Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
account_status ~80
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
caption_video ~562
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.
| Name | Type | Req | Description |
|---|---|---|---|
| aspect | string | – | Frame shape: 9:16 for TikTok, Shorts and Reels, 1:1 or 4:5 for feed posts, 16:9 for YouTube. |

| 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 | yes | 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. |
No output schema declared.
No examples provided.
list_styles ~65
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
studio_link ~227
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.

transcribe ~257
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.
| Name | Type | Req | Description |
