WHAT IT DOES

What hwp_close_all_documents does on HWP MCP Server

THE RISK

Critical Risk

Why hwp_close_all_documents needs a policy

This tool closes ALL open documents with save defaulting to False and dialog suppression defaulting to True — meaning unsaved changes across all open documents would be silently discarded. This is irreversible data loss at scale (all documents), making it Destructive with high severity.

From the tool's definition 모든 문서를 닫습니다 (closes all documents); save parameter defaults to False, suppress_dialog defaults to True

POLICY

How to control hwp_close_all_documents

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

policy.json

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

hwp_close_all_documents 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 HWP MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
