What meshy_cancel_task does on Meshy MCP Server

AI agents call meshy_cancel_task to permanently remove resources in Meshy MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

THE RISK

Why meshy_cancel_task needs a policy

Cancelling a running task is irreversible — the in-progress generation work is terminated and cannot be resumed. This is a destructive operation that permanently stops and discards the task's progress, even though no stored data is deleted.

From the tool's definition Cancel a pending or in-progress 3D generation task... cancels a task that is currently PENDING or IN_PROGRESS

POLICY

How to control meshy_cancel_task

PolicyLayer is an MCP gateway — it sits between your AI agents and Meshy MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for meshy_cancel_task:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "meshy_cancel_task"
  ]
}

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

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
