取消指定的处理任务
AI agents call cancelTask to permanently remove resources in Video Clip MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
An AI agent that decides to call cancelTask doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Video Clip MCP is gone — there is no undo for destructive operations.
Attacks that exploit this kind of access
取消指定的处理任务. It is categorised as a Destructive tool in the Video Clip MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Video Clip MCP server in PolicyLayer and add a rule for cancelTask: 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 Video Clip MCP. Nothing to install.

Yes. Add a rate_limit block to the cancelTask 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 cancelTask. 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.
cancelTask is provided by the Video Clip MCP server (pickstar-2002/video-clip-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
