Get the Last JSON-RPC Response from an MCP Server

See more MCP Client Examples

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.

<?php

use Chilkat2\JsonObject;
use Chilkat2\Mcp;

$mcp = new Mcp();

// 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.
try {
    $mcp->Connect('https://learn.microsoft.com/api/mcp');

    // Perform an MCP request.
    $toolsResult = new JsonObject();
    $mcp->ListTools($toolsResult);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

// Get the complete JSON-RPC response envelope (the jsonrpc, id, and result members) from the most
// recent request.
$json = new JsonObject();
$mcp->GetLastJsonData($json);

$json->EmitCompact = false;
echo $json->Emit(), "\n";
