List all events from YearAtAGlance calendar. Optionally filter by year and/or category.
AI agents call yaag_list_events to retrieve information from YearAtAGlance MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries calendar event data without side effects. It performs a read-only operation analogous to a SELECT query. The optional filtering parameters do not change its fundamental nature as a data retrieval operation. Severity is low because exposure of this tool poses minimal risk—an AI agent listing events has no ability to modify, delete, or trigger external actions.
From the tool's definition Tool name 'yaag_list_events' and description 'List all events from YearAtAGlance calendar' indicate data retrieval with optional filtering by year and/or category. No modification, deletion, or execution of external operations occurs.
