WHAT IT DOES

What execute_cwl_insights_batch does on AWS Labs MySQL MCP Server

WHY IT NEEDS A POLICY

Why execute_cwl_insights_batch needs a policy

This tool executes batch operations on CloudWatch Logs, which can run queries whose effects depend on the query arguments provided by the AI agent. While primarily a read operation on logs, the execution of batch queries without explicit description creates risk if an agent could craft queries that consume excessive resources or extract sensitive data at scale.

From the tool's definition Tool name 'execute_cwl_insights_batch' indicates execution of CloudWatch Logs Insights queries in batch mode. The 'execute' verb combined with 'batch' operations on AWS CloudWatch Logs suggests running potentially arbitrary queries.
