edit_quiz_slot
Change one slot of a quiz: its maximum mark, and where it is (after another slot, 0 for first, and on a page), as the edit page does. After attempts, Moodle lets the mark change (it regrades them) but not the order. Returns the quiz's structure. Changes the quiz: confirm with the person first.

Attacks that exploit this kind of access
The rule that runs edit_quiz_slot safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Moodle, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For edit_quiz_slot, this is the rule to start with:
edit_quiz_slot stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Moodle, apply this rule, and every edit_quiz_slot call is checked against it from then on.
