It is a purely informational read operation, consistent with other similar tools in the server like 'get_assignments' and 'get_course_announcements'.

POLICY

How to control find_relevant_materials

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 find_relevant_materials:

policy.json

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

find_relevant_materials 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.
