Get description of all available department fields
AI agents call bitrix_department_fields 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 descriptive metadata about department fields without modifying, deleting, or executing any actions. It has no side effects and poses minimal security risk—an attacker gaining access could only discover the structure of department fields, not access sensitive data itself or cause irreversible harm. Severity is low because the blast radius is confined to information disclosure of schema metadata.
