Use this when the user asks about ring groups (not queues). Ring groups ring multiple extensions simultaneously or in sequence. Returns: Id, Number, Name, Members, RingStrategy.
AI agents call list_ring_groups to retrieve information from 3CX MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries ring group configuration data without any side effects. It does not create, modify, delete, or execute operations. It is a straightforward read operation that provides visibility into the phone system's ring group setup, posing minimal security risk if misused by an AI agent.
From the tool's definition Tool returns information about ring groups: 'Returns: Id, Number, Name, Members, RingStrategy.' No parameters for modification or deletion are described. The verb 'list' and 'returns' indicate data retrieval only.
Attacks that exploit this kind of access
Use this when the user asks about ring groups (not queues). Ring groups ring multiple extensions simultaneously or in sequence. Returns: Id, Number, Name, Members, RingStrategy. It is categorised as a Read tool in the 3CX MCP Server MCP Server, which means it retrieves data without modifying state.
Register the 3CX MCP Server MCP server in PolicyLayer and add a rule for list_ring_groups: 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 3CX MCP Server. Nothing to install.
list_ring_groups 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 list_ring_groups 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 list_ring_groups. 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.
list_ring_groups is provided by the 3CX MCP Server MCP server (ssig-it/3cx-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
