THE RISK

Medium Risk

Why set_section_properties needs a policy

This tool modifies document formatting (page size, orientation, margins) but does not delete, destroy, or execute arbitrary code. These changes are reversible—section properties can be changed again to restore prior state. The impact is confined to document layout metadata, affecting document appearance and printing but not deleting content or triggering external operations.

From the tool's definition Tool description: 'Modify section properties (page size, orientation, margins)'. The verb 'Modify' indicates reversible creation or alteration of document formatting properties.

POLICY

How to control set_section_properties

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_section_properties:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_section_properties": {
      "limits": [
        {
          "counter": "set_section_properties_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

set_section_properties 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.

Create a free account and register Docx — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about set_section_properties

What does the set_section_properties tool do? +

Modify section properties (page size, orientation, margins). 0/empty = unchanged. It is categorised as a Write tool in the Docx MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_section_properties? +

Register the Docx MCP server in PolicyLayer and add a rule for set_section_properties: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Docx. Nothing to install.

What risk level is set_section_properties? +

set_section_properties is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_section_properties? +

Yes. Add a rate_limit block to the set_section_properties rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block set_section_properties completely? +

Set action: deny in the PolicyLayer policy for set_section_properties. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides set_section_properties? +

set_section_properties is provided by the Docx MCP server (securityronin/docx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Docx tool call.

Start from Docx, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
