Terminates a running mitm6 process using its Process ID (PID).
AI agents invoke stop_mitm6 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.
This tool executes an external operation (process termination) whose effects depend on the provided PID argument. While termination itself is not destructive to data, it triggers a system-level action that stops a running security testing tool. Misuse could disrupt legitimate security assessments or be chained with other attacks.
From the tool's definition Tool 'stop_mitm6' terminates a running mitm6 process. mitm6 is a penetration testing tool that performs Man-in-the-Middle attacks on IPv6 networks. The tool executes a process termination command based on a PID argument.
Documented attack patterns abuse exactly the kind of access stop_mitm6 gives an agent:
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_mitm6:
{
"version": "1",
"default": "deny",
"tools": {
"stop_mitm6": {
"limits": [
{
"counter": "stop_mitm6_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}stop_mitm6 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.
Free to start. No card required.
Terminates a running mitm6 process using its Process ID (PID). 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.
Register the Pentester- MCP server in PolicyLayer and add a rule for stop_mitm6: 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.
stop_mitm6 is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the stop_mitm6 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 stop_mitm6. 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.
stop_mitm6 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.
Start from Pentester-MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
