THE RISK

Low Risk

Why list_presentations needs a policy

This tool queries and returns information about existing PowerPoint files without modifying, executing, or deleting any data. It is purely informational retrieval, fitting the Read category. Severity is low because listing files poses minimal risk—an AI misuse would at worst expose file names and metadata already known to entities with workspace access.

From the tool's definition Tool name 'list_presentations' and description 'List all PowerPoint files in the workspace' indicate a retrieval operation with no side effects.

POLICY

How to control list_presentations

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 list_presentations:

policy.json

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

list_presentations 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.
