Get list of workgroups that the current user (webhook owner) belongs to
AI agents call bitrix_group_my 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 queries and returns data about workgroup membership for the authenticated user. It performs no modifications, deletions, code execution, or financial operations. The information returned could inform other actions, but the tool itself is purely informational.
From the tool's definition Tool description states 'Get list of workgroups' — a retrieval operation with no side effects. Verb 'Get' and action 'list' are characteristic of Read category tools.

bitrix_group_my 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_my 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.
