metasploit_run · Kali MCP: Risk & Policy

WHAT IT DOES

What metasploit_run does on Kali

AI agents invoke metasploit_run to trigger actions in Kali. 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

This tool allows execution of arbitrary Metasploit modules, which can perform a wide range of operations from network exploitation to payload delivery. The effects are unpredictable and depend entirely on user input (module selection and configuration).

From the tool's definition Tool description explicitly states "Execute a Metasploit module." Metasploit is a framework for running arbitrary exploit code, payloads, and attack modules whose effects are entirely dependent on which module and parameters are provided.

Verdict

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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Kali, so you can run agents against it safely.

FAQ

Questions about metasploit_run

What does the metasploit_run tool do? +

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

How do I enforce a policy on metasploit_run? +

Register the Kali 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. 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 MCP server (pentestt00ls/kali-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
