Get a single event by ID
AI agents call get_event to retrieve information from Google Calendar MCP Server 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 by ID with no side effects. It does not create, modify, delete, or execute any actions. This is a simple data retrieval operation, the lowest-risk category. Severity is low because accessing calendar event metadata poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'get_event' and description 'Get a single event by ID' indicate retrieval of a single calendar event without modification. This is a straightforward read operation that queries data.
