mambalabsdev/mcp-youtube-channel-transcript-extractor

MCP server for the Mamba Labs YouTube Channel Stats Extractor actor on Apify.
The npm package and the registry entry keep the name mcp-youtube-channel-transcript-extractor, so existing installs keep working; the product is YouTube Channel Stats Extractor.
Resolve a company domain or YouTube handle to the channel with subscriber count and channel metadata.
## What it does
Resolve a company domain, or a YouTube handle, to that company's YouTube channel. Returns the subscriber count, the stable UC channel id, channel name, creation date and description, as one flat Clay ready row. Subscriber counts are rounded by YouTube above roughly a thousand subscribers, on the page and in its official API alike, and the row flags that. Optional transcript pulling is available and is CURRENTLY GATED by YouTube: the caption track list is readable and the caption content endpoint returns an empty body without a proof of origin token, which the row reports as notextractable rather than as a video having no captions. No API key needed. Read only; requires an APIFYTOKEN and consumes Apify credits per call.
