Retrieve a list of call queues
AI agents call get_queues to retrieve information from VoIPBin MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves information about existing call queues. It performs no modifications, deletions, or external actions. The use of 'Retrieve' in the description explicitly indicates a read-only operation.
From the tool's definition Tool name 'get_queues' and description 'Retrieve a list of call queues' indicate a data retrieval operation with no side effects.
Attacks that exploit this kind of access
Retrieve a list of call queues. It is categorised as a Read tool in the VoIPBin MCP Server MCP Server, which means it retrieves data without modifying state.
Register the VoIPBin MCP Server MCP server in PolicyLayer and add a rule for get_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 VoIPBin MCP Server. Nothing to install.
get_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 get_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 get_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.
get_queues is provided by the VoIPBin MCP Server MCP server (nrjchnd/voipbin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
