crear_curso · Moodle MCP: Risk & Policy

WHAT IT DOES

What crear_curso does on Moodle

AI agents use crear_curso 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.

WHY IT NEEDS A POLICY

Why crear_curso needs a policy

The tool creates a new educational resource in Moodle (a course) with specified properties. This is a Write operation because it creates data that can be modified or deleted later (confirmed by sibling tools like archivar_curso and actualizar_curso which update or archive courses).

From the tool's definition "Create a new Moodle course" — creates new course with idnumber, default hidden state, and section structure. This is a reversible creation operation.

Verdict

crear_curso Rate-limited

crear_curso 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.
