Key features of McpClientServerExample

Client uses ModelContextProtocol.Client to communicate with the server.
Supports OpenAI GPT models for conversation and tool calling.
Server uses ModelContextProtocol.Server and communicates via standard input/output.
Provides built-in tools: Echo (returns user input) and ReverseEcho (returns reversed input).

Use cases of McpClientServerExample
