Why create_from_markdown needs a policy

The tool name 'create_from_markdown' explicitly indicates document creation. Given the server's stated purpose of 'editing and validating Microsoft Word documents' and the presence of similar write operations among sibling tools (add_comment, add_bookmark, add_content_control), this tool creates or generates new document structures. This is reversible via undo/deletion, making it Write rather than Destructive.

From the tool's definition Tool named 'create_from_markdown' with no description provided. Based on sibling tools (create, update operations) and server context (editing Word documents), this creates new document content from markdown input, which is a write/create operation.

POLICY

How to control create_from_markdown

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 create_from_markdown:

policy.json

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

create_from_markdown 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.

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.
