Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
cruise
cruise_options
The regions, cruise lines (with tier), departure ports and months on sale, each with its count of sailings. These are the values the search filters accept.
get_cruise
Everything about one sailing: day-by-day itinerary, current price of each cabin grade with the date it was read (and which have no price listed),each grade against its usual price, the fare's own price history, the same itinerary on other dates with prices, the best thing to do at each port (verified seller and price where we have one, and its booking page), and book_url.
compare
compare_cruise_lines
Side-by-side cruise lines for the same kind of cruise (a region, departure port or port visited, plus dates): each line's number of sailings, ships, median and lowest price per person per night in one cabin grade, and its cheapest sailing with book_url. Answers "Alaska in July: Princess or NCL?".
cruises
search_cruises
Accepts the request in plain words (q) or as fields. Searches every sailing Fantasize tracks (23 cruise lines, ~30,000 sailings, priced every night) by region, dates, departure port, ports visited, line, length, cabin and budget. Returns up to 25 sailings with the price per person (taxes and port fees in), per night and for a cabin of two, every cabin grade's price, whether the fare is low, typical or high against that sailing's usual price, the ports of call, and book_url - a link the person opens to book that exact sailing. Default ranking is best_value (furthest below its usual price).
fare
fare_index
Fantasize's Cruise Fare Index: how the price of the same cruises moves night to night, from our own nightly pricing of every sailing (each sailing compared only with its own earlier price, so new sailings and sell-outs never move it). Returns the overall level and its change, and the same by cruise company (with stock ticker), cruise line, region and months to departure, plus the cruise companies' latest press releases. Name a group (e.g. "Royal Caribbean Group", "Alaska", "3-6 months out") for its daily series.
last
last_minute_cruise_deals
Today's report of balcony and suite cabins on cruises leaving North American ports within about 21 days, each measured against the book-ahead price for the same ship, grade and length (rebuilt every morning). Filter by departure port or region. Some late fares are dearer than booking ahead; those show a negative percent.
port
port_guide
Fantasize's ranked guide to one cruise port: the most extraordinary things to do, the operator who runs each, the verified seller and price where we have one, a booking page for each, and how many sailings call there.
price
check_price
Judge a price someone was quoted or already paid for one sailing: whether it is low, typical or high against that sailing's usual price for the cabin, today's listed fare beside it, the lowest fare read in 120 days, a plain one-paragraph answer to quote, and watch_url where the person can be emailed if the fare drops below their price. Name the sailing by sailing_id, a fantasize.net /cruise/ link, or ship plus depart_date.
report
report_problem
Report a problem you found while using these tools: a price that does not match the booking page (wrong_price), a sailing that cannot be bought (not_for_sale), a wrong route or ports (wrong_itinerary), a book_url that does not open the sailing (broken_link), results that miss or do not fit the request (irrelevant_results, missing_sailings), or duplicates. Include sailing_id when it is about one sailing, and the search you ran when it is about results. Reports carry no personal details; a person at Fantasize reads every report.
request
request_trip_help
Sends one email to the person's own address. Their click in that email confirms the request; only then does it reach a Fantasize cruise specialist, who replies to them by email to help plan and book the trip. Free; no account is created and nothing is charged. Takes the trip they want in a sentence or two, and optionally dates, travellers, budget, home city and the sailing ids they looked at.

How MCP servers expose tools in the first place →
Is Fantasize cruise finder working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 598 ms. The bar chart above shows every period we have measured.
How do I connect Fantasize cruise finder?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Fantasize cruise finder need an API key?
No. Fantasize cruise finder completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Fantasize cruise finder?
It answers our handshake in 598 ms on average, which is faster than 18% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
