POLICY

How to control ri-performance

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon EKS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for ri-performance:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ri-performance": {
      "limits": [
        {
          "counter": "ri-performance_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

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