List all sorting plans.
AI agents call imap_list_sorting_plans to retrieve information from Email MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates sorting plans without modifying, executing, or deleting data. It is a pure query operation with minimal blast radius if misused by an AI agent—an attacker could enumerate sorting configurations but could not alter email data or perform actions.
From the tool's definition Tool name 'imap_list_sorting_plans' and description 'List all sorting plans' indicate a retrieval operation with no side effects. The verb 'list' is explicitly enumerated as a Read category operation.
