 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. | Not declared |
| 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). | Not declared |
| convert_timestamp | Convert a Unix timestamp (seconds, milliseconds, microseconds or nanoseconds, auto-detected) to a readable date, or a date/time string (e.g. 2026-12-25 09:00, read in the given time zone unless it has its own offset) to a Unix timestamp. Also returns weekday, ISO week and how long ago or until. | Not declared |
| 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. | Not declared |
| date_calc | Exact calendar maths. With end: days between two dates (plus weeks, months+days, weekdays Mon-Fri, weekend days). With add_days/add_weeks/add_months/add_years (negative to subtract): the resulting date and weekday; business_days=true skips weekends. Use this instead of counting days yourself. | Not declared |
| 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). | Not declared |
| 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. | Not declared |
| get_current_time | Get the exact current date and time (you cannot know it otherwise). Returns Unix seconds and milliseconds, ISO 8601 in UTC and in the requested IANA time zone, weekday, ISO week and day of year. | Not declared |
| 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. | Not declared |
| 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). | Not declared |
| 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. | Not declared |
| reverse_dns | Reverse DNS (PTR) lookup for an IPv4/IPv6 address, with forward-confirmation check. | Not declared |
| subnet_calc | IPv4/IPv6 CIDR subnet calculator: network, netmask, wildcard, broadcast, first/last usable host, total and usable addresses, block type. | Not declared |
| validate_ip | Check whether a string is a valid IPv4 or IPv6 address and classify it. | Not declared |
| 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. | Not declared |
