WHAT IT DOES

What reply_to_comment does on Docx

AI agents use reply_to_comment to create or update resources in Docx, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Docx environment.

RISK

Why reply_to_comment is rated Medium

This tool creates new data (a reply/threaded comment) within a Word document. It modifies the document by adding content, but the modification is reversible (replies can be deleted or edited). This is a Write operation rather than Read (it creates, not just retrieves), Execute (it doesn't run arbitrary code), or Destructive (replies don't irreversibly delete data).

From the tool's definition Tool name 'reply_to_comment' and description 'Reply to an existing comment (creates a threaded reply)' indicates creation of new comment data within a document.

RECOMMENDED RULE

The rule that runs reply_to_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 reply_to_comment, this is the rule to start with:

reply_to_comment Rate-limited

reply_to_comment 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.

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