Cancel a queued generation task.
AI agents call cancel_task to permanently remove resources in Wan2GP MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling a queued task is an irreversible action — once cancelled, the task's position in the queue and any partial computation are lost and cannot be recovered. This maps to the Destructive category. The blast radius is medium because it affects a single generation job rather than data storage or financial assets.

Attacks that exploit this kind of access
Cancel a queued generation task. It is categorised as a Destructive tool in the Wan2GP MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Wan2GP MCP Server MCP server in PolicyLayer and add a rule for cancel_task: 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 Wan2GP MCP Server. Nothing to install.
cancel_task 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 cancel_task 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 cancel_task. 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.
cancel_task is provided by the Wan2GP MCP Server MCP server (reverb256/wan2gp-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
