Implementation Reference
- src/server.ts:143-179 (handler)The handler function for the 'search_multi_city' tool. It constructs flight slices from the provided segments and creates an offer request using the DuffelClient with a 30-second timeout.async (params: MultiCityRequest) => { try { const slices = []; // Build slices from segments for (const segment of params.segments) { slices.push(flightClient.createSlice( segment.origin, segment.destination, segment.departureDate )); } // Create the offer request with a longer timeout for multi-city const response = await flightClient.createOfferRequest({ slices, cabin_class: params.cabinClass, adult_count: params.adults, max_connections: params.maxConnections, return_offers: true, supplier_timeout: 30000 // 30 seconds }); return { content: [ { type: 'text', text: JSON.stringify(response, null, 2) } ] }; } catch (error) { console.error(`Error searching multi-city flights: ${error}`); throw error; } }
- src/server.ts:140-180 (registration)Registration of the 'search_multi_city' tool on the MCP server, specifying the tool name, input schema, and handler function.server.tool( 'search_multi_city', multiCityRequestSchema.shape, async (params: MultiCityRequest) => { try { const slices = []; // Build slices from segments for (const segment of params.segments) { slices.push(flightClient.createSlice( segment.origin, segment.destination, segment.departureDate )); } // Create the offer request with a longer timeout for multi-city const response = await flightClient.createOfferRequest({ slices, cabin_class: params.cabinClass, adult_count: params.adults, max_connections: params.maxConnections, return_offers: true, supplier_timeout: 30000 // 30 seconds }); return { content: [ { type: 'text', text: JSON.stringify(response, null, 2) } ] }; } catch (error) { console.error(`Error searching multi-city flights: ${error}`); throw error; } } );
- src/models/flightSearch.ts:43-50 (schema)Zod schema defining the input parameters for the 'search_multi_city' tool, including segments, cabin class, adults, and max connections.export const multiCityRequestSchema = z.object({ segments: z.array(flightSegmentSchema).min(2).describe('Flight segments for multi-city trip'), cabinClass: z.enum(['economy', 'premium_economy', 'business', 'first']).describe('Cabin class'), adults: z.number().min(1).default(1).describe('Number of adult passengers'), maxConnections: z.number().optional().describe('Maximum number of connections') }); export type MultiCityRequest = z.infer<typeof multiCityRequestSchema>;
