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.

//  Build the prompt's arguments (pass an empty object for a prompt that takes no arguments).  The
//  prompt name and its arguments come from the "prompts" array returned by ListPrompts.

//  Call the MCP prompts/get method for the named prompt.  The prompt result is placed in the
