POLICY

How to control string_set

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

policy.json

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

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