Why get_overdue_assignments needs a policy

This tool queries Moodle LMS to retrieve information about overdue assignments. It performs data retrieval only (Returns, sorted by) without creating, modifying, deleting, or executing any operations. The sorting is applied to query results, not a state-changing action. This is a straightforward Read operation with minimal risk.

From the tool's definition Tool description states it 'Returns assignments past due date that are unsubmitted' — a query operation that retrieves and sorts existing data with no modification or side effects.

POLICY

How to control get_overdue_assignments

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

policy.json

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

get_overdue_assignments 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 Moodle-MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
