YouTube transcripts as token-efficient AI context. One fetch, cached forever.

Agent-first: returns structured JSON by default. Zero dependencies on yt-dlp, ffmpeg, or API keys.

Works with Claude Desktop, ChatGPT Desktop, Cursor, Windsurf, and any MCP client.

## Why?

When AI browses YouTube for a transcript, it processes the entire page: navigation, ads, recommendations, scripts. That's 75,000-150,000 tokens of noise to extract maybe 6,000 tokens of actual content.

This tool fetches only the transcript.

| | Tokens | Speed | Repeat queries |
|-|--------|-------|----------------|
| AI browses YouTube | 75-150k | 20-90s | Same cost every time |
| **ytfetch-mcp** | 6-12k | 1-3s | Instant (cached) |

~50 KB per video in cache. A year of daily use stays under 120 MB.
