WHAT IT DOES

What delete_comment does on Docx

AI agents call delete_comment 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.

RISK

Why delete_comment is rated Critical

This tool irreversibly deletes comments and their associated markers from a Word document. Once deleted, the comment and its markers cannot be recovered through normal means. While the blast radius is moderate (comments are typically metadata rather than core document content), the irreversible nature places it in the Destructive category rather than Write.

From the tool's definition Tool name is 'delete_comment' and description states 'Delete a comment and remove its range markers from the document.' The use of 'Delete' and 'remove' indicates irreversible removal of data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs delete_comment safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Docx, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_comment, this is the rule to start with:

delete_comment Hidden

delete_comment is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.

The button opens the PolicyLayer dashboard: create your workspace, connect Docx, apply this rule, and every delete_comment call is checked against it from then on.
