Why CancelAHORunBatch needs a policy

Cancellation of a batch run constitutes an irreversible action that cannot be undone—once cancelled, the batch operation is terminated and any partial progress is lost. This fits the Destructive category (actions that cannot be undone) rather than Write (reversible modifications).

From the tool's definition Tool name 'CancelAHORunBatch' suggests cancellation of a batch operation, which is an irreversible action that terminates an in-progress process.

POLICY

How to control CancelAHORunBatch

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS Labs Amazon Q Business anonymous mode 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",
  "hide": [
    "CancelAHORunBatch"
  ]
}

CancelAHORunBatch disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
