search_reminders
AI agents call search_reminders to retrieve information from MCP Apple Reminders without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Search operations retrieve or query data without modifying it, fitting the Read category. Even though the description is empty, the tool name and server context make it clear this searches existing reminders rather than creating, executing, or destructing data. Severity is low because read access to personal reminders poses minimal risk compared to write or destructive operations.
From the tool's definition Tool name 'search_reminders' combined with server's 'search' capability in the description indicates data retrieval.
