fetch_cloudwatch_logs_for_service
AI agents call fetch_cloudwatch_logs_for_service to retrieve information from AWS_CloudGuardMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
CloudWatch logs can contain sensitive information (credentials, PII, business logic details, error messages revealing infrastructure), making unauthorized access a medium-severity risk. However, the operation itself is non-destructive and non-executable. Severity is elevated from 'low' due to the sensitive nature of log data that could be exposed to a misbehaving agent.
