What stop_impacket_sniff does on Pentester-MCP

AI agents invoke stop_impacket_sniff to trigger actions in Pentester-MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

High Risk

Why stop_impacket_sniff needs a policy

Terminating a running process is an Execute action—it triggers an external operation with effects that depend on which process instance is targeted. While not destructive in the sense of permanent data loss, process termination is a consequential system operation that could interrupt legitimate network monitoring or analysis workflows.

From the tool's definition Tool explicitly terminates a background process ('Terminates a background impacket-sniff process'). Process termination is a form of external operation execution that triggers system-level effects.

How to control stop_impacket_sniff

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 stop_impacket_sniff:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "stop_impacket_sniff": {
      "limits": [
        {
          "counter": "stop_impacket_sniff_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

stop_impacket_sniff 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.

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

Questions about stop_impacket_sniff

What does the stop_impacket_sniff tool do? +

Terminates a background impacket-sniff process. 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 stop_impacket_sniff? +

Register the Pentester- MCP server in PolicyLayer and add a rule for stop_impacket_sniff: 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 stop_impacket_sniff? +

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

Can I rate-limit stop_impacket_sniff? +

Yes. Add a rate_limit block to the stop_impacket_sniff 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 stop_impacket_sniff completely? +

Set action: deny in the PolicyLayer policy for stop_impacket_sniff. 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 stop_impacket_sniff? +

stop_impacket_sniff 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.
