bazarr_reset_providers · Nas MCP: Risk & Policy

WHAT IT DOES

What bazarr_reset_providers does on Nas

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

WHY IT NEEDS A POLICY

Why bazarr_reset_providers needs a policy

This tool resets throttled providers, which is a state modification (clearing throttle/rate-limit state) that allows new searches to proceed. It modifies system state reversibly — providers can be throttled again naturally — making it a Write operation rather than Destructive. Misuse could cause excessive requests to subtitle providers, hence medium severity.
