MCP support

The videoFn app contains an MCP server that exposes video-editing tools to MCP clients. The connector launches the broker in the installed app, where editing and rendering take place on the Mac.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

Details

From the project README

videoFn MCP

Video editor for your AI assistant. Builds, checks and renders edits on your Mac.

videoFn gives Claude, ChatGPT, Codex or any MCP client the tools to edit video on your Mac. Your assistant builds the edit, checks its own work and fixes the problems it finds. You watch the live preview, give notes in plain English and export the finished MP4.

This repository publishes the videoFn connector for Claude Desktop (videoFn.mcpb) and the metadata for the MCP Registry. The videoFn app itself is at videofn.com.

What it does

videoFn is a native video editor for Apple Silicon Macs with a built-in MCP server. You brief your AI assistant, and it uses videoFn's tools to build the edit from your footage, screen recordings, photos, music or documents.

  • It checks its own work. videoFn measures text legibility against moving backgrounds, cut pacing, speech cuts, audio and visual sync, and the exported file. The assistant fixes what the checks find.
  • You stay in control. The live preview shows the edit as it takes shape. Give notes in plain English, or change timing yourself in the editor.
  • Rendering happens on your Mac. No uploads, no render queue. Transcription, voiceover, noise reduction, subject tracking and image background removal also run on the device. Your assistant receives transcripts, measurements and the preview frames it asks for, under its provider's terms.
  • Buy it once. videoFn is free to try with a watermark on exports. One purchase removes the watermark. No account, no subscription, no credits. Your AI assistant is billed separately by its provider.

What people make with it

  • Product demos and launch videos from screen recordings
  • App Store preview videos
  • Release notes and changelog videos
  • Vertical social clips with captions from longer recordings
  • Explainers from a script, a PDF, a Word document or a spreadsheet
  • Talking-head cleanup: remove filler words and long pauses, add subtitles
  • Beat-synced edits, lyric videos, music videos from photos, YouTube intros

Example prompts

  • "Make a 30-second launch video from the screen recording in my Downloads folder. Add captions and some upbeat music."
  • "Cut the ums and long pauses from this interview and add subtitles."
  • "Turn this PDF report into a two-minute narrated explainer with animated charts."
  • "Make a vertical clip of the best 45 seconds of this podcast recording."

Requirements

  • An Apple Silicon Mac
  • The videoFn app
  • An MCP client: Claude Desktop, Claude Code, ChatGPT, OpenAI Codex or another client

Install

  1. Download videoFn from videofn.com/download and open it.
  2. On the launch screen, select Connect for your assistant.
  3. Ask your assistant for a video.

Claude Desktop only: you can also install the connector first. Download videoFn.mcpb from the latest release and open it. The connector needs the videoFn app. Until the app is installed, it tells Claude where to download it.

How the connector works

videoFn.mcpb contains a small launcher and no editor code. The launcher starts the MCP broker inside the installed videoFn app, so the connector always matches the app version you have. The broker starts the app when your assistant first needs it.

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
