THE RISK

Low Risk

Why CancelAHORunBatch needs a policy

The description is empty, making confident classification impossible. The name suggests cancelling a batch run (possibly an AWS Health Operations batch), which could be an Execute or Write action (stopping/cancelling an in-progress operation), but without further detail, confidence is very low. Defaulting to Other with reduced confidence.

From the tool's definition Tool name 'CancelAHORunBatch' and empty description provide minimal information for classification.

POLICY

How to control CancelAHORunBatch

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

policy.json

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

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