🔐 Required AWS Permissions

Your AWS credentials need these permissions. The MCP server uses your role to perform actions, hence proceed with least privilege access only. 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",
        "rds:DescribeDBInstances",
        "lambda:ListFunctions",
        "cloudwatch:GetMetricStatistics",
        "s3:ListBucket",
        "s3:ListObjectsV2",
        "support:DescribeTrustedAdvisorChecks",
        "support:DescribeTrustedAdvisorCheckResult",
        "pi:GetResourceMetrics"
      ],
      "Resource": "*"
    }
  ]
}
