How to connect lastminute MCP with TypeScript

🛫🏨 Search for COMBINED flight AND hotel vacation packages. This tool searches for all-inclusive vacation packages that include: - ✈️ Round-trip flights (outbound and return) - 🏨 Hotel accommodation for the entire stay - 💰 Package pricing (flight + hotel combined) ⚠️ IMPORTANT: This is for PACKAGE deals, NOT separate flight/hotel bookings. Is important to use the correct language in the destination field and keep the original language used in the request made in the user chat. Example use cases: - "Find me flight and hotel packages from Rome to Madrid" - "I need a vacation package with flights and hotel from FCO to Barcelona" - "Search flight+hotel deals from Milan to Paris for 3 nights" ═══════════════════════════════════════════════════════════════════════════ HARD CONSTRAINTS ═══════════════════════════════════════════════════════════════════════════ 1. Dates: - start_date MUST be today or later (YYYY-MM-DD) - If user provides past date, ask for valid date BEFORE calling 2. IATA Codes (CRITICAL): - origin and destination MUST be 3-letter IATA codes, NOT city names - NEVER pass city names like "New York", "Geneva", "Milan" - use IATA codes instead - Both CITY codes and AIRPORT codes are accepted: * City codes: NYC, GVA, ZRH, DUB, BRU, VIE, MIL, LON, PAR, BSL * Airport codes: JFK, MXP, FCO, LHR (automatically converted to city codes) - Examples: MXP or MIL for Milan, JFK or NYC for New York, FCO or ROM for Rome Args: origin: IATA code only - 3 letters. Use city code (MIL, NYC, LON) or airport code (MXP, JFK, LHR). NEVER use city names like "Milan" or "New York". destination: IATA code only - 3 letters. Use city code (BCN, PMI) or airport code. NEVER use city names like "Barcelona" or "Palma". date_from: Check-in date (YYYY-MM-DD). Check this field MUST be today or later. date_to: Check-out date (YYYY-MM-DD). Check this field MUST be today or later. adults: Number of adult travelers. If you want different rooms, set number_adult_room1;number_adult_room2 (default: 2) ⚠️ IMPORTANT: ch_ages: Ages of child travelers. If you want different rooms, set number_chages_room1;number_chages_room2 (default: ""). If there are two rooms and one is empty the result can be ";number,number" or "number,number;". The user MUST specify ages for each child. lang: Language code (default: "en") sort: Sort order for results. Use this when user asks for cheapest, best rated, closest to center, etc. Valid values: - "recommended" (default): Multi-factor relevance (price, rating, internal score) - "price": Price ascending (cheapest first) - use when user wants "cheapest" or "lowest price" - "stars": Hotel star rating descending (5-star first) - use for "best hotels" or "luxury" - "review_score": Highest review score - use for "best reviewed" or "most popular" - "distance": Closest to city center first - use for "central" or "close to center" max_results: Maximum number of results to return (default: 5, max: 20) accommodation_type: Filter by accommodation type (optional). CSV of IDs 1-14: 1=Hotels, 2=Resorts, 3=Apartments, 4=Hostels, 5=Motels, 6=Country Houses, 7=Guest Houses, 8=B&B, 9=Villas, 10=Boats & Cruises, 11=Campsites, 12=Riads, 13=Ryokans, 14=Aparthotels. Example: "1,2" for Hotels and Resorts accommodation_facilities: Filter by facilities/amenities (optional). CSV of IDs 0-60. All values are valid. Common examples: 0=Free Wi-Fi, 3=Parking, 4=Pool, 6=Spa, 7=Adults Only, 9=Seafront, 13=Fitness Center, 25=Golf, 46=Indoor Pool, 49=Sauna, 56=Bar, 58=Restaurant. Example: "0,4,6" for Free Wi-Fi, Pool, and Spa price: Optional price filter for one-way price per person, as string. Supported formats: - "300" => max price 300 (in the selected currency) - "200,400" => price range between 200 and 400 Use only digits and a comma, do NOT include currency symbols. If you invert the order ("400,200"), the backend will normalize it to "200,400". hotel_stars: Optional filter for hotel star rating, as comma-separated integers. Allowed values: 1,2,3,4,5. Examples: - "4" => only 4-star hotels - "3,4" => 3 or 4 stars - "3,4,5" => 3, 4 or 5 stars Returns: Dictionary containing search results