Defaulting to Other with low confidence due to insufficient information, though the 'diagnosis' suffix suggests a read/query operation.

POLICY

How to control esm_kafka_diagnosis

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

policy.json

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

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

Create a free account and register Amazon Redshift MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
