WHAT IT DOES

What add_lesson_page does on Moodle

AI agents use add_lesson_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
`type`	string	Yes
`after`	integer	—	The page it goes after (0: first); last without it
`embed`	array	—	Absolute local files to embed in the contents, answers or responses
`title`	string	—
`fields`	object	—	Any other field of the page's form, by name (layout, display…)
`answers`	array	—	A question page's answers, in order (given, they replace them all); an essay or structural page's single row
`buttons`	array	—	A content page's buttons, in order; given, they replace them all
`contents`	string	—	The page's contents (HTML); local files it names (<img src="shot.png">) go in embed
`lessonId`	integer	Yes	The lesson's id (course module id), as get_course_structure gives it
`caseSensitive`	boolean	—	Short answer: answers compared case-sensitively
`multipleAnswers`	boolean	—	Multichoice: more than one answer can be right

Parameters from the server's own tool schema.

RISK

Why add_lesson_page is rated Medium

An AI agent can call add_lesson_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 add_lesson_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 add_lesson_page, this is the rule to start with:

add_lesson_page Rate-limited

add_lesson_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.

View as policy code

policy.json

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

FAQ

Questions about add_lesson_page

What does the add_lesson_page tool do? +

Add a page to a lesson through Moodle's lesson editor: a content page with its buttons, a question page (multichoice, truefalse, shortanswer, numerical, matching, essay) with its answers, responses, scores and jumps, or a cluster, end of cluster or end of branch; after a page, or last. A jump to a page the lesson doesn't have is refused before anything is saved, so add the pages first and set their jumps after with edit_lesson_page when they point forward. Returns the new page's id and the lesson's page ids in order. Changes the course: 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 parameters does add_lesson_page accept? +

add_lesson_page accepts 11 parameters: type, after, embed, title, fields, answers, buttons, contents, lessonId, caseSensitive, multipleAnswers. Required: type, lessonId. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on add_lesson_page? +

Register the Moodle MCP server in PolicyLayer and add a rule for add_lesson_page: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Moodle. Nothing to install.

What risk level is add_lesson_page? +

add_lesson_page is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit add_lesson_page? +

Yes. Add a rate_limit block to the add_lesson_page 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.

How do I block add_lesson_page completely? +

Set action: deny in the PolicyLayer policy for add_lesson_page. 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.

What MCP server provides add_lesson_page? +

add_lesson_page 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.
