Fetch the hierarchical gradebook for a specific course.
AI agents call get_course_grades to retrieve information from Ekursy Mcp Py without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves grade information from a course without creating, modifying, or deleting any data. It is a read-only operation. Severity is medium rather than low because grades are sensitive personal educational data that could be misused if an AI agent fetches grades for students without authorization or uses the data inappropriately, though the tool itself has no destructive capability.
From the tool's definition Tool name 'get_course_grades' and description 'Fetch the hierarchical gradebook for a specific course' indicate a retrieval operation with no modification or deletion of data.

Register the Ekursy Mcp Py MCP server in PolicyLayer and add a rule for get_course_grades: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Ekursy Mcp Py. Nothing to install.
get_course_grades is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_course_grades rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_course_grades. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_course_grades is provided by the Ekursy Mcp Py MCP server (markrz-0/ekursy-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
