THE RISK

Why km_manage_group needs a policy

The tool supports deletion of macro groups, which is irreversible. Deleting a macro group in Keyboard Maestro would permanently remove all macros within that group, representing significant destructive potential. The presence of create/toggle/list operations does not reduce the severity since the most severe applicable category must be chosen.

From the tool's definition Manage macro groups (create, delete, toggle, list) — explicitly includes 'delete' operation

POLICY

How to control km_manage_group

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_manage_group:

policy.json

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

km_manage_group 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.
