UBOS Asset Marketplace: Revolutionizing Travel with the Flight & Stay Search MCP Server

In the rapidly evolving landscape of AI and automation, the need for seamless integration between AI agents and real-world data sources has never been greater. At UBOS, we understand this imperative. That’s why we’re proud to feature the Flight & Stay Search MCP (Model Context Protocol) Server on our Asset Marketplace, a powerful tool designed to revolutionize how AI agents handle travel-related queries. This TypeScript implementation, leveraging the Duffel API, empowers developers to create sophisticated applications capable of searching for flights (one-way, round-trip, and multi-city) and accommodations with ease.

What is an MCP Server and Why Does It Matter?

Before diving deeper, let’s clarify the role of an MCP Server. An MCP (Model Context Protocol) Server acts as a crucial intermediary, standardizing how applications provide context to Large Language Models (LLMs). Think of it as a translator, enabling AI models to access and interact with external data sources, APIs, and tools. Without MCP servers, AI agents would be confined to the data they’re initially trained on, severely limiting their ability to provide real-time, accurate, and comprehensive information.

UBOS, as a full-stack AI Agent Development Platform, recognizes the pivotal role MCP servers play in unlocking the true potential of AI agents. Our platform is dedicated to bringing AI agent technology to every business department, enabling them to orchestrate AI agents, connect them with enterprise data, build custom AI agents with your own LLM models, and even create sophisticated Multi-Agent Systems. The Flight & Stay Search MCP Server perfectly exemplifies how MCPs can dramatically enhance the capabilities of AI agents in specific domains.

Use Cases: Unleashing the Power of the Flight & Stay Search MCP Server

The Flight & Stay Search MCP Server opens up a plethora of exciting use cases, transforming how businesses and individuals approach travel planning. Here are just a few examples:

• AI-Powered Travel Assistants: Imagine an AI assistant that can not only understand natural language requests like “Find me a flight from San Francisco to New York next week” but also proactively suggest optimal flight and hotel combinations based on your preferences and budget. This MCP server makes it possible.
• Dynamic Pricing Optimization: Travel agencies and airlines can leverage this MCP server to dynamically adjust pricing based on real-time demand, competitor pricing, and accommodation availability. AI agents can continuously monitor these factors and optimize pricing strategies to maximize revenue.
• Personalized Travel Recommendations: By integrating this MCP server with customer databases and preference profiles, businesses can deliver highly personalized travel recommendations. AI agents can analyze past travel history, preferred destinations, and budget constraints to suggest tailored flight and stay options.
• Automated Travel Booking: Streamline the travel booking process by automating tasks such as flight and hotel searches, itinerary creation, and reservation confirmations. AI agents can handle these tasks efficiently, freeing up human agents to focus on more complex customer inquiries.
• Corporate Travel Management: Companies can use this MCP server to build AI-powered travel management systems that automatically book flights and accommodations for employees based on pre-defined travel policies and budget constraints. This can significantly reduce travel expenses and improve efficiency.
• Integration with Chatbots: Enhance customer service by integrating the Flight & Stay Search MCP Server with chatbots. Customers can ask questions about flight availability, hotel options, and pricing directly within the chatbot interface, receiving instant and accurate responses.

Key Features: Diving Deep into the MCP Server’s Capabilities

The Flight & Stay Search MCP Server boasts a comprehensive set of features designed to empower developers and streamline travel-related AI applications. Here’s a closer look at some of its key functionalities:

• Flight Search: The core functionality enables searching for one-way, round-trip, and multi-city flights using the Duffel API. Specify departure and arrival airports, travel dates, number of passengers, and cabin class to refine your search. The integration with Duffel ensures access to a wide range of airlines and flight options.
• Detailed Flight Offer Information: Retrieve comprehensive details about specific flight offers, including flight times, aircraft type, baggage allowance, and fare rules. This allows users to make informed decisions and choose the best flight option for their needs. The get_offer_details tool provides this critical information.
• Cabin Class and Passenger Customization: Tailor flight searches by specifying cabin class (e.g., economy, business, first class) and the number of passengers traveling. This ensures that the search results align with the specific requirements of each traveler. The ability to specify passenger details is crucial for accurate pricing and availability.
• Connection Preferences: Filter flight searches based on connection preferences, such as the maximum number of layovers or preferred connection airports. This allows users to optimize their travel time and avoid undesirable layovers. This offers a layer of personalization and control.
• Departure and Arrival Time Windows: Narrow down flight searches by specifying preferred departure and arrival time windows. This is particularly useful for travelers with specific scheduling constraints. This allows users to prioritize convenience.
• Stay Search: Beyond flights, the MCP server facilitates searching for travel stays (hotels/accommodations) using the search_stays tool. Specify the destination, check-in and check-out dates, and number of guests to find suitable accommodation options.
• Guest Reviews: Access guest reviews for specific stays/hotels using the get_stay_reviews tool. This enables users to make informed decisions based on the experiences of other travelers. Reviews can significantly impact booking decisions, making this a valuable feature.
• Multi-City Flight Search: A specialized tool, search_multi_city, simplifies the process of searching for complex multi-city itineraries. This is ideal for travelers who want to visit multiple destinations in a single trip.

Technical Deep Dive: Setting Up and Using the MCP Server

The Flight & Stay Search MCP Server is built using TypeScript, a popular and robust programming language known for its scalability and maintainability. Setting up the server is a straightforward process:

1. Install Dependencies: Use npm install to install all necessary packages and libraries.
2. Build the Project: Compile the TypeScript code into JavaScript using npm run build.
3. Start the Server: Launch the server using npm start. This will typically start the server on a default port (e.g., port 3000).
4. Environment Variables: Configure the server by creating a .env file and setting the DUFFEL_API_KEY variable. You can obtain a test API key from Duffel to experiment with the functionality.

To publish this MCP to Smithery: bash npx @smithery/cli publish

To run the published MCP: bash npx @smithery/cli run @your-username/flights-mcp-ts --config “{“duffelApiKey”:“your_duffel_api_key”}”

Example Queries: Interacting with the MCP Server

The MCP server provides a user-friendly interface for querying flight and stay information. Here are some example queries:

• Flight Search: “Find flights from SFO to NYC on May 15, 2025”
• Round-Trip Flight Search: “Search for a round-trip flight from LAX to LHR departing June 10 and returning June 20”
• Business Class Flight Search: “Find business class flights from Tokyo to Paris for 2 adults”
• Flight Offer Details: “Get details for flight offer [offer_id]”
• Hotel Search: “Find hotels in London for 2 guests from 2025-06-10 to 2025-06-12”
• Hotel Reviews: “Get reviews for stay [hotel_id]”

These examples showcase the versatility of the MCP server and its ability to handle a wide range of travel-related requests. The server parses these natural language queries and translates them into API calls to the Duffel API, retrieving the relevant information and presenting it in a structured format.
