• capture_animation

  kernelcad

  Use this when you need to render a script's animation timeline to a video. Capture a kernelCAD script's animationView({...}) timeline to an MP4 (ffmpeg) or a PNG frame sequence, verifying the sampled poses for part interference. FILE ONLY: pass { file } (a .kcad.ts path) — there is no { code } mode, because the capture engine renders from a file on disk (its relative lib.fromSTEP imports resolve against the script directory). MP4 by default; pass { frames_dir } to write frame-0000.png... and skip ffmpeg entirely (mutually exclusive with output_path). Animation-pose interference verification runs by default (keyframe times + segment midpoints) BEFORE any browser/ffmpeg cost; { no_verify: true } skips it and { verify_every: n } additionally samples every n-th frame time. Pass { focus } or { hide } (arrays of feature ids or assembly part names, mutually exclusive) to isolate parts in the rendered frames — same semantics as `kernelcad render --focus/--hide`; visibility is render-only and does NOT affect the pose verification. Collisions DO NOT fail the call — the artifact is still written as evidence with ok: true; read verified: false + the collisions[] array. ENVIRONMENT REQUIREMENT (identical to `kernelcad render`): capture drives a headless browser against a running studio dev server reachable at http://localhost:5173 (or the VITE_PORT override); there is no bundled-static serving mode yet, so the same dev-server precondition applies in a production MCP install. Returns { ok, output_path, frame_count, duration_ms, fps, verified, verify_skipped?, collisions: [{ t_ms, a, b, volume_mm3 }], diagnostics }.

• confirm_upload

  FFmpeg Micro

  Step 2 of the direct-upload flow. Call after PUTting the file bytes to the URL returned by `request_upload_url`. Returns the final `gs://...` `fileUrl` plus probe metadata (duration, format, codecs). Use the `fileUrl` directly as a `media_url` for `transcribe_audio` or as an `inputs[].url` for `transcode_video`.

  Connector

• transcode_and_wait

  FFmpeg Micro

  One-shot convenience tool: creates a transcode job, polls until it reaches a terminal state (completed/failed/cancelled) or the timeout expires, and returns the final job plus a signed download URL if completed. Use this when you want the full transcode in one step without managing polling yourself.

  Connector

• get_transcribe

  FFmpeg Micro

  Fetch the current state of a single transcribe job by ID, including status (queued/processing/completed/failed) and `output_url` when completed. Mirrors `get_transcode` but for SRT generation jobs created via `transcribe_audio`.

  Connector

• get_transcribe_download

  FFmpeg Micro

  Generate a short-lived (10 minute) signed HTTPS URL for a completed transcribe job's SRT file. The job must be in `completed` status. The returned URL can be dropped directly into a transcode's `subtitles='<url>'` filter to burn captions into a video.

  Connector

• request_upload_url

  FFmpeg Micro

  Step 1 of the direct-upload flow. Returns a short-lived presigned HTTPS URL that the caller PUTs the file bytes to (with the same Content-Type that was passed in). After the PUT succeeds, call `confirm_upload` with the same filename and fileSize to receive the final `gs://` URL for use as a transcode/transcribe input. The presigned URL expires in ~15 minutes.

  Connector

• get_download_url

  FFmpeg Micro

  Generate a short-lived (10 minute) signed HTTPS URL for a completed transcode's output file. The job must be in `completed` status. Use this instead of the `output_url` field on the job object, which is a `gs://` URL that HTTP clients cannot fetch directly.

  Connector

• transcode_video

  FFmpeg Micro

  Create a video transcode job on FFmpeg Micro. Accepts one or more input videos (gs:// or https://) and an output format. Returns immediately with a queued job — use `get_transcode`, `list_transcodes`, or `transcode_and_wait` to follow progress.

  Connector

• transcribe_audio

  FFmpeg Micro

  Generate an SRT subtitle file from an audio or video URL using Whisper. Returns a queued job envelope immediately — poll with `get_transcribe` until status is `completed`, then fetch the signed SRT URL with `get_transcribe_download`. The SRT URL can be dropped directly into a transcode's `subtitles='<url>'` filter to burn captions into a video.

  Connector

• cancel_transcode

  FFmpeg Micro

  Cancel a queued or processing transcode job. Jobs that are already completed, failed, or cancelled cannot be cancelled and return an error.

  Connector

• list_transcodes

  FFmpeg Micro

  List transcode jobs for the authenticated account, with optional filters for status and time range. Paginated (default page 1, limit 20).

  Connector

• get_transcode

  FFmpeg Micro

  Fetch the current state of a single transcode job by ID, including status (queued/processing/completed/failed) and `output_url` when completed.
