Why get_similar_movies needs a policy

The tool retrieves and returns data (similar movie information) based on a query parameter. It has no side effects, cannot modify data, and does not execute code or trigger financial transactions. This is a pure Read operation consistent with search and query capabilities mentioned in the server's purpose.

From the tool's definition Tool description states it 'Get movies similar to a given movie' using TMDB's similarity algorithm. This is a query/retrieval operation with no capability to modify, delete, or execute external operations.

POLICY

How to control get_similar_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 get_similar_movies:

policy.json

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

get_similar_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.
