Get the Last JSON-RPC Response from an MCP Server

Demonstrates Mcp.GetLastJsonData, which returns the complete JSON-RPC response envelope (the jsonrpc, id, and result members) from the most recent request into a JsonObject.

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