Demonstrates Mcp.ReadResource, which calls the MCP resources/read method for a resource identified by URI and places the contents into a JsonObject.

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

#import <CkoMcp.h>
#import <CkoJsonObject.h>

BOOL success = NO;

CkoMcp *mcp = [[CkoMcp alloc] init];

//  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 == NO) {
    NSLog(@"%@",mcp.LastErrorText);
    return;
}

//  Read a specific resource by its URI.  A resource URI is obtained from the "resources" array
//  returned by ListResources.  The resource contents are placed in the JsonObject.
CkoJsonObject *json = [[CkoJsonObject alloc] init];
