OnMCPResponseTool Event

Delivers the result of a tools/call invocation.

Syntax

property OnMCPResponseTool: TsgcAI_MCP_Client_OnResponseToolEvent;
// TsgcAI_MCP_Client_OnResponseToolEvent = procedure(Sender: TObject; const aRequest: TsgcAI_MCP_Request_ToolsCall; const aResponse: TsgcAI_MCP_Response_ToolsCall) of object

Default Value

—

Remarks

Triggered when the server returns a reply to RequestTool. Inspect aResponse.Result.Content for the returned items (text, images, embedded resources) and aResponse.Result.IsError for tool-reported failures. The matching request is available in aRequest.Params.Name and aRequest.Params.Arguments so you can correlate concurrent tool calls.

Example

procedure TMainForm.MCPResponseTool(Sender: TObject;
  const aRequest: TsgcAI_MCP_Request_ToolsCall;
  const aResponse: TsgcAI_MCP_Response_ToolsCall);
begin
  if aResponse.Result.IsError then
    Log('Tool ' + aRequest.Params.Name + ' failed')
  else
    Log('Tool ' + aRequest.Params.Name + ' -> ' + aResponse.Write);
end;
