WHAT IT DOES

What manage_aws_emr_ec2_steps does on AWS IoT SiteWise MCP Server

AI agents invoke manage_aws_emr_ec2_steps to trigger actions in AWS IoT SiteWise MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why manage_aws_emr_ec2_steps needs a policy

The tool name suggests it manages EMR (Elastic MapReduce) steps on EC2 instances, which typically involves submitting and executing jobs/scripts on cloud infrastructure. 'Manage' can imply create, modify, or cancel operations. However, the description is empty, which significantly lowers confidence. Given the AWS EMR context, this likely triggers execution of distributed computing jobs.

From the tool's definition Tool name: 'manage_aws_emr_ec2_steps' — implies managing (submitting, running, cancelling) steps on AWS EMR EC2 clusters
