Obtiene la calificación de un estudiante en un quiz específico
AI agents call get_quiz_grade to retrieve information from Moodle MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing student quiz grade information without modifying, deleting, or executing any actions. It is a read-only operation similar to the sibling tools get_assignments, get_submissions, and get_quizzes, which all retrieve data. The blast radius of misuse is low—unauthorized grade viewing is a confidentiality concern but causes no system changes.
From the tool's definition Tool name and description indicate retrieval of quiz grade data: 'Obtiene la calificación de un estudiante en un quiz específico' (Gets the grade of a student in a specific quiz). The verb 'obtiene' (retrieves/gets) is a read operation with no modification.

"get_quiz_grade": {}
}
}get_quiz_grade is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
