THE RISK

High Risk

This tool triggers an external operation on a running LibreOffice application by sending a signal to reload a document. It interacts with an external process (LibreOffice) and causes it to perform an action, placing it in the Execute category. Misuse could cause loss of unsaved changes if a document is reloaded unexpectedly, giving it medium severity.

HOW TO CONTROL REFRESH_DOCUMENT_IN_LIBREOFFICE

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "refresh_document_in_libreoffice": {
      "limits": [
        {
          "counter": "refresh_document_in_libreoffice_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

refresh_document_in_libreoffice stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register LibreOffice MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
