WHAT IT DOES

What timer_status does on Mcp Control Plane

AI agents call timer_status to retrieve information from Mcp Control Plane without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why timer_status is rated Low

This tool retrieves and displays the state of systemd timers and their execution history. It performs information gathering only—listing timers and reporting on their status (missed/failed activity)—without modifying, deleting, or executing anything. The blast radius of misuse is minimal: an attacker gains visibility into scheduled tasks but cannot trigger, disable, or alter them.

From the tool's definition Tool name 'timer_status' and description 'List systemd timers and recently missed/failed timer activity' indicate a pure query/listing operation with no side effects.

RECOMMENDED RULE

The rule that runs timer_status safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Control Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For timer_status, this is the rule to start with:

timer_status Allowed

timer_status is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "timer_status": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Control Plane, apply this rule, and every timer_status call is checked against it from then on.
