Get the list of graders assigned to a specific question (instructor/TA only).
AI agents call tool_get_assignment_graders to retrieve information from Gradescope MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation to retrieve information about grader assignments. It has no side effects, does not modify data, and simply returns existing assignment data. The narrow scope (graders for a single question) and read-only nature result in low severity even in an educational grading context.
From the tool's definition Tool name includes 'get' and description states it retrieves 'the list of graders assigned to a specific question' with no mention of modification, deletion, or execution of operations.
Documented attack patterns abuse exactly the kind of access tool_get_assignment_graders gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Gradescope MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for tool_get_assignment_graders:
{
"version": "1",
"default": "deny",
"tools": {
"tool_get_assignment_graders": {}
}
}tool_get_assignment_graders is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the list of graders assigned to a specific question (instructor/TA only). It is categorised as a Read tool in the Gradescope MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Gradescope MCP Server MCP server in PolicyLayer and add a rule for tool_get_assignment_graders: 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 Gradescope MCP Server. Nothing to install.
tool_get_assignment_graders 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 tool_get_assignment_graders 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 tool_get_assignment_graders. 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.
tool_get_assignment_graders is provided by the Gradescope MCP Server MCP server (yuanpeng-li/gradescope-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Gradescope MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
