Why delete_content_control needs a policy

This tool performs irreversible deletion of document structural elements (content controls/SDTs). Although content is retained, the removal of the wrapper cannot be undone through normal document operations and alters the document's structure permanently. This qualifies as Destructive rather than Write due to the irreversible nature of structural manipulation.

From the tool's definition Tool name 'delete_content_control' and description 'Remove an SDT content control wrapper' indicate irreversible deletion of document structure elements.

POLICY

How to control delete_content_control

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 delete_content_control:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_content_control"
  ]
}

delete_content_control disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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.

How do I enforce a policy on delete_content_control? +

Register the Docx MCP server in PolicyLayer and add a rule for delete_content_control: 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 delete_content_control? +
