THE RISK

Why word_deleteText needs a policy

This tool permanently removes data from a Word document. While Word has undo functionality, in an automated MCP agent context, deleted text cannot be reliably recovered once the document is saved or the session ends. Deletion is irreversible and represents data loss, placing it in the Destructive category.

From the tool's definition Tool name 'word_deleteText' and description states it 'Deletes text relative to the current selection' — deletion is irreversible without undo capability guarantee in automated context.

POLICY

How to control word_deleteText

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "word_deleteText"
  ]
}

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