Why cancel_print_job needs a policy

Cancelling a print job is irreversible — once cancelled, the job is removed from the queue and cannot be restored. The 'cancel all jobs' variant has a broader blast radius. This maps to Destructive since the action cannot be undone.

From the tool's definition Cancel a specific print job by job ID or cancel all jobs for a printer

POLICY

How to control cancel_print_job

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

policy.json

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

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

Create a free account and register MCP Printer Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
