Mind Blown...Again. MCP, Roo Code and Youtube

Just had to share this with the enthusiasts. In 3 minutes, I got Roo Code (VS code extension...technically i had it running in Windsurf IDE) to build its own MCP for fetching and processing Youtube transcripts. In one prompt, my Roo now gets the transcript, saves it to a file and will process it however you want.... exact transcript, cleaned up markdown, thoughtful summarized takeaways, etc. I've played around in the past with expansive hobby-code to "extract knowledge" from YT videos and analyze and structure output in various ways. Now Roo does this with one prompt using its own MCP with complete flexibility. This is some awesome (and scary) sh;t!

So you're aware, the newest nOOb can pull this off... so please try this for yourselves. The prompt to Roo was simply "create a mcp you can use to fetch youtube transcripts using the youtube-transcript-api library when the user supplies a youtube url". Not exactly rocket science. You could make this much better, but Roo (claude 3.5) one-shotted it before i could even think about improving it.

The costs for this was pennies, and if your careful, you could make it virtually free by using experimental gemini models... or my favorite $ hack.... v3 and R1. The OG 3.5 killed it for $0.39..... haven't tried the others where I'm sure it can be done probably for $0.01, or using a reasoning model with the MCP to create some amazing analysis. Go try it!! 🤯
