System utilities. Actions: - test_connection: Test Bitrix24 API connection - get_users: Get multiple users by IDs (requires userIds)
AI agents call bitrix_system 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.
Both actions are read-only operations. test_connection is a diagnostic probe and get_users fetches user data without side effects. This falls squarely into the Read category with low severity since user enumeration has minimal blast radius in most contexts.
From the tool's definition Tool actions are 'test_connection' (diagnostic, no data retrieval) and 'get_users' which retrieves user information by IDs. No modification, deletion, execution, or financial operations are performed.

System utilities. Actions: - test_connection: Test Bitrix24 API connection - get_users: Get multiple users by IDs (requires userIds). It is categorised as a Read tool in the Email MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Email MCP Server MCP server in PolicyLayer and add a rule for bitrix_system: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Email MCP Server. Nothing to install.
bitrix_system 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_system 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.
Set action: deny in the PolicyLayer policy for bitrix_system. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
bitrix_system is provided by the Email MCP Server MCP server (sventern/mcp_email). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
