TubeSaku Creator Insights

TubeSaku provides read-only access to collected and analyzed Japanese-language YouTube creator data. Find upcoming streams, including VTuber debut candidates; search broadcasts that were live at their latest observation; and discover recorded VTubers by debut year, date range, game activity, name, and available introduction keywords. You can also compare weekly game demand and creator supply, explore singing-cover opportunities, and read published Google Trends and YouTube suggestion summaries.

No TubeSaku login or API key is required. Public access allows 20 tool executions and resource reads per MCP session, with a service-wide daily safety cap of 20,000 executions resetting at midnight Japan Standard Time. Search results contain at most ten items, with lower limits for some tools. Limits return a factual normal response rather than claiming that data retrieval succeeded. MCP sessions may be shared between conversations depending on the client.

This service searches saved observations rather than querying YouTube on demand. It does not cover every YouTube stream. Current-live results reflect observations from the past two hours. VTuber game records describe observed activity, and missing records do not establish that a creator has never played a game. Introductions are limited to 400 characters when available. Source timestamps, coverage limits, and missing-data notes accompany results. Defined tool arguments and client information are logged and aggregated for service improvement as described in the privacy policy.
