AI agents call list_log_parsing_rules to retrieve information from Newrelic without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns existing log parsing rule configurations. It performs a read-only operation that retrieves information without creating, modifying, deleting, or executing any actions. The blast radius is minimal—an agent listing existing rules cannot cause data loss or unwanted system changes.
From the tool's definition Tool name 'list_log_parsing_rules' and description 'List all log parsing rules for an account' indicate data retrieval with no modification or side effects.
