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.

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

set mcp = CreateObject("Chilkat.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.
success = mcp.Connect("https://learn.microsoft.com/api/mcp")
If (success = 0) Then
    outFile.WriteLine(mcp.LastErrorText)
    WScript.Quit
End If

'  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.
set args = CreateObject("Chilkat.JsonObject")
success = args.UpdateString("topic","azure-storage")

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

If (success = 0) Then
    outFile.WriteLine(mcp.LastErrorText)

End If
