THE RISK

Low Risk

Why compare_movies needs a policy

This tool queries The Movie Database API to fetch and display comparative information about multiple movies. It has no side effects, does not execute code or shell commands, does not create or modify data, and does not delete or perform financial transactions. The action is purely informational retrieval, fitting the 'Read' category with minimal risk to system integrity.

From the tool's definition The tool 'compare_movies' retrieves and presents information about movies (ratings, runtime, genres, cast, director, watch providers) without modifying, executing, or deleting any data. The description explicitly indicates a read-only comparison operation.

POLICY

How to control compare_movies

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

policy.json

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

compare_movies 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 Tmdb — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
