获取登录状态，登陆完成返回1,没有登陆完成返回0
AI agents call get-login-status to retrieve information from zhihu MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool purely retrieves the current authentication status without side effects. It performs a simple state query comparable to checking a session or user status, which is a read-only operation. The return value (0 or 1) is merely informational and does not trigger any actions, modifications, or destructive operations.
From the tool's definition Tool name 'get-login-status' and description indicating it returns login state (1 for logged in, 0 for not logged in) with no modification of data or execution of external operations.
