_ is it live, free and safe measured by this hub
Is youtube-transcript-api live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is youtube-transcript-api free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does youtube-transcript-api have?
14 tools: list_channel_videos, list_playlist_videos, search_playlist_videos, get_transcripts_results, get_video_info, get_transcript, get_transcripts_job, get_transcripts_result, ….
Is youtube-transcript-api safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_channel_videos reads auth-required 17h ago

    List videos from a channel's Videos tab, newest first. Accepts an @handle, a UC... channel id or a channel URL. ids_only=true returns just video ids (up to 500 per page) — use it when you only need ids to fetch transcripts.

  • list_playlist_videos reads auth-required 17h ago

    List videos of a playlist in playlist order. Accepts a PL... playlist id or a URL with list=. ids_only=true returns just video ids (up to 500 per page).

  },

}
    arguments 23 lines
  • search_playlist_videos reads auth-required 9h ago

    Find videos inside a playlist by a substring of the title (case-insensitive). YouTube has no native playlist search, so this scans up to 500 playlist items. truncated=true means there may be more matches beyond the scanned window.

    mcp-tool

    {

    arguments 22 lines
  • get_transcripts_results reads auth-required 13h ago

    Read finished transcripts from a batch job, in the order submitted. Results appear as they are fetched, so this can be called before the job is done. Each entry is exactly what get_transcript returns for that video, plus its status. Page with next_page_token. Free.

    mcp-tool

  "type": "object",

}
    arguments 21 lines
  • get_video_info reads auth-required 13h ago

    Get metadata for one YouTube video (title, channel, duration, views, thumbnails) plus the list of available transcript languages, WITHOUT downloading the subtitles. Use it only when the transcript itself is not wanted. If you are going to fetch the transcript anyway, call get_transcript with video_metadata=true instead — it returns both for one credit, where these are two separate calls and two credits.

    mcp-tool

    {
  "type": "object",
  "required": [
    "id"

  },
  "additionalProperties": false
}
    arguments 13 lines
  • get_transcript reads auth-required 2h ago

    Get the transcript (subtitles) of a YouTube video. Accepts a video id or any YouTube URL. Set video_metadata=true to get the title, channel and duration in the SAME call — do not call get_video_info first, that is a second billed call for data this one already returns. format=text returns plain readable text (default, cheapest to read); format=json returns timed segments with start/duration in seconds; srt/vtt return ready subtitle file bodies and srv3 the raw YouTube XML. Prefer text unless you need timestamps or a file. Costs 1 credit.

  • get_transcripts_job reads auth-required 2h ago

    Check the progress of a batch job: status (queued/running/done/cancelled), how many videos are ready, failed and still pending. Free — polling a job you already paid for costs nothing. Read the transcripts themselves with get_transcripts_results.

    mcp-tool

  "type": "object",
  "required": [

    arguments 13 lines
  • get_transcripts_result reads auth-required 2h ago

    Read ONE video's result out of a batch job by its video id, without paging through get_transcripts_results. 404 means the job does not exist or this video has not finished yet — check get_transcripts_job before concluding anything. Free.

    mcp-tool

  • submit_transcripts_job changes data auth-required never probed

    Queue transcripts for MANY videos at once (up to 4000) and get a job_id back immediately — the work continues in the background. Use this instead of calling get_transcript in a loop for more than a handful of videos. Feed it video ids from list_channel_videos or list_playlist_videos (ids_only=true). Next: poll get_transcripts_job until status is 'done', reading finished transcripts from get_transcripts_results as they land. Costs 1 credit per video, charged on submit; duplicates are removed first. Requires a user key (sk_...).

  • cancel_transcripts_job changes data auth-required never probed

    Cancel a batch job. Credits are refunded ONLY for videos not started yet — anything already fetched stays in the results and stays paid for. Free.

  • get_credits reads auth-required never probed

    Check the remaining credit balance of the API key. Free. Use it when the user asks how many credits are left, or before submit_transcripts_job to confirm a large batch fits the balance (the batch charges 1 credit per video on submit).

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 07ffb4f6a918ecb5.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/07ffb4f6a918ecb5/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
