What set_document_protection does on Docx

AI agents use set_document_protection 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.

Medium Risk

Why set_document_protection needs a policy

The tool creates or modifies document protection settings reversibly—protection can be added, removed, or changed. This is a Write operation (modification without deletion). Severity is medium because while it affects document security posture and could restrict legitimate access or hide modifications, the changes are reversible and don't destroy data or move money.

From the tool's definition Tool name 'set_document_protection' with description indicating it sets protection modes including 'trackedChanges/comments/readOnly/forms/none'. This modifies document metadata and access controls.

How to control set_document_protection

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 set_document_protection:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_document_protection": {
      "limits": [
        {
          "counter": "set_document_protection_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

set_document_protection 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.

  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.
