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: Boolean;
mcp: HCkMcp;
args: HCkJsonObject;
json: HCkJsonObject;

begin
success := False;

mcp := CkMcp_Create();

//  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 := CkMcp_Connect(mcp,'https://learn.microsoft.com/api/mcp');
if (success = False) then
  begin
    Memo1.Lines.Add(CkMcp__lastErrorText(mcp));
    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 := CkJsonObject_Create();
CkJsonObject_UpdateString(args,'topic','azure-storage');

//  Call the MCP prompts/get method for the named prompt.  The prompt result is placed in the
//  JsonObject.
json := CkJsonObject_Create();
success := CkMcp_GetPrompt(mcp,'example-prompt',args,json);
if (success = False) then
  begin
    Memo1.Lines.Add(CkMcp__lastErrorText(mcp));
    Exit;
  end;

CkJsonObject_putEmitCompact(json,False);
Memo1.Lines.Add(CkJsonObject__emit(json));
//  JSON parsing code for this result can be generated at Chilkat's online tool:
