cancel_task · Auto Video Generator MCP: Risk & Policy

WHAT IT DOES

What cancel_task does on Auto Video Generator

AI agents invoke cancel_task to trigger actions in Auto Video Generator. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why cancel_task needs a policy

Cancelling a task triggers an external operation that terminates an in-progress process. This is not a simple read, and while it could be considered somewhat destructive to the task itself, it primarily executes a control action (cancellation) against a running operation.

Verdict

cancel_task Rate-limited

cancel_task stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
