Why update_message_template_folder needs a policy

This tool modifies configuration/organizational metadata (message template folders) reversibly. It is not a destructive deletion, does not execute arbitrary code or commands, does not handle financial transactions, and does not retrieve data. The blast radius is limited to message template organization—affecting business workflow but recoverable through reversal.

From the tool's definition Tool name 'update_message_template_folder' and description 'Update a message template folder' indicate modification of existing data (templates/folders) within the Frontapp system.

POLICY

How to control update_message_template_folder

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "update_message_template_folder": {
      "limits": [
        {
          "counter": "update_message_template_folder_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

update_message_template_folder stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
