proxychains_run · Proxychains MCP Server MCP: Risk & Policy

WHAT IT DOES

What proxychains_run does on Proxychains MCP Server

AI agents invoke proxychains_run to trigger actions in Proxychains 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 proxychains_run needs a policy

This tool executes arbitrary commands on a remote Linux host (Kali Linux) via a proxy chain. While the primary purpose is network routing for testing, the ability to 'run a command' means an AI agent could execute any shell command with the privileges of the SSH user, including data exfiltration, system modification, or malicious activities.

From the tool's definition Tool name and description: 'Run a command through the proxy chain' and 'The command will be routed through all configured proxies.' The verb 'run' combined with 'command' indicates arbitrary code execution.
