List all flows in your VoIPbin account.
AI agents call list_flows 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 retrieves and lists existing flow configurations from the VoIPbin account without creating, modifying, or deleting any data. It is a pure read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'list_flows' and description 'List all flows in your VoIPbin account' indicate a data retrieval operation with no side effects.
Attacks that exploit this kind of access
List all flows in your VoIPbin account. 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 list_flows: 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.
list_flows 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_flows 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_flows. 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_flows is provided by the VoIPbin MCP Server MCP server (voipbin/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
