  @mcp.tool()
  async def config_list_discovered_resources(aws_region: str, resource_type: str) -> str:
      """
      List resource identifiers that AWS Config has discovered.
  
      Parameters:
        aws_region (str): The AWS region - use 'us-east-1' if not specified.
        resource_type (str): e.g. 'AWS::EC2::Instance'.
  
      Returns:
        JSON list of resourceIdentifier objects.
      """
      client = boto3.client('config', region_name=aws_region)
      paginator = client.get_paginator('list_discovered_resources')
      all_resources = []
      for page in paginator.paginate(resourceType=resource_type):
          all_resources.extend(page.get('resourceIdentifiers', []))
      return json.dumps(all_resources, indent=2)
