YouTube Channel Stats Extractor MCP Server

MCP server for the Mamba Labs YouTube Channel Stats Extractor actor on Apify.

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 not_extractable rather than as a video having no captions. No API key needed. Read only; requires an APIFY_TOKEN and consumes Apify credits per call.

Reading the output

Every row carries a per platform _status field, and it is the field to read first. The vocabulary is the same across the whole Mamba Labs social family:

false and null are never interchangeable. false means we looked and the answer is no. null means we could not look. If you filter for companies with no presence, filter on false, because null rows are unknown rather than absent.
