## Why get_grade_history is rated Low

This tool queries and retrieves historical grade information from PowerSchool. It performs a read-only operation (get) with optional filtering parameters but does not create, modify, delete, or execute any actions. The blast radius of misuse is minimal—an AI agent could over-retrieve grade data but cannot alter records or cause financial harm.

From the tool's own definition: "Tool name 'get_grade_history' and description 'Get historical grade data with optional date range filtering' indicate data retrieval with no modification, deletion, or execution."

## Use case

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