Search for workgroups by name or filter criteria
AI agents call bitrix_group_search 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 is a straightforward search operation that queries existing data (workgroup listings) and returns results. It matches the 'Read' category definition of retrieving or querying data with no side effects. The low severity reflects that searching for group information poses minimal risk even if misused—worst case would be information disclosure of non-sensitive group metadata.
From the tool's definition Tool name 'bitrix_group_search' and description 'Search for workgroups by name or filter criteria' indicate a search/query operation that retrieves data without modification or side effects.
