add_rating · Trakt MCP Server MCP: Risk & Policy

WHAT IT DOES

What add_rating does on Trakt MCP Server

AI agents use add_rating to create or update resources in Trakt MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Trakt MCP Server environment.

WHY IT NEEDS A POLICY

Why add_rating needs a policy

This tool creates or modifies rating data in Trakt's database, which is reversible—ratings can be updated or deleted. It does not execute code, delete data irreversibly, or involve financial transactions. It is a Write operation with low severity because misuse only affects the user's own rating records without broad destructive impact or external side effects.

From the tool's definition add_rating creates or modifies user rating data (1–10 scale) for movies, shows, seasons, or episodes. The verb 'add' and the action of recording ratings indicates creation/modification of user preferences.

Verdict

add_rating Rate-limited

add_rating 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.
