proc_sudo · Mcp Ssh Tool MCP: Risk & Policy

WHAT IT DOES

What proc_sudo does on Mcp Ssh Tool

AI agents invoke proc_sudo to trigger actions in Mcp Ssh Tool. 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 proc_sudo needs a policy

This tool runs arbitrary commands with root/sudo privileges on a remote SSH host. An AI agent could use this to execute any system command as superuser, giving it unrestricted access to the entire system — including installing software, modifying system files, creating backdoors, or destroying data. The blast radius is maximal: full system compromise is possible.

From the tool's definition "Executes a command with sudo privileges"

Verdict

proc_sudo Rate-limited

proc_sudo 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.

What risk level is proc_sudo? +

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

Can I rate-limit proc_sudo? +

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

Set action: deny in the PolicyLayer policy for proc_sudo. 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.
