WHAT IT DOES

What duplicate_activity does on Moodle

AI agents use duplicate_activity to create or update resources in Moodle, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Moodle environment.

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.

RISK

Why duplicate_activity is rated Medium

An AI agent can call duplicate_activity faster than any human can review: one bad instruction and it creates or modifies resources in Moodle by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs duplicate_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 duplicate_activity, this is the rule to start with:

duplicate_activity Rate-limited

duplicate_activity 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.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "duplicate_activity": {
      "limits": [
        {
          "counter": "duplicate_activity_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Moodle, apply this rule, and every duplicate_activity call is checked against it from then on.

How do I block duplicate_activity completely? +
