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.

var
success: Integer;
mcp: TChilkatMcp;
args: TChilkatJsonObject;
json: TChilkatJsonObject;

begin
success := 0;

mcp := TChilkatMcp.Create(Self);

//  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
  begin
    Memo1.Lines.Add(mcp.LastErrorText);
    Exit;
  end;

//  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 := TChilkatJsonObject.Create(Self);
args.UpdateString('topic','azure-storage');

//  Call the MCP prompts/get method for the named prompt.  The prompt result is placed in the
//  JsonObject.
json := TChilkatJsonObject.Create(Self);
success := mcp.GetPrompt('example-prompt',args.ControlInterface,json.ControlInterface);
if (success = 0) then
  begin
    Memo1.Lines.Add(mcp.LastErrorText);
    Exit;
  end;

json.EmitCompact := 0;
Memo1.Lines.Add(json.Emit());
