WHAT IT DOES

What create_wiki_page does on Moodle

AI agents use create_wiki_page 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
`embed`	array	—	Absolute local files to embed in the content (HTML pages), which names each by its file name: <img src="shot.png">
`title`	string	Yes
`wikiId`	integer	Yes	The wiki's id (course module id), as get_course_structure gives it
`content`	string	Yes	No aliases in it
`groupId`	integer	—	A group's subwiki, in a wiki with groups; the person's own when missing
`participant`	string	—	A participant's subwiki in an individual wiki, by alias when the server pseudonymizes
`participantId`	integer	—	Or by user id, when the server shows names

Parameters from the server's own tool schema.

RISK

Why create_wiki_page is rated Medium

An AI agent can call create_wiki_page 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.

RECOMMENDED RULE

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

create_wiki_page Rate-limited

create_wiki_page 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.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_wiki_page": {
      "limits": [
        {
          "counter": "create_wiki_page_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 create_wiki_page call is checked against it from then on.

A subwiki's first page must have the wiki's first page title. Returns the page. Others in the course read it: confirm with the person first. It is categorised as a Write tool in the Moodle MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What risk level is create_wiki_page? +
