Est-ce que com.powmcp/caption-file-check est sûr ?

Au dernier audit MCP Hub, le serveur MCP « com.powmcp/caption-file-check » est classé « Non encore testé ». Référencé dans l'annuaire. Seul le pentest comportemental fait foi, et il n'a pas encore été exécuté sur ce serveur. Le verdict est réévalué en continu ; consultez la fiche pour l'état à jour.

Méthode : MCP Hub analyse la description de chaque outil (couche 1) et, pour le verdict fort, exécute le serveur dans une micro-VM isolée avec leurres et réseau bloqué (couche 2). On publie des noms et des compteurs, jamais le contenu brut renvoyé par un outil.

• caption_check≈ 3006 tokens

  Preflight one caption or subtitle file before delivery. Attach a WebVTT (.vtt), SRT (.srt), or TTML/IMSC (.ttml/.xml) caption file in chat or give a publicly fetchable URL and it downloads the artifact under an SSRF-guarded, 2 MB-capped fetch, detects the format by content and the byte encoding and BOM, then parses it with the real spec engine (the WebVTT spec parser, a dedicated SRT parser, or the imscJS TTML/IMSC profile engine) and returns deterministic evidence: pass/fail, cue count, structural spec and IMSC profile-conformance errors, overlapping / negative / out-of-order / empty cues, per-line length, and per-cue and summary reading speed (CPS) against a named platform profile (netflix-adult-20, netflix-children-17, youtube, ebu-tt). It reports only source-file conformance, timing, encoding, and reading-speed facts against a dated profile. It does not judge translation quality, transcription accuracy, or synchronization against the video. An arbitrary XML or text file that is not a caption track returns an explicit unsupported-format error. Fetching and parsing a full-length track can take up to 60 seconds. WebVTT limitation: the parser drops payload-less cues; cue counts, indices, timing checks and comparisons cover retained cues only, not those omitted cues.

  Paramètres

  • url · string · optionnel
    A publicly fetchable HTTP(S) URL of a WebVTT, SRT, or TTML/IMSC caption file, detected by content not extension. Provide either this or an attached file, never both. Query strings are allowed but never logged. Pasted caption bodies, data URLs, FTP/SFTP, and URLs needing credentials, headers, or cookies are not supported. STRICT RULE: Caption check failed — provide either a caption URL or an attached caption file, not both STRICT RULE: Caption check failed — provide a public caption URL or attach the caption file
  • file · object · optionnel
    A caption file attached in chat (WebVTT, SRT, or TTML/IMSC), detected by content not extension. Provide either this or url, never both.
  • profile · ? · optionnel
    Named reading-speed profile to judge CPS and line length against. netflix-adult-20 (default, 20 CPS) and netflix-children-17 (17 CPS) are spec-backed; youtube and ebu-tt are advisory ~17 CPS heuristics.

• caption_compare≈ 3364 tokens

  Compare exactly two caption or subtitle files under identical bounded checks: an original versus its translated track, before versus after a timing fix, or a format migration. Attach two WebVTT, SRT, or TTML/IMSC caption files in chat or give two publicly fetchable URLs and it runs the same SSRF-guarded, 2 MB-capped preflight as caption_check on each, then aligns them by cue index and reports side-by-side pass status, detected-format and encoding differences, the cue-count delta, timing drift and overlap differences, reading-speed (CPS) regressions, structural-error deltas, and a winner only when the measured checks separate the two. Use caption_check for a single file. It reports only source-file conformance, timing, encoding, and reading-speed facts against a dated profile: never translation quality, transcription accuracy, or sync against the video. Fetching and parsing two live files can take up to 60 seconds. WebVTT limitation: the parser drops payload-less cues; cue counts, indices, timing checks and comparisons cover retained cues only, not those omitted cues.
