WHAT IT DOES

What execute_promql_query does on AWS IoT SiteWise MCP Server

AI agents invoke execute_promql_query 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 execute_promql_query needs a policy

Despite the empty description, the tool name strongly suggests this executes PromQL queries, which is a query execution operation that can trigger monitoring actions, retrieve sensitive metrics from AWS infrastructure, or interact with external systems. This falls under Execute rather than Read because 'execute' implies active execution of potentially complex operations whose effects depend on query arguments.

From the tool's definition Tool name 'execute_promql_query' indicates execution of PromQL (Prometheus Query Language) queries against monitoring infrastructure. The 'execute' verb combined with query execution capability indicates code/query execution.
