Why start_wireless_listener needs a policy

Starting a wireless listener is a network operation that initiates external code execution (wireless packet capture daemon or similar tool) whose effects depend on runtime arguments and system state. While the description is empty, the tool name combined with server context strongly indicates Execute rather than passive Read.

From the tool's definition Tool name 'start_wireless_listener' on a pentester-focused MCP server; combined with server context mentioning 'reconnaissance' tools and 'Docker sandboxing for safe execution,' this indicates execution of wireless packet capture or network monitoring…

POLICY

How to control start_wireless_listener

PolicyLayer is an MCP gateway — it sits between your AI agents and Pentester-MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for start_wireless_listener:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "start_wireless_listener": {
      "limits": [
        {
          "counter": "start_wireless_listener_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

start_wireless_listener stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Pentester-MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about start_wireless_listener

What does the start_wireless_listener tool do? +

start_wireless_listener. It is categorised as a Execute tool in the Pentester-MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on start_wireless_listener? +

Register the Pentester- MCP server in PolicyLayer and add a rule for start_wireless_listener: 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 Pentester-MCP. Nothing to install.

What risk level is start_wireless_listener? +

start_wireless_listener is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit start_wireless_listener? +

Yes. Add a rate_limit block to the start_wireless_listener 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.

How do I block start_wireless_listener completely? +

Set action: deny in the PolicyLayer policy for start_wireless_listener. 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.

What MCP server provides start_wireless_listener? +

start_wireless_listener is provided by the Pentester- MCP server (halilkirazkaya/pentester-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Pentester-MCP tool call.

Start from Pentester-MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
