检查时间段的可用性
AI agents call check_availability to retrieve information from MCP Commute Assistant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool checks/queries availability status for time periods, which is a read-only operation with no side effects. It fits the Read category as it retrieves information without creating, modifying, or deleting data. The low severity reflects minimal risk if misused by an agent—it only exposes scheduling/availability visibility without enabling changes or external actions.
From the tool's definition Tool name 'check_availability' and description '检查时间段的可用性' (check availability of time period) indicate a query operation that retrieves availability information without modifying data.
