Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

youtube-music-cli-mcp-fork GEMINI.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

@involvex/youtube-music-cli is a high-performance, feature-rich Terminal User Interface (TUI) music player for YouTube Music. It is built with React and TypeScript, using Ink for terminal rendering and Bun as the primary runtime.

Key Features

  • TUI/CLI Hybrid: Supports both a full interactive TUI and direct CLI commands (e.g., play, search).
  • Audio Engine: Powered by mpv with JSON IPC control for precise playback management.
  • API Integration: Uses youtubei.js (Innertube) for interacting with YouTube Music.
  • Plugin System: Extensible architecture allowing for features like adblocking, lyrics, and Discord Rich Presence.
  • State Management: Robust custom store pattern using React Context and useReducer.
  • Persistence: Local configuration and player state persistence (history, queue, volume).

Core Tech Stack

  • Runtime: Bun (supports Node.js compatibility).
  • UI: React + Ink (Terminal UI).
  • Language: TypeScript (ESM).
  • Audio: mpv (via spawn and IPC socket).
  • Extraction: yt-dlp (via mpv integration).

Architecture

1. Entry Points

  • source/cli.tsx: The main entry point. Parses CLI arguments using meow, handles direct commands, and renders the App component for the TUI.
  • source/app.tsx: Root React component that sets up providers and the main UI shell.

2. State Management (source/stores/)

The project uses a predictable state management pattern:

  • PlayerProvider: Manages playback state, queue, volume, and shuffle/repeat modes.
  • FavoritesProvider: Manages favorite tracks and their persistence.
  • NavigationProvider: Handles view transitions and navigation history.
  • PluginsProvider: Manages the lifecycle and state of loaded plugins.

3. Service Layer (source/services/)

Services provide a singleton-based abstraction for side effects:

  • PlayerService: Low-level mpv process management and IPC communication.
  • MusicService: High-level wrapper for YouTube Music search and metadata retrieval.
  • FavoritesService: Manages favorite tracks persistence (favorites.json).
  • ConfigService: Manages user configuration stored in ~/.youtube-music-cli/config.json.
  • PluginService: Handles plugin discovery, installation, and activation.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
