Get full event details
AI agents call get_event to retrieve information from Microsoft MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves calendar event data without creating, modifying, or deleting anything. It has no side effects beyond reading information. While calendar events may contain sensitive information, the read-only nature and typical low impact of viewing event details (especially user's own events in a unified account context) places this in the Read category with low severity.
From the tool's definition Tool name 'get_event' and description 'Get full event details' indicate data retrieval without modification. This is a query operation that fetches event information.
