The MCP clients are still missing some key features to get to a fully autonomous booking, but we are getting there:

- With MCP Elicitations (https://modelcontextprotocol.io/specification/draft/client/e...) the server will be able to secure ask for complementary info like your name, passport and even your payments details.

- With mcp-ui (https://github.com/idosal/mcp-ui), supporting MCP Clients could allow the server to re-create the same booking flow UI that you find today on an aggregator's website
