Kiwi.com Flight Search

The Kiwi.com Flight Search MCP Server connects your AI assistant directly to Kiwi.com’s flight search engine.

The MCP server allows your AI to search for and book flights based on your specific travel requirements.

You can use it through Claude, Cursor, or other MCP-compatible clients to find flight options without switching applications.

Features

• ✈️ Search for one-way or round-trip flights
• 🌍 Find flights by city or airport codes
• 📅 Specify exact travel dates or use +/- 3 day flexibility
• 👨‍👩‍👧‍👦 Set passenger counts (adults, children, infants)
• 🛋️ Select cabin class (economy to first class)
• 🔗 Get direct booking links for selected flights

Use Cases

• Quick Vacation Planning: You’re thinking about a family trip. You can ask your AI, “Find round-trip flights for two adults and two kids from Vienna to London from August 3rd to 10th.” The server will return a list of suitable options with booking links.
• Last-Minute Business Travel: A sudden meeting comes up. You can tell your assistant, “I need a first-class, one-way ticket from Paris to Rome for tomorrow,” and get immediate results.
• Comparing Flexible Dates: If your travel dates aren’t fixed, you can check for better prices. For instance, ask, “Find the best price for a flight from New York to Lisbon next month with flexible dates.”
• Developer Integration Testing: If you’re building a custom AI agent, you can use this server to test and integrate flight search functionalities into your application without needing to build the backend logic yourself.

Usage

After installing the server through your preferred MCP client, you interact with it through natural language queries. The server exposes a single tool called search-flight that handles all flight search parameters.

The search-flight tool accepts these parameters:

• trip_type: “one-way” or “round-trip”
• origin: City name or airport code
• destination: City name or airport code
• departure_date: Date in YYYY-MM-DD format
• return_date: Required for round-trip flights
• adults: Number of adult passengers
• children: Number of child passengers
• infants: Number of infant passengers
• cabin_class: “economy”, “premium_economy”, “business”, or “first”
• flexibility: true/false for +/- 3 day date flexibility

You don’t need to manually construct these parameters. Instead, ask your AI assistant natural questions like “Find me business class flights from New York to London next Tuesday for two adults” or “Show economy flights from Paris to Tokyo with flexible dates in September.”

The AI will parse your request, call the search-flight tool with the appropriate parameters, and present you with flight options that include prices, airlines, times, and direct booking links.
