## Why scrub_pii is rated Critical

'Scrubbing' PII typically means permanently removing or overwriting sensitive personal data from documents, which is an irreversible destructive operation. Given the server context (Word document manipulation at OOXML level), this likely modifies document content by permanently deleting PII fields. Confidence is reduced due to the empty description, but the name strongly implies destructive data removal.

From the tool's own definition: "Tool name 'scrub_pii' implies irreversible removal of personally identifiable information from documents. The description is empty, providing no additional context."

## Use case

AI agents call scrub_pii to permanently remove resources in Docx, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Docx:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "scrub_pii"
  ]
}
```
