How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

## MCP tools (5)

### `list_styles` (~65 tokens)

Lists the 10 Cuecaps caption styles, each with the id to pass as style to caption_video or studio_link, its name and how it looks. The list is fixed and needs no key. Call it when the user hasn't picked a style or asks what the styles look like.

### `studio_link` (~227 tokens)

Returns a URL to the Cuecaps studio, opened with these caption settings, for the user to finish in their browser: they drop in the video, can fix words and export there. Creates nothing and needs no key, so it works on every plan, Free included. Use it when the user wants to edit by hand, has no Creator or Pro key, or the file isn't on this machine; use caption_video to make the file directly.

Input parameters:

- `aspect` (string): Frame shape: 9:16 for TikTok, Shorts and Reels, 1:1 or 4:5 for feed posts, 16:9 for YouTube.
- `lang` (string): The spoken language. Give it for any video that isn't in English; auto lets cloud transcription detect it.
- `lines` (integer): Lines per caption.
- `position` (string): Where the captions sit in the frame.
- `style` (string): Caption style. list_styles shows how each one looks.
- `words` (integer): Words per caption; 1 shows one word at a time.

### `account_status` (~80 tokens)

Reads the Cuecaps account behind CUECAPS_API_KEY: the plan, cloud minutes left this period, the date they reset, and whether agent captioning is included. Uses no minutes. Call it before transcribe or caption_video to check the plan and minutes; with no key or an invalid key it returns an error that says how to get one.

### `transcribe` (~257 tokens)

Transcribes a local video or audio file and returns every word with its start and end time in seconds, plus the SRT text and the engine used. Writes no file: use caption_video when the user wants a captioned video, an overlay or a subtitle file. Needs a Creator or Pro key. engine "cloud" uses the plan's minutes and sends only compressed audio, deleted after transcription; "device" runs Whisper locally and uses none. Left unset, it picks cloud when the minutes left cover the file, else device.

Input parameters:

- `engine` (string): cloud: ElevenLabs Scribe on the plan's cloud minutes, strongest on music, accents and 90+ languages; the default when the minutes left cover the file. device: on-device Whisper, no minutes; the first…
- `keyterms` (array): Names and words for cloud transcription to spell your way.
- `lang` (string): The spoken language. Give it for any video that isn't in English; auto lets cloud transcription detect it.
- `path` (string, required): Absolute path to the video or audio file: MP4, MOV, WebM, MP3, WAV, M4A or another format the studio opens.

### `caption_video` (~562 tokens)

Captions a local video or audio file with the Cuecaps studio's renderer in headless Chrome or Edge and writes <name>.captions.<ext> next to it, never replacing a file: an MP4 with the captions burned in, a transparent MOV or WebM overlay, or SRT or VTT subtitles. Returns the file, its duration in seconds, the engine, the cloud minutes used and a studio link to fine-tune words and style. Needs a Creator or Pro key; 1440p and 4K need Pro. Transcription works as in transcribe, and the video never leaves this machine. Use transcribe when only the words are needed, and studio_link when the user wants to edit by hand or has no key.

Input parameters:

- `aspect` (string): Frame shape: 9:16 for TikTok, Shorts and Reels, 1:1 or 4:5 for feed posts, 16:9 for YouTube.
- `engine` (string): cloud: ElevenLabs Scribe on the plan's cloud minutes, strongest on music, accents and 90+ languages; the default when the minutes left cover the file. device: on-device Whisper, no minutes; the first…
- `fps` (integer): Frames per second.
- `keyterms` (array): Names and words for cloud transcription to spell your way.
- `lang` (string): The spoken language. Give it for any video that isn't in English; auto lets cloud transcription detect it.
- `lines` (integer): Lines per caption.
- `out_path` (string): Absolute path to write to instead of <name>.captions.<ext> next to the input, ending in .mp4, .mov, .webm, .srt or .vtt; its extension sets output. An existing file is never replaced: -2, -3 and so o…
- `output` (string): mp4 with the captions burned in, mov or webm as a transparent captions-only overlay, or srt or vtt subtitles. Defaults to out_path's extension when out_path is given, else mp4.
- `path` (string, required): Absolute path to the video or audio file: MP4, MOV, WebM, MP3, WAV, M4A or another format the studio opens.
- `position` (string): Where the captions sit in the frame.
- `resolution` (string): Short side of the video. 1440p and 4k come with Pro.
- `style` (string): Caption style. list_styles shows how each one looks.
- `words` (integer): Words per caption; 1 shows one word at a time.
