Quick Start

1. Install dependencies:

   uv install fastmcp
   

2. Run the server:

   uv run python server.py
   

3. Run the client (in another terminal):

   uv run python client.py
   

What it does

• Server: Provides a book_doctor_appointment tool that collects user info step-by-step
• Client: Interactive appointment booking with smart input validation and retry logic

The client handles input validation on the client side and only re-prompts for invalid inputs, not the entire flow.
