WHAT IT DOES

What policy_generation_start does on AWS IoT SiteWise MCP Server

AI agents invoke policy_generation_start 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 policy_generation_start needs a policy

Policy generation is an Execute action—it programmatically creates or initiates processes that produce downstream effects (policy creation, modification). While not destructive by itself, misconfiguration or malicious prompts could generate overly permissive policies. High severity due to IAM implications; confidence reduced to 0.75 due to empty description.

From the tool's definition Tool name 'policy_generation_start' combined with sibling tools like 'add_inline_policy' indicates policy automation/generation.
