IAM Role Setup

The CloudFormation stack in Setup Instructions automates the IAM role setup for you. If you want to manually execute it, please follow the instructions below:

IAM Role Setup for MCP Server

To access the SMUS Managed MCP server, an IAM role is required with the following inline policy:

{
    "Version": "2012-10-17",		 	 	 
    "Statement": [
        {
            "Sid": "allowUseDataProcessingMcpServer",
            "Effect": "Allow",
            "Action": [
                "sagemaker-unified-studio-mcp:InvokeMcp",
                "sagemaker-unified-studio-mcp:CallReadOnlyTool",
                "sagemaker-unified-studio-mcp:CallPrivilegedTool"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

In the next steps, we will create a profile for this role. Whichever account assumes this role to obtain the credentials should be added to the assume role policy.

{
  "Version": "2012-10-17",		 	 	 
  "Statement": [
    {
      "Sid": "AllowAccountToAssumeRole",
      "Effect": "Allow",
      "Principal": { "AWS": "arn:aws:iam::<accountId>:root" },
      "Action": "sts:AssumeRole"
    }
  ]
}

KMS Permissions - CloudWatch Logs

If the CloudWatch Logs are encrypted with a CMK, add the following policy so the service can read the EMR-Serverless application logs.

{
    "Effect": "Allow",
    "Action": [
        "kms:Decrypt",
        "kms:DescribeKey"
    ],
    "Resource": "arn:aws:kms:<region>:<account-id>:key/<cw-logs-cmk-id>"
}
