Synesthesia
Deep audio perception through analysis. Downloads from YouTube, analyzes with Essentia, fetches lyrics via LRCLIB. Returns BPM, mood, energy, spectrograms, and synced lyrics.
Why Local?
YouTube blocks downloads from datacenter IPs (like Cloudflare Workers and HuggingFace Spaces). This MCP runs locally on your machine with a residential IP, so downloads work.
