MCP server question

I am learning MCP Servers with Great explanation by Mumshad.
Regarding the flight booking MCP - the AI agent will crawl the available flights and stuff.
I have a question regarding payment.
Let’s say I ask an AI Agent to book a flight for me moreover the agent is talking to let’s say “MakeMyTrip”, now the details are with me like which flight, what timings and stuff.

Now, I would like to move ahead with the flight I have chosen. Will agent handle payments as well? If yes, how?

Do we need to enter card details and stuff?

Looking for an explanation.

For the agent to handle ticket purchases, you’d need an additional MCP service installed to handle that; otherwise, the underlying LLM won’t really know how to do that task. Luckily, MCP makes the agent extensible.
