Get a Prompt from an MCP Server

Demonstrates Mcp.GetPrompt, which calls the MCP prompts/get method for a named prompt, passing a JSON arguments object and receiving the prompt result.

Tip: Code to parse the returned JSON can be generated with Chilkat's online tool at https://tools.chilkat.io/jsonParse.
