msf_session_create

Create a new persistent Metasploit (msfconsole) session.

How to control msf_session_create ↓

AI agents invoke msf_session_create to trigger actions in Zebbern Kali 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

This tool launches a persistent Metasploit Framework session inside a Kali Linux penetration testing container. Metasploit is a full exploitation framework capable of running exploits, payloads, post-exploitation modules, and lateral movement operations. Creating a persistent msfconsole session gives an AI agent ongoing execution capabilities against arbitrary targets.

Documented attack patterns abuse exactly the kind of access msf_session_create gives an agent:

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

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

msf_session_create 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 Zebbern Kali 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.

What does the msf_session_create tool do? +

Create a new persistent Metasploit (msfconsole) session. It is categorised as a Execute tool in the Zebbern Kali 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 msf_session_create? +

Register the Zebbern Kali MCP server in PolicyLayer and add a rule for msf_session_create: 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 Zebbern Kali MCP. Nothing to install.

What risk level is msf_session_create? +

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

Can I rate-limit msf_session_create? +

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

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

msf_session_create is provided by the Zebbern Kali MCP server (zebbern/zebbern-kali-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Zebbern Kali MCP tool call.
