Get courses where the student is below a given grade threshold. Useful for quickly finding classes at risk of failing or needing improvement.
AI agents call get_failing_or_low_grades to retrieve information from School MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and filters grade information from the StudentVue dashboard based on a threshold parameter. It performs a read-only query with no capability to modify data, execute external operations, or produce irreversible effects. The severity is low because misuse would only expose academic information to an unauthorized user, not enable financial harm, data destruction, or system compromise.
From the tool's definition Tool name 'get_failing_or_low_grades' and description 'Get courses where the student is below a given grade threshold' indicate a retrieval operation that queries existing academic data without modification or side effects.
