🔐 Security and Permissions - Least Privileges

The MCP tools require specific AWS permissions to function.

• Create a read-only IAM role - Restricts LLM agents from modifying AWS resources. This prevents unintended create, update, or delete actions.
• Enable CloudTrail - Tracks API activity across your AWS account for security monitoring.
• Follow least-privilege principles - Grant only essential read permissions (Describe*, List*, Get*) for required services.

The below creates an IAM policy with for list, read and describe actions only:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "cost-optimization-hub:ListEnrollmentStatuses",
        "cost-optimization-hub:ListRecommendations",
        "cost-optimization-hub:GetRecommendation", 
        "cost-optimization-hub:ListRecommendationSummaries",
        "ce:GetCostAndUsage",
        "ce:GetCostForecast",
        "compute-optimizer:GetEC2InstanceRecommendations",
        "compute-optimizer:GetEBSVolumeRecommendations",
        "compute-optimizer:GetLambdaFunctionRecommendations",
        "ec2:DescribeInstances",
        "ec2:DescribeVolumes",

🔍 Troubleshooting

Common Issues

1. Cost Optimization Hub Not Working

   python3 diagnose_cost_optimization_hub_v2.py

   • Ensure resources have been running for at least 14 days
   • Verify CloudWatch metrics are enabled
   • Check that you're analyzing the correct region

3. Permission Errors

   • Verify IAM permissions are correctly applied
   • Check AWS credentials configuration
   • Ensure Cost Optimization Hub is enabled in AWS Console

4. Import Errors

   # Check Python path and dependencies
   python3 -c "import boto3, mcp; print('Dependencies OK')"
   

Getting Help

• Check the for detailed usage instructions
• Run the diagnostic script: python3 diagnose_cost_optimization_hub_v2.py
• Run integration tests: python3 test_runbooks.py