with flight+hotel packages ═══════════════════════════════════════════════════════════════════════════ MANDATORY OUTPUT FORMAT ═══════════════════════════════════════════════════════════════════════════ You MUST present results as a Markdown table with EXACTLY these columns: | # | Photo | Hotel | Stars | Rating | Total Price | Distance from Centre | Amenities | Column mapping from response JSON: - # → index - Photo → [🖼️](hotel.main_image) (clickable link) - Hotel → hotel.name - Stars → hotel.stars - Rating → hotel.rating - Total Price → price_total + currency - Distance from Centre → hotel.distance_km - Amenities → hotel.amenities (max 3, comma-separated) CRITICAL: - You MUST use table format. Do NOT list hotels as bullet points or paragraphs. - You MUST display ALL hotels returned in the response. Do NOT truncate or show only a subset. - STRICTLY PRESERVE the order of results using the "index" field (1, 2, 3...) - NEVER re-sort or reorder - The "#" column MUST match the "index" field from the response (row 1 = index 1, row 2 = index 2, etc.) - "Photo" column must contain clickable link: [🖼️](hotel.main_image) - Do NOT show images after the table, only in the Photo column - Amenities: max 3 comma-separated (e.g. "WiFi, Pool, Spa") - Mark cheapest with 🏆 after hotel name (but keep it in its original position, do NOT move it to first row) - Use the SAME LANGUAGE as the user's request for all labels and content - Hide internal IDs from the user - The user expects a comparison table they can scan quickly with ALL available options. Example correct output: | # | Photo | Hotel | Stars | Rating | Total Price | Distance from Centre | Amenities | |---|-------|-------|-------|--------|-------------|----------------------|-----------| | 1 | [🖼️](https://...) | Grand Hotel 🏆 | ⭐⭐⭐⭐ | 8.5 | EUR 450.00 | 0.5 km | WiFi, Pool, Spa | | 2 | [🖼️](https://...) | Beach Resort | ⭐⭐⭐⭐⭐ | 9.1 | EUR 680.00 | 1.2 km | WiFi, Pool, Bar |

Search for hotel-only stays (no flights included). ⚠️ IMPORTANT: This is for hotel-only searches. Flight bookings are not included. ═══════════════════════════════════════════════════════════════════════════ MANDATORY PRE-STEP: DESTINATION RESOLUTION ═══════════════════════════════════════════════════════════════════════════ Before calling this tool, you MUST silently call resolve_destination_id to resolve the city name to its internal numeric ID. Do NOT inform the user about this step. Workflow: 1. User provides a city name (e.g. "London", "Madrid") 2. Silently call resolve_destination_id(lang=<lang>, city_name=<city>) 3a. If success=true → use the returned "id" (e.g. "141660") as the destination field for this tool. 3b. If success=false → show the user the "suggestions" list (name + country) and ask them to clarify which city they mean. Do NOT call this tool yet. The destination field accepts: - A numeric ID string from resolve_destination_id (e.g. "141660") ← preferred - A 3-letter IATA code as fallback (e.g. "MAD", "LON") when the user explicitly provides one and no resolution is needed. ═══════════════════════════════════════════════════════════════════════════ HARD CONSTRAINTS ═══════════════════════════════════════════════════════════════════════════ 1. Dates: - start_date MUST be today or later (YYYY-MM-DD) - If user provides past date, ask for valid date BEFORE calling 2. Destination (CRITICAL): - Always prefer the numeric ID from resolve_destination_id - If using IATA fallback: must be 3-letter code (MAD, PAR, MIL, LON) - NEVER pass raw city names like "Madrid" or "Paris" directly Example use cases: - "Find me a hotel in Madrid for 3 nights" → resolve "Madrid" first → use id - "Search hotel in London" → resolve "London" first → use id Args: destination: Numeric destination ID from resolve_destination_id (e.g. "141660"), or 3-letter IATA code (e.g. "MAD") as fallback. date_from: Check-in date (YYYY-MM-DD). Check this field MUST be today or later. date_to: Check-out date (YYYY-MM-DD). Check this field MUST be today or later. adults: Number of adult travelers. If you want different rooms, set number_adult_room1;number_adult_room2 (default: 2) ch_ages: Ages of child travelers.
