Get a Prompt from an MCP Server

See more MCP Client Examples

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.

use chilkat();

$success = 0;

$mcp = chilkat::CkMcp->new();

#  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 == 0) {
    print $mcp->lastErrorText() . "\r\n";
    exit;
}

#  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.
$args = chilkat::CkJsonObject->new();
$args->UpdateString("topic","azure-storage");

#  Call the MCP prompts/get method for the named prompt.  The prompt result is placed in the
#  JsonObject.
$json = chilkat::CkJsonObject->new();
$success = $mcp->GetPrompt("example-prompt",$args,$json);
if ($success == 0) {
    print $mcp->lastErrorText() . "\r\n";
    exit;
}

$json->put_EmitCompact(0);
print $json->emit() . "\r\n";
