What delete_activity does on Moodle
AI agents call delete_activity to permanently remove resources in Moodle, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
| Parameter | Type | Required | Description |
|---|---|---|---|
courseId | integer | Yes | The course's id, as list_courses gives it |
activityId | integer | Yes | The activity's id (course module id), as get_course_structure gives it |
Parameters from the server's own tool schema.
Why delete_activity is rated Critical
An AI agent that decides to call delete_activity doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Moodle is gone. There is no undo for destructive operations.
Attacks that exploit this kind of access
The rule that runs delete_activity 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 delete_activity, this is the rule to start with:
delete_activity is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Moodle, apply this rule, and every delete_activity call is checked against it from then on.

delete_activity is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_activity rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_activity. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
delete_activity is provided by the Moodle MCP server (@falkenslab/moodle-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
