Get all lesson grades for a single student across an entire course.
AI agents call get_student_grades to retrieve information from Easycslearning without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing grade data for a student without creating, modifying, deleting, or executing any operations. It is a straightforward query operation against educational records. The read-only nature of the server and the retrieval-only semantics place it firmly in the Read category.
