What delete_text does on Docx

AI agents call delete_text to permanently remove resources in Docx — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

Critical Risk

Why delete_text needs a policy

The tool deletes text from Word documents, which is an irreversible operation that cannot be undone through normal tool invocation. Although the tool description is empty, the name combined with the server's stated editing capabilities and the presence of other modification tools (accept_change, add_comment, add_equation) establishes that this performs destructive editing.

From the tool's definition Tool name 'delete_text' and server context describing 'editing and validating Microsoft Word documents' indicates irreversible deletion of document content.

How to control delete_text

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

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_text"
  ]
}

delete_text disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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