var     
  lCallbackGetWeather : TMCPAction;
begin
 lCallbackGetWeather :=
       procedure(var Params: TJSONObject; out Result: TDMCPCallToolsResult; out Error: TDMCPCallToolsContent)
       var
         Location: string;
         EnableLog: Boolean;
         WeatherService: IWeatherService;
         WeatherData: string;
       begin
         try
            try
              // Extract parameters
              Location := Params.GetParam('location');
              EnableLog := Params.GetParam('EnableLog', trBool);

              // Validation of required parameters
              if Location.Trim = '' then
                raise Exception.Create('Location parameter is required');

              WeatherService := TMockWeatherService.Create;
              WeatherData := WeatherService.GetWeatherData(Location);


              if EnableLog then
                TDMCPServer.WriteToLog(Format('Weather data requested for %s', [Location]));

              // Assemble the result - There's no need to release it from memory; it's done automatically.
              Result := TDMCPCallToolsResult.Create;
              Result.Content.AddRange(TDMCPCallToolsContent.Create(ptText, WeatherData));

              Error := nil;
            finally
              Params.Free;
            end;
         except
            on E: Exception do
            begin
              // Handles exceptions. to MCPServers Defaults
              Error := TDMCPCallToolsContent.Create(ptText,
                'Weather service error: ' + E.Message);
              TDMCPServer.WriteToLog('Error in get_weather: ' + E.Message);
              Result := nil;
            end;

📋 Create and register your server informations

var     
   lDMCP: IDMCPServerRegister;
begin
   lDMCP := TDMCPServerRegister.New
      .SetLogs(True);  //Set Logs Request

    lDMCP
      .RegisterAction('get_weather', 'Get current weather information', lCallbackGetWeather)     
      .ServerInfo
      .SetServerName('DinosMCPServer')
      .SetVersion('0.1.0')        
        .Tools(TMCPServerTools.New
           .SetName('get_weather')
           .InputSchema
              .SetType(ptObject)
              .SetProperties('location', ptString)
              .SetProperties('Conditions', ptString)
              .SetProperties('EnableLog', ptBoolean)
              .SetRequired(['location'])
              .SetAdditionalProperties(False)
           .&End);
    lDMCP.Run;
end;
