WHAT IT DOES

What list_database_presets does on Moodle

AI agents call list_database_presets to retrieve information from Moodle without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`databaseId`	integer	Yes	The database's id (course module id), as get_course_structure gives it

Parameters from the server's own tool schema.

RISK

Why list_database_presets is rated Low

Even though list_database_presets only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access
