AI agents call CancelAHORunBatch to permanently remove resources in Amazon Data Processing MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Canceling a batch run is a destructive action—it terminates an operation whose results or state cannot be fully recovered once canceled. While not data deletion, it represents an irreversible operational state change with potential loss of compute resources or partial results. The lack of description lowers confidence slightly, but the Cancel verb and batch context strongly suggest destructive intent.
From the tool's definition Tool name 'CancelAHORunBatch' indicates cancellation of a batch run operation. The 'Cancel' action on an in-progress batch job typically stops execution and may discard intermediate results, which is an irreversible state change.
Documented attack patterns abuse exactly the kind of access CancelAHORunBatch gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Data Processing MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for CancelAHORunBatch:
{
"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.

CancelAHORunBatch. It is categorised as a Destructive tool in the Amazon Data Processing MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Amazon Data Processing MCP Server MCP server in PolicyLayer and add a rule for CancelAHORunBatch: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Amazon Data Processing MCP Server. Nothing to install.
CancelAHORunBatch is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the CancelAHORunBatch rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for CancelAHORunBatch. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
CancelAHORunBatch is provided by the Amazon Data Processing MCP Server MCP server (awslabs.aws-dataprocessing-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
