openclip

Submit the video URL with submit_video, poll get_video_status until completed, then call list_clips to get moments ranked by virality_score. Optionally render any moment with a caption preset using render_clip.

Upload the file with create_upload, PUT the bytes to the upload URL, then call transcribe and poll get_tool_job_status. It returns JSON, SRT, and VTT outputs with speaker diarization, needing only an account, no subscription.

Transcription, video editing (trim, crop, resize, compress, mute), format conversion, thumbnail extraction, image editing, and background removal are free with an account. The clipping pipeline and caption rendering require a subscription and credits.

submit_video always queues successfully; failures surface later in get_video_status. A failed status usually means no active subscription, pending_credits means the team is out of credits, and download_failed means the source URL could not be fetched.

Yes, OAuth one-click is the primary path: add https://openclip.app/mcp to your client and sign in with your OpenClip account. Header-only clients can instead use a manually generated MCP token against the /mcp/key endpoint as a Bearer header.

All processing is asynchronous, so you must poll job status rather than expect instant results. The API has no projects or folders concept, free tools have daily rate limits and per-file size caps, and free accounts get one UGC generation per day.
