Why km_get_errors needs a policy

This tool retrieves and queries logging/diagnostic information from the Keyboard Maestro Engine. It performs a simple read operation on existing log data—no creation, modification, deletion, or execution of commands. The information returned is purely informational for debugging purposes. This is a low-severity read operation with minimal security risk.

From the tool's definition Tool description states it 'Get[s] recent errors and failures from Keyboard Maestro Engine log' and 'Returns errors grouped by macro with timestamps and error messages.' The verb 'Get' and 'Returns' indicate data retrieval with no modification or side effects.

How to control km_get_errors

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_get_errors:

policy.json

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

km_get_errors 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.
