THE RISK

Low Risk

Why list_schedules needs a policy

This tool retrieves and enumerates scheduled tasks without modifying, deleting, or executing anything. It is a read-only operation that simply returns information about existing schedules. The low severity reflects minimal risk: exposure of scheduling metadata alone cannot cause harm unless combined with other tools to modify or delete schedules.

From the tool's definition Tool name is 'list_schedules' and description states 'List all locally-managed scheduled tasks' — a pure query operation with no side effects.

POLICY

How to control list_schedules

PolicyLayer is an MCP gateway — it sits between your AI agents and Jules MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_schedules:

policy.json

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

list_schedules is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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