Workgroup management. Actions: - list: List all workgroups - get: Get group by ID (requires groupId) - members: Get group members (requires groupId) - my: Get current user
AI agents call bitrix_group 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.
The bitrix_group tool performs data retrieval operations only: listing workgroups, fetching group details by ID, retrieving group member lists, and getting current user information. These are standard read operations with no capability to create, modify, delete, or execute code. The blast radius of misuse is minimal—limited to unauthorized disclosure of organizational structure and membership data.
From the tool's definition Tool description explicitly states actions are 'list', 'get', 'members', and 'my' — all read-only operations that retrieve workgroup and membership information without modification or side effects.
Attacks that exploit this kind of access
Workgroup management. Actions: - list: List all workgroups - get: Get group by ID (requires groupId) - members: Get group members (requires groupId) - my: Get current user. 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_group: 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_group 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 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_group. 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_group 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.
bitrix_group is one line of Email MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
