POLICY

How to control tool_prepare_grading_artifact

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_prepare_grading_artifact:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "tool_prepare_grading_artifact": {
      "limits": [
        {
          "counter": "tool_prepare_grading_artifact_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

tool_prepare_grading_artifact gets a rate cap, and everything else on the server is denied unless you say otherwise.
