This tool permanently removes macros without recovery options. The explicit warning about irreversibility and the use of 'delete' confirm Destructive category. Severity is high because losing automation macros could disrupt workflows, though it does not directly impact financial systems or access to critical infrastructure. Confidence is high due to clear destructive intent and explicit irreversibility warning.

From the tool's definition The tool description explicitly states 'Delete a macro by name or UID. WARNING: This cannot be undone!' The operation is irreversible deletion of data/configuration.

POLICY

How to control km_delete_macro

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

policy.json

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

km_delete_macro 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 Keyboard Maestro — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
