edit_element

THE RISK

Medium Risk

Why edit_element needs a policy

This tool modifies data (presentation element properties) reversibly without deleting or destroying information. It falls under Write category as it updates existing elements. Severity is medium because misuse could corrupt presentation formatting or content, but changes are typically undoable in PowerPoint (undo/redo stack) and don't cause permanent data loss or execute arbitrary code.

From the tool's definition Tool description states 'Edit an element's properties' which modifies existing presentation content. The server context confirms this is for 'create and manipulate PowerPoint presentations.'

POLICY

How to control edit_element

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

policy.json

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

edit_element 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 PowerPoint 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.
