Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 460 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-06-18, serverInfo.name yank.info.

  • Pass
    Lists tools

    tools/list returned 7 tools.

  • Pass
    Current protocol

    Negotiated 2025-06-18. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 460 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 460 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Fail
    Parameters documented

    7 of 10 parameters have a description (70%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-09-27T00:41:28.041999Z, within 180 days.

check_memory

check_quote over a batch, for auditing what an agent wrote down earlier. Give it up to 10 remembered claims, each with the source it is attributed to, and it returns the same verdict and receipt for every one: FOUND, CLOSE MATCH, DISTILLED MATCH, NOT FOUND or CAN'T ESTABLISH, with where, the speaker and the class of that claim, the passage, which representation was read and how much of it, and when. Reach for it when a note, a memory store or a shared workspace has accumulated claims nobody re-checked, and you want the ones no source supports. The summary counts verdicts and lists the claims that came back NOT FOUND; it is deliberately not a score, a percentage or a trust rating, because a NOT FOUND is bounded to the representation Yank read and is never a claim that the words were not said. A claim whose source is audio Yank would have to transcribe returns CAN'T ESTABLISH rather than being paid for. No model is consulted anywhere in this: every verdict resolves against the representation itself, and none of them is a judgement on whether a claim is true.

Discovered
check_quote

Yank Check: a statement and the source it is supposed to come from, in; a verdict and a receipt, out. FOUND (the words are in the representation Yank inspected), CLOSE MATCH (substantially the same wording, with the difference shown), DISTILLED MATCH (a passage shares most of the statement's content words but not its literal words; shared words can say the opposite, so read the passage), NOT FOUND (Yank inspected an adequate representation and could not find support), or CAN'T ESTABLISH (Yank could not obtain or inspect enough evidence; the reason says why). With where (a moment for media, the publisher's page opened on the exact words for an article), speaker with the class of that claim (file-stated, representation-stated, not-established), the passage around it, which representation was read (captions, transcript, article text, filing, document) and how much of it (inspected: words, duration, and sha256, the fingerprint of the exact text read), the checker's version (checker), and when. A NOT FOUND is a bounded claim scoped to the representation read, never a claim that the words were not said; a CLOSE MATCH lists the words that differ (difference.tokens), never a similarity number; every verdict carries one plain sentence (finding). No model is consulted: the verdict resolves against the representation itself. Sources Yank already holds check immediately; an article, a public PDF (located by page) or a captioned video is read for the check; audio that would need transcribing is not spent on here and returns CAN'T ESTABLISH with acquisition_required, so yank it first. None of the verdicts is a judgement on whether the statement is true.

Discovered
get_lines_for_url

Ask before you extract: everything yank.info already holds from one source URL. Any form of the link works (a youtu.be short link with a timestamp, a watch URL with a playlist, an article with tracking parameters, an Apple Podcasts or Overcast episode link); equivalent URLs return the same answer. Returns real counts (yanks, lines, verbatim lines) and, for up to five yanks, every line with its verbatim flag, timestamp, moment link, context and permanent card URL. Zero yanks is an answer, not an error. Reads the library only; never fetches the source.

Discovered
get_yank

Fetch a yank (five extracted lines from one source) by its slug, the last path segment of a yank.info/y/<slug> URL. Includes every line's verbatim flag, timestamp, moment link, surrounding context, permanent card URL, share image, plus the whole yank as Markdown.

Discovered
recent_yanks

The newest yanks in the library, one card each (rank-1 line, author, source type, URL).

Discovered
search_lines

Full-text search across every line yank.info has ever extracted. Returns quotable lines with a verbatim flag (true = literal substring of the source transcript; false = labeled paraphrase), the speaker/author, the source, a timestamp and a moment link where the source is a video, and the permanent card URL to cite. Supports quoted phrases and a leading minus to exclude a word.

Discovered
search_transcripts

Full-text search inside the whole transcripts of every podcast and video yank.info has yanked, not only their five lines (§10.424). Returns moments: the source, where in it (startSeconds, endSeconds), the words around the match (snippet, the match between « and »), a moment link that opens the source at that second, and yankThisPartUrl, which yanks the few minutes around it. The words are a machine transcript (representation: transcript), not a checked line: to quote one, yank that part or use check_quote. Supports quoted phrases and a leading minus.
