MCP: your assistant edits the video itself, for free

Over the Slicer MCP server, your AI assistant now edits the video — just like you do in the app with Edit it myself. Connect any client that supports MCP, give it your materials, and it builds the video with editor commands: cuts, hook, titles, plaques, zooms, emoji, transitions, colour, music, caption style. All of it is free.

What changed#

• create_project creates a project without the AI director by default (mode: "manual"): free, with no price and no confirmation; the materials go onto the timeline in order.
• Reading the video (get_transcript), edits with the whole operation catalog (edit_project), style (set_style), auto colour (auto_color), export and publishing (export_video) are free.
• New tools transcribe_speech and get_transcribe_jobs — captions from speech for such a project: at cost per minute of sound, in the background.
• The make_reel prompt follows the free path: a project without the AI director → captions from speech with the price, if the materials contain speech → edits → export.

What's paid#

Only Slicer's own AI features spend tokens, and each one names its price first — the assistant starts it only after you agree:

• an AI montage by the Slicer director — create_project with mode: "ai", remount_project, retry_project; the assistant offers it only if you ask for it;
• captions from speech — transcribe_speech;
• the Slicer AI assistant — ask_assistant;
• caption translation — translate_captions.

If your client called create_project without mode and expected a montage price, pass mode: "ai" explicitly. The REST API hasn't changed: the default mode of POST /v1/projects is still ai.
