Real travel data, charted into a plan
No twenty tabs. Search once; Marco composes flights, stays and experiences into a coherent itinerary and budget.
Aggregated search
Live flights (Duffel), hotels (LiteAPI) and experiences in one place. Real prices, times and names, never invented.
Ask Marco, your agent
An AI travel agent that runs the searches for you and returns a day-by-day itinerary with a clear budget summary.
Local MCP server
Marco runs a local MCP endpoint, so Claude, ChatGPT, Cursor and friends can search travel through the app too.

Marco doesn't lock you to one model. Pick how you want the agent to run.
