Search for specific events in the academic calendar
AI agents call search_calendar_events to retrieve information from OSU MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a search/query operation on academic calendar data, which is a read-only retrieval action. It has no side effects, does not create, modify, delete, or execute anything. The low severity reflects that calendar data is typically non-sensitive and widely available to university community members. Confidence is high because the description clearly indicates a search/retrieval function.
From the tool's definition Tool name 'search_calendar_events' and description 'Search for specific events in the academic calendar' indicate a query operation that retrieves event information without modifying or executing operations.
