      "args": ["-m", "riocloud_reader.mcp"]
    }
  }
}

Configuration

Environment Variables

Variable	Required For	Description
TG_API_ID	Telegram	API ID from my.telegram.org
TG_API_HASH	Telegram	API Hash from my.telegram.org

Advanced Features

YouTube Groq Whisper Fallback

When YouTube videos don't have captions, riocloud-reader automatically falls back to Groq Whisper API for transcription.

# Set up Groq API key
export GROQ_API_KEY=your_groq_api_key

# Now any YouTube video will be transcribed
riocloud-reader https://youtube.com/watch?v=xxx

Get your free API key at: https://console.groq.com/

Bare Domain Support

You can use bare domain names without https:// prefix:

riocloud-reader example.com
riocloud-reader example.com/path
riocloud-reader twitter.com/elonmusk/status/123456

Obsidian Vault Integration

Save content directly to your Obsidian vault:

# Save to Obsidian vault
riocloud-reader https://youtube.com/watch?v=xxx --obsidian /path/to/vault

# Or use environment variable
export OBSIDIAN_VAULT=/path/to/vault
riocloud-reader https://twitter.com/user/status/123

Creates date-based folder structure:

vault/
├── 2026-02/
│   ├── youtube/
│   │   └── dQw4w9WgXcQ_Test Video.md
│   └── twitter/
│       └── abc123_Tweet by User.md

Twitter Login Session

For better Twitter/X coverage, log in to preserve session:

# First, log in (opens browser)
riocloud-reader login twitter

# Then use Twitter URLs - will use session if available
riocloud-reader https://x.com/user/status/123456

This uses three-tier fallback: FxTwitter API → Nitter → Playwright with session

Configuration File

Create a .env file:

cp .env.example .env
# Edit with your credentials
