Get grades for every student in a lesson. Optionally filter by class. Results sorted highest to lowest.
AI agents call get_lesson_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 educational grade data without modifying, deleting, or executing anything. While grade data may be sensitive within an educational context, the read-only nature means there are no side effects, no data loss risk, and minimal blast radius if misused by an AI agent—worst case being unauthorized viewing of grades. This falls squarely into the Read category with low severity.
From the tool's definition Tool description states 'Get grades for every student in a lesson' with optional filtering. The server description explicitly states 'read-only access' to Firebase data.

Get grades for every student in a lesson. Optionally filter by class. Results sorted highest to lowest. It is categorised as a Read tool in the Easycslearning MCP Server, which means it retrieves data without modifying state.
Register the Easycslearning MCP server in PolicyLayer and add a rule for get_lesson_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 Easycslearning. Nothing to install.
get_lesson_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_lesson_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_lesson_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_lesson_grades is provided by the Easycslearning MCP server (tsfir/easycslearning_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
