Find upcoming events at parks
AI agents call getEvents to retrieve information from Nationalparks without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The action is purely informational (find/retrieve), which is the definition of a Read category tool. Severity is low because misuse would only return unwanted but harmless event data.
