# set_rubric

Define how an assignment is graded with a rubric (criteria, each with two levels or more: a definition and its score) or a marking guide (criteria, each with a short name, a description for students, one for markers and a maximum score, and the guide's frequently used comments), through Moodle's advanced grading editor, ready to use. Creates one where there is none and replaces the one there is, so its criterion and level ids change. Refused once anything has been graded with it: Moodle would regrade. Returns the definition as get_rubric gives it. Changes how students are graded: confirm with the person first.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "set_rubric",
    "arguments": {
      "name": "<name>",

## Why set_rubric is rated Medium

An AI agent can call set_rubric 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.

Risk signals: High parameter count (13 properties)

## Use case

AI agents use set_rubric 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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Moodle:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_rubric": {
      "limits": [
        {
          "counter": "set_rubric_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
