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.

    //  Connect to a public MCP (Model Context Protocol) server over its Streamable HTTP endpoint.  The
    //  Microsoft Learn MCP server is public and requires no authentication.
    success = mcp.Connect("https://learn.microsoft.com/api/mcp");
    if (success == false) {
        std::cout << mcp.lastErrorText() << "\r\n";
        return;
    }

    //  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.
    CkJsonObject args;
    args.UpdateString("topic","azure-storage");

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