Why run_scp needs a policy

SCP is an Execute-category tool because it runs external operations (file transfers, potentially remote command execution) whose effects depend on arguments (destination, source, host, credentials). While superficially similar to file operations, SCP involves triggering remote system actions.

From the tool's definition Tool named 'run_scp' with empty description on a penetration testing server ('Pentester-MCP') that 'enables AI assistants to autonomously execute over 200 open-source penetration testing tools.' SCP (Secure Copy Protocol) is a file transfer utility that…

POLICY

How to control run_scp

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 run_scp:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "run_scp": {
      "limits": [
        {
          "counter": "run_scp_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

run_scp 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.

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

FAQ

Questions about run_scp

What does the run_scp tool do? +

run_scp. 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 run_scp? +

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

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

Can I rate-limit run_scp? +

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

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

run_scp 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.
