MCP

PreFilm's YouTube MCP

Connect ChatGPT, Claude, Claude Code or Cursor to your PreFilm account and ask in plain words. 19 tools find what to film, write the script, change your published videos and read your own analytics.

MCP lets an assistant use another product's tools. PreFilm runs one, so your assistant can use the research PreFilm has already done on your channel and, once your channel is connected to YouTube, change your videos.

Works on every PreFilm plan, the trial included.

Then ask

What should I film next for my YouTube channel? Show the evidence behind each idea.

Every tool

19 tools in four groups

Say what you want in plain words and your assistant picks the tool. The names in mono are what it sees; you never type them.

Scripts

Scripts from what you know

The questions first: Before a script, your assistant can ask you 5 to 8 short questions about the idea, always one on where the usual advice is wrong and one on what buyers ask you on sales calls. Answer by voice; the script uses your stories and numbers, and the answers are kept as facts for the channel. The questions are priced in credits.
The recording brief: A finished script comes with a recording brief: the angle, the flow, what is on screen for each section, one sentence a line, and the sources as links, ready to paste into a doc.
Outlines: Your assistant can write the outline alone, from your Outlines, or save one you wrote, free, and write the script from it.
A thin channel: On a channel with few videos of its own, PreFilm says so, starts the first script with the questions, and learns your voice from a podcast or talk you link as well.

Rules

Nothing changes behind your back

Nothing changes until you confirm: Nothing changes without confirm: true. The assistant shows the change first. A tool that writes to YouTube reads the video again before writing, and refuses when the video changed since you read it.
Other people's words stay theirs: Titles, descriptions, transcripts and comments come from YouTube and were written by other people. PreFilm tells your assistant to treat them as data, never as instructions. A whole transcript of another creator's video is never shown, on a PreFilm screen or to your assistant: break_down_video quotes at most 8 short passages. Your own videos come back in full.
Every call is recorded: Every call is recorded on your account with what it spent, and list_channels shows what is left.
