The Travel Data Layer for AI Agents
RouteStack.ai gives LLM-powered applications real-time access to live travel inventory – hotels, flights, car hire, vacation rentals, and activities, via Model Context Protocol (MCP) servers.
const client = new RouteStackClient({
apiKey: "rs_live_••••••••",
transport: "mcp"
});
// Your agent queries live inventory
const results = await client.hotels.search({
destination: "Barcelona",
checkIn: "2025-06-14",
guests: 2
});
// Returns real availability + deep-link
→ 3,200+ live results · booking_url ✓
The Problem
AI agents can plan a trip.
They can't book one.
AI is transforming how people search and shop for travel. But when a user asks an AI agent to find a flight, check hotel availability, or book a car, the agent hits a wall.
There's no reliable, real-time data layer connecting LLMs to live travel inventory.
RouteStack solves that.
Find me a flight to Tokyo
Agent request → no live data source
Check hotel availability in Rome
Agent request → no real-time inventory
Book a car hire at Heathrow
Agent request → no booking flow
Any travel query, via RouteStack
Agent request → no live data source

Infrastructure
The infrastructure was already running.
RouteStack isn't a startup pitch. It's a new interface on top of infrastructure CTS has been building for nearly 30 years — supplier relationships, availability engines, deep-link checkout flows, and white-label capability that's already live for partners around the world.
The MCP layer is new. Everything underneath it has been running in production for years.
