THE RISK

Medium Risk

Why word_applyTableAutoFormat needs a policy

This tool modifies table styling and formatting within a Word document. While the changes are reversible (can be undone or reformatted), it still constitutes a write operation that alters document content. The severity is medium because unintended formatting changes could affect document presentation and layout, but the impact is non-destructive and reversible.

From the tool's definition Tool applies formatting to tables via 'Applies a predefined style or autoformat to a table.' Formatting changes are reversible modifications to document structure and appearance.

POLICY

How to control word_applyTableAutoFormat

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_applyTableAutoFormat:

policy.json

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

word_applyTableAutoFormat 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.
