restart_daemon · Ploi MCP Server MCP: Risk & Policy

WHAT IT DOES

What restart_daemon does on Ploi MCP Server

AI agents invoke restart_daemon to trigger actions in Ploi 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 restart_daemon needs a policy

Restarting a daemon is an execute operation: it runs a command on a managed server that changes system behavior and state. While not immediately destructive or data-altering, it can disrupt services, cause downtime, or affect application availability depending on which daemon is restarted and the server's configuration. The blast radius is significant in a production environment.

From the tool's definition Tool performs 'Restart a daemon' action, which triggers an external operation (daemon restart) whose effects depend on which daemon is targeted. This is an operational command that modifies system state.

Verdict

restart_daemon Rate-limited

restart_daemon 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.

FAQ

Questions about restart_daemon

What does the restart_daemon tool do? +

Restart a daemon (e.g. to pick up new code after a deploy). It is categorised as a Execute tool in the Ploi MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on restart_daemon? +

Register the Ploi MCP Server MCP server in PolicyLayer and add a rule for restart_daemon: 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 Ploi MCP Server. Nothing to install.

What risk level is restart_daemon? +

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

Can I rate-limit restart_daemon? +

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

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

restart_daemon is provided by the Ploi MCP Server MCP server (sudanese/ploi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
