List calendar events by date range. Call before creating to avoid duplicates.
AI agents call get_calendar_events to retrieve information from CoupleHub MCP Server 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 calendar event data within a specified date range. It performs no modifications, deletions, or external actions—purely informational retrieval. The suggestion to call it before creating events confirms its role as a read-only lookup utility. Severity is low because misuse would only expose shared calendar data, which is sensitive but not destructive or financial in nature.
From the tool's definition Tool name 'get_calendar_events' and description 'List calendar events by date range' indicate a retrieval operation with no side effects.
