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.

//  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 == false) {
    print $mcp->lastErrorText() . "\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 = new CkJsonObject();
$args->UpdateString('topic','azure-storage');

//  Call the MCP prompts/get method for the named prompt.  The prompt result is placed in the
//  JsonObject.
