Plex Age Limit Setter

A FastAPI service that automatically sets content ratings on Plex media library items. Runs on a schedule and exposes an MCP (Model Context Protocol) endpoint for AI-agent-driven library management.

Features

• Scheduled sync — Periodically applies a target content rating to all items in a specified library
• Manual trigger — POST /trigger to run an immediate sync (rate-limited to 1 req/min)
• MCP tool server — POST /mcp exposes Plex operations as MCP tools for AI agents (list libraries, search movies, set ratings, batch update, manage collections, refresh/analyze libraries)
• Health endpoint — GET /health
