Why km_list_macros needs a policy

This tool only retrieves and lists existing macros with their metadata (names and UIDs). It has no side effects, does not modify any data, and does not execute any macros. Pure read operation with minimal blast radius.

POLICY

How to control km_list_macros

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_list_macros:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "km_list_macros": {}
  }
}

km_list_macros is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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.
