What insert_paragraph does on Docx

AI agents use insert_paragraph 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.

Why insert_paragraph needs a policy

The tool creates new document content by inserting paragraphs, which qualifies as Write category. It is reversible (not Destructive), does not execute arbitrary code (not Execute), and does not involve financial transactions.

From the tool's definition Tool description states 'Insert a new paragraph' which creates new content in the document. This is a content modification operation that is reversible (paragraphs can be deleted).

Documented attack patterns abuse exactly the kind of access insert_paragraph gives an agent:

How to control insert_paragraph

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 insert_paragraph:

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

insert_paragraph 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.
