WHAT IT DOES

What execute_promql_query does on AWS DocumentDB MCP Server

AI agents invoke execute_promql_query to trigger actions in AWS DocumentDB 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

Although the description is empty (lowering confidence slightly), the tool name clearly indicates execution of queries via PromQL. This falls under the Execute category because PromQL queries can trigger complex operations, aggregations, and side effects depending on the query arguments provided by an AI agent. An agent with this tool could execute arbitrary or malicious PromQL expressions.

From the tool's definition Tool name 'execute_promql_query' indicates execution of PromQL (Prometheus Query Language) queries. PromQL is a query language that can execute expressions against time-series databases.
