Turn a recording you own into a timestamped transcript with SRT and VTT captions and clips.

MCP Server: app.openkrill/transcript-kit

The app.openkrill/transcript-kit MCP server turns a recording you own into a timestamped transcript. It produces subtitle caption outputs in SRT and VTT formats and also generates clips from the source recording.

🛠️ Key Features

Converts an owned recording into a timestamped transcript
Exports captions as SRT
Exports captions as VTT
Produces clips

🚀 Use Cases

Creating timed transcripts from recordings you own
Generating caption files for playback and distribution
Extracting clip segments derived from a recording

⚡ Developer Benefits

Consistent caption formats (SRT and VTT)
Transcript output with timestamps
Clip generation from the same input recording

⚠️ Limitations

Scope is limited to converting recordings you own

Captured live from the server via tools/list.

transcribe_media

Transcribes one audio or video file the user owns or may use into timestamped text with SRT and VTT captions. Best for: "transcribe this podcast episode", "make subtitles for my video", "what is said in this file". Returns: language, length, timestamped segments, SRT and VTT (trim with include), transcript_id, expires_at (kept 24 hours, the media is never kept), minutes left today, and library_id when the caller has no user id. Input tips: give file (an upload) or url (a public TikTok, Instagram or other social video, or a direct media link), not both. Set confirm_rights true only after the user says they own the recording or have the rights (a public social video needs none); otherwise ask. Pass library_id from an earlier answer to keep transcripts in one library. Not for: YouTube (call get_transcript), private videos, over 15 MB or 15 minutes, whole channels. Formats: mp3, m4a, mp4, wav, ogg, flac, webm. A daily allowance of minutes applies per user and in total.

Parameters7

file	object	optional	An audio or video file the user uploaded to the chat (ChatGPT fills this in). Give this or url, not both.
url	string	optional	Link to a public video on TikTok, Instagram, Facebook, X, Vimeo or another social platform (its audio is read and transcribed), or a direct link to an audio or video file, such as https://example.com/talk.mp3. Give this or file, not both. For a YouTube link call get_transcript instead.
confirm_rights	boolean	required	true, and only after the user has said they own this recording or have the rights to transcribe it. false is refused with rights_not_confirmed (ask the user first), except for a link to a public video on a social platform, which needs no statement.
title	string	optional	Name to show for the transcript (default: the file name).
language	string	optional	Spoken language as an ISO 639-1 code such as en or fr. Leave out to detect it.
include	array	optional	What to return besides the summary (default all three): timestamped segments, SRT captions, VTT captions.
library_id	string	optional	Leave out on the first transcription. Pass the library_id from an earlier transcribe_media answer, such as lib_9b6a98861ea4f54bff8f5cf1, to add this transcript to that same library, so search_transcripts finds both together.

search_transcripts

Searches the transcripts the user made in the last day for passages and repeated themes. Best for: "where did I talk about pricing", "which hooks did I open with", "what themes keep coming up". Returns: passages with transcript_id, start and end in seconds, a clock time and a snippet; repeated themes with counts; and the live transcripts. Input tips: pass query for passages; leave it out to list the transcripts and their themes. Pass library_id when transcribe_media returned one. Only the caller's own transcripts are searched (the latest 10, kept 24 hours). Not for: transcribing a file (use transcribe_media) or searching the web.

Parameters3

query	string	optional	Words or a phrase to look for, such as a topic or a hook. Leave out to list the transcripts and their repeated themes only.
limit	integer	optional	Most passages to return (default 8).
library_id	string	optional	The library_id an earlier transcribe_media answer returned, such as lib_9b6a98861ea4f54bff8f5cf1. It names the set of transcripts that call saved. Pass it when that answer had one; leave it out when it was null or absent.

suggest_clips

Suggests the best short clips in one saved transcript, as start and end times with a hook line. Best for: "find the best 60 seconds", "which parts would make good shorts". Returns: each clip's start and end in seconds and as clock times, a hook line, the text, a 0 to 100 rank score and the reasons. Input tips: pass the transcript_id from transcribe_media, and library_id when that answer had one. Optional: count (1 to 5, default 3), min_seconds (default 30) and max_seconds (default 60); keep min_seconds below max_seconds. Not for: cutting, editing or posting video; it returns text only. Scores rank clips against each other and do not predict views.

Parameters5

transcript_id	string	required	The transcript_id from transcribe_media or search_transcripts, such as tr_a6f8c87a9b2eb748.
count	integer	optional	How many clips to suggest, such as 2 (default 3).
min_seconds	integer	optional	Shortest clip in seconds, such as 10 (default 30). Keep it below max_seconds.
max_seconds	integer	optional	Longest clip in seconds, such as 20 (default 60). It must be above min_seconds; a smaller value is raised to min_seconds + 5.
library_id	string	optional	The library_id an earlier transcribe_media answer returned, such as lib_9b6a98861ea4f54bff8f5cf1. It names the set of transcripts that call saved. Pass it when that answer had one; leave it out when it was null or absent.

translate_subtitles

Translates subtitles or a saved transcript into another language and writes a dub script. Best for: "translate these subtitles to Spanish", "make a French dub script for my talk". Returns: translated SRT and VTT with the original times, and a dub script with one spoken line per segment, its start and end, max_chars and a fit of ok, tight or long (trim with include). Nothing is stored. Input tips: always pass target_lang. Give exactly one of transcript_id (with library_id when transcribe_media returned one) or subtitles, the text of an SRT or VTT file. With subtitles also pass source_lang and confirm_rights true, only after the user says they own the media or may use it. Limits: about 18,000 characters per call (about 20 minutes of speech) and a daily allowance of characters. Not for: transcribing audio; use transcribe_media first. Translation is machine output to check before publishing.

subtitles	string	optional	The full text of an SRT or WebVTT file the user owns or may use, with timing lines such as 00:00:01,000 --> 00:00:03,000. Give exactly one of transcript_id or subtitles. With subtitles, source_lang and confirm_rights true are required.
target_lang	string	required	Language to translate into, as a two-letter code such as es, fr, de, ja, ar or hi.
source_lang	string	optional	Language of the text, as a two-letter code such as en. Required with subtitles; for a transcript the detected language is used when left out.
confirm_rights	boolean	optional	true, and only after the user has said they own this recording or have the rights to translate it. Required with subtitles; false is refused with rights_not_confirmed.
include	array	optional	What to return (default all three): translated SRT captions, translated VTT captions, a dub script with one spoken line per segment.
library_id	string	optional	The library_id an earlier transcribe_media answer returned, such as lib_9b6a98861ea4f54bff8f5cf1. It names the set of transcripts that call saved. Pass it when that answer had one; leave it out when it was null or absent.

submit_feedback

Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know them, the tool name and the error text it returned. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

Parameters4

kind	string	required	need_tool: a tool you want. need_data: data a tool lacks. bug: something broke. other: anything else about the tools.
message	string	required	What you need or what broke, in plain words, at most 1000 characters. Links, email addresses and phone numbers are removed. Never include secrets or personal details.
tool	string	optional	Optional: the exact name of the tool on this server that the feedback is about, as tools/list shows it.
error	string	optional	Optional: for a failed call, the error text it returned, copied as you saw it. Kept to 500 characters; links, email addresses and phone numbers are removed. Never include secrets or personal details.
