Why word_createDocument needs a policy

Creating a new document is a write operation that generates new data reversibly. Unlike destructive actions (delete, drop), the document can be closed without saving or deleted afterward. The blast radius is minimal—a blank document creates no meaningful side effects. Severity is low because the operation is non-destructive and isolated to document creation without modifying existing data.

From the tool's definition Tool name 'word_createDocument' and description 'Creates a new, blank Word document' indicate document creation, a write operation.

How to control word_createDocument

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Office Interop Word Server, and nothing reaches the server without passing your rules. This is the rule we recommend for word_createDocument:

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

word_createDocument 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.
