metasploit_run · Kali Linux MCP Server MCP: Risk & Policy

WHAT IT DOES

What metasploit_run does on Kali Linux MCP Server

AI agents invoke metasploit_run to trigger actions in Kali Linux MCP Server. 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.

WHY IT NEEDS A POLICY

Why metasploit_run needs a policy

Metasploit modules execute arbitrary code and can trigger real attacks, shell access, or compromise target systems. This is Execute (not Destructive) because the irreversibility depends on the specific module chosen, but the tool itself provides the capability to execute external code/operations. Critical severity due to the broad attack surface and potential for complete system compromise via exploitation.

From the tool's definition Tool name 'metasploit_run' and description 'Execute a Metasploit module' directly indicate execution of code/modules.

metasploit_run Rate-limited

metasploit_run 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.

How do I enforce a policy on metasploit_run? +

Register the Kali Linux MCP Server MCP server in PolicyLayer and add a rule for metasploit_run: 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 Kali Linux MCP Server. Nothing to install.

What risk level is metasploit_run? +

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

Can I rate-limit metasploit_run? +

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

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

metasploit_run is provided by the Kali Linux MCP Server MCP server (ofryma/custom-mcp-library). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
