Xbase++ Requires Chilkat v11.6.0+

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.

Background. This exposes the full protocol-level response for inspection or debugging after any MCP request.
