获取当前使用的SMTP配置（从环境变量读取）
AI agents call get_current_config to retrieve information from Email Sender 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 returns configuration data without making any changes, triggering external operations, or affecting system state. It is purely informational. While SMTP credentials could be sensitive, the tool itself performs no write, execute, destructive, or financial operations.
From the tool's definition Tool name 'get_current_config' and description 'retrieves current SMTP configuration from environment variables' indicate a read-only operation that queries existing configuration without modification.
