列出所有活跃的会话
AI agents call list_sessions to retrieve information from WeChat Article Reader MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only query of session metadata. It simply lists or enumerates active sessions, which has no side effects and does not alter system state. This is a passive information retrieval operation, making it a Read category tool. Severity is low because listing sessions poses minimal risk; it may expose session identifiers but does not enable direct unauthorized actions without additional tools.
From the tool's definition Tool name: list_sessions. Description (translated): 'List all active sessions.' This retrieves information about existing sessions without modifying, deleting, or executing any operations.
