THE RISK

Why debug_element_mappings needs a policy

This tool reads and displays internal element mapping data for a slide for debugging purposes. 'Inspect' implies a read-only operation with no side effects. Severity is low as it only exposes internal debug information about presentation structure.

POLICY

How to control debug_element_mappings

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 debug_element_mappings:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "debug_element_mappings": {}
  }
}

debug_element_mappings is read-only, so it stays allowed — but 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.
