Why update_page needs a policy

This tool creates or modifies data reversibly by updating page content in Docmost. While not destructive (no permanent deletion), and not executing arbitrary code, it does alter stored documentation state. Medium severity reflects that misconfigured updates could corrupt documentation, but changes are typically reversible via version history or manual correction.

From the tool's definition Tool name 'update_page' and description 'Update a page' indicate modification of existing documentation. Server description confirms it 'modify[ies]... documentation pages'.

POLICY

How to control update_page

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

policy.json

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

update_page 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 Docmost 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.
