Use this when the user asks about call queues:
AI agents call find_queues 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 or lists call queue information from the 3CX phone system. It matches the Read category pattern of querying data with no side effects. The severity is low because queue information is non-sensitive operational metadata, and misuse would only allow an agent to view queue details without ability to reconfigure or disrupt service.
From the tool's definition Tool name 'find_queues' and description 'Use this when the user asks about call queues' indicate a query/search operation that retrieves information about call queue configuration and status without modifying any data.
Attacks that exploit this kind of access
Use this when the user asks about call queues:. 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 find_queues: 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.
find_queues 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 find_queues 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 find_queues. 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.
find_queues 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.
