Get list of members (participants) of a workgroup
AI agents call bitrix_group_members 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 read-only retrieval operation that returns membership data. It has no side effects and does not modify data, execute code, delete information, or involve financial operations. While group membership lists could be considered sensitive information in some contexts, the act of listing members is fundamentally informational with minimal blast radius.
From the tool's definition Tool name 'bitrix_group_members' and description 'Get list of members (participants) of a workgroup' indicate a query operation that retrieves group membership information without modification.

bitrix_group_members is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the bitrix_group_members rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
