How to connect Slicktrip MCP with DeepSeek Harness

Use when the traveler wants flights for known dates: one way, round trip, flexible dates, several airports, or multi-city. Give origin, destination and depart_date (return_date for a round trip), or pass their own words in query and leave unknown fields empty (nothing is guessed), or legs for multi-city. Returns priced itineraries cheapest first, itinerary_ids for track_flight and search_return_flights, and a search_url. Not for 'when is it cheapest' (price_calendar) or flexible months (add_flight_bucket_list).

Use after search_flights when the traveler wants a specific return, or the next leg of a multi-city trip (once per remaining leg). Takes an outbound itinerary_id; returns complete itineraries with the trip total, needs_leg false once the trip is whole. Filters apply to the leg being chosen. Not needed for an outbound watch.

Use for 'when is it cheapest to fly' on a route: the cheapest fare per departure day across about two months. Then search_flights on the chosen day for bookable itineraries. Not for a specific date.

Use to start price alerts on an itinerary from a search, after the traveler confirms. One way: any itinerary_id from search_flights. Round trip: an outbound itinerary_id from search_flights watches that outbound with its cheapest return; a complete itinerary_id from search_return_flights tracks that exact pairing. Multi-city: a complete itinerary_id. Alerts go to the account's channels on a new low; alert_rule any hears every move; target_price_usd sets a bar.

Use to see the flight price alerts on the signed-in account: route, dates, cabin, alert settings, each itinerary's current price against the price when tracking began, and the search_key and fid that stop_tracking_flight and update_flight_tracking take.

Use to stop price alerts for a tracked route (search_key from list_tracked_flights), or one itinerary in it (fid). Cannot be undone; confirm first.

Use for 'any deals right now?': the freshest price-drop alerts SlickTrip actually sent, by category (flights, hotels, seats, flexible routes). Not a search; no account needed.

Use when unsure of an airport or city code before searching. Matches a place name or code and returns the code to pass as origin or destination, whether it is one airport or all airports in a city, and the airports a city code covers. Not needed for well-known codes like JFK or LHR.

Use when the traveler wants to book flights they have chosen: the sellers offering that exact itinerary (airline direct and agencies), each with its price and a link that opens its checkout on the seller's site. Takes a complete itinerary_id: one-way from search_flights, round trip from search_return_flights. Not for an outbound alone (choose a return first) and not a price watch (track_flight).

Use when the traveler wants to book a hotel from search_hotels: every seller quoting it for those dates (the hotel itself and booking sites), each with the stay total and a link that opens its checkout on the seller's site. Takes the search_key and hotel_id from search_hotels. Not a price watch (track_hotel).

Use when the traveler asks for the details, more information, photos, rooms or description of one hotel from search_hotels: description, photos, guest rating, amenities, the sellers' stay totals, the rooms, check-in and check-out times. Takes the search_key and hotel_id from search_hotels. Not for prices across dates (hotel_price_calendar). Booking links are hotel_booking_options; call that only when they say book.

Use when the traveler wants to know which flights operate a route on a date, or needs a flight number for seat_availability or track_seats: departure and arrival times, carrier, aircraft, stops. No fares. Not for prices (search_flights) and not for a whole month (price_calendar).

Use when the traveler pastes a slicktrip.com/share link: the shared itinerary or bucket list and its current price, so they can start their own watch on it. Takes the link or its code. Not for making a link (share_link).

Use when the traveler asks who flies a route, or before filtering by airline: the carriers on the route, nonstop ones first, with the codes the airlines filters take. Not a fare search.

Use when the traveler wants a place to stay for known dates. Returns hotels cheapest first with star class, guest rating, per-night and whole-stay price, hotel_ids and a search_key for track_hotel and hotel_price_calendar, and a search_url. Filters match the site: price, stars, guest rating, property kinds, amenities, free cancellation, hotels or vacation rentals, sort. Not for flexible months (add_hotel_bucket_list).

Use to start price alerts on one hotel from search_hotels for those dates, after the traveler confirms. Alerts go to the account's channels when the price drops.

Use to see the hotel price alerts on the signed-in account: stay dates, guests, each hotel's current price against the price when tracking began, and the tracking_id and hotel_id the update and stop tools take.

Use to stop price alerts for a tracked stay (tracking_id from list_tracked_hotels), or one hotel in it (hotel_id). Cannot be undone; confirm first.

Use to see which seats are open right now on one flight (signed-in account: the live seat map is a paid lookup): open seat numbers by row, counts of window, aisle, middle and exit-row seats, and rows with two seats together. Needs the flight number, route and date. Then track_seats to be told when a seat opens. Not for prices.

Use to start seat alerts on one flight, after the traveler confirms: named seats, or every seat of a kind (window, aisle, middle, any), optionally only when N seats open together in a row. Alerts go to the account's channels when a watched seat opens.

Use to see the seat alerts on the signed-in account: flight, departure, cabin, the seats watched and which are open now, and the tracking_key the update and stop tools take.

Use to stop the seat alert on one flight (tracking_key from list_tracked_seats). Cannot be undone; confirm first.

Use for flexible-date watches ('tell me when New York to Tokyo drops under $700 this winter'): SlickTrip keeps searching the chosen months or date window and alerts when a fare clears the price bar. Returns a bucket_id. Confirm first. Not for fixed dates (search_flights, then track_flight).

Use for flexible-date hotel watches on a place or one named hotel: SlickTrip keeps searching stays of the given length across the chosen months or date window and alerts when a stay clears the per-night bar. Returns a bucket_id. Confirm first. Not for fixed dates (search_hotels, then track_hotel).

Use to see the flight and hotel bucket lists on the signed-in account, each with its settings, the best deals found so far, and the bucket_id that update_bucket_list, remove_bucket_list and share_link take.

Use to stop a bucket list (bucket_id from list_bucket_lists). Cannot be undone; confirm first.

Use for 'when is this hotel cheapest' (signed-in account): one hotel's nightly price by check-in date across a span of months. Needs a hotel_id from search_hotels. Then search_hotels with the chosen dates to track it.

Use when the traveler wants to continue on slicktrip.com, or the account is not connected: builds a link that lands them fully configured without running a search (a flights search with a track_url that starts tracking on arrival, a bucket list that saves on arrival, a hotel search, or the seat tracker).

Use to change how a tracked route alerts: the alert rule, a target price, or the email and text channels. Only the fields given change. Confirm first.

Use to change how a tracked stay alerts: the alert rule, a target price, the email and text channels, or its name. Only the fields given change. Confirm first.

Use to pause or resume a seat alert, or change its seats-together rule or channels. To watch different seats call track_seats again (it adds to the alert). Only the fields given change. Confirm first.

Use to edit a bucket list: the price bar, months or date window, nights, stops, airlines, preferred weekdays, name, guests, stars, or channels. Only the fields given change; a changed search resets the deals found so far. Confirm first.

Use before offering text alerts, or when the traveler asks about their account: name, member since, which alert channels work (text needs a phone verified on the site), the plan and its free limit, and how many fares, stays, seats and bucket lists are watched.

Use to change the display name, or the default alert channels (email, text) for new alerts, optionally applied to everything already watched. Phones are verified on the site, not here. Only the fields given change. Confirm first.

Use when the traveler wants to share a tracked route or a flight bucket list: a public slicktrip.com link, the same one the site's Share button makes, showing the itinerary and its price and nothing about the account. Made once and reused.
