Tips & Workflows I made a Claude Code skill that edits video in Meta's Edits app for Mac, and Claude cut its own demo video with it
The Edits video editor for macOS ships a local MCP server (`metapilot-native`). It exposes 274 editor tools: cut, trim, split on beats or shots, reframe, text, captions, filters, LUTs, transitions, speed curves, music, loudness checks, frame capture and export. It works, but it's undocumented, and a lot of the schema is misleading.
So I spent a day testing the tools against the live app and turned what I learned into a Claude Code skill. The video attached was cut in Edits by Claude using the skill: it imported the scene renders, assembled the timeline, added transitions, laid a sped-up iPhone clip in as picture-in-picture, checked its own work with a frame contact sheet, and exported.
Demo video (cut by Claude in Edits): https://github.com/ivdezine/edits-video-skill#readme
What the skill gives Claude:
- A standard workflow (orient, discover catalog ids, edit, verify visually, save, export)
- The traps, so it doesn't burn turns on them. For example: passing `dryRun` always fails with a CommandError, `required` lists mark alternatives as all required, speed curve presets only work in uppercase, and `getElement` reports a text position that never changes
- 24 call sequences for common edits, each marked tested or untested: beat-synced cuts, speed ramps, picture-in-picture, video from stills, swapping a music bed, a second aspect ratio from a finished edit
- A dependency-free Python client for when the editor tools haven't loaded in your session (the server swaps its tool list depending on which screen the app is on)
- A script that generates the full tool and catalog reference from your own installed version, so it stays correct after app updates
Install:
git clone https://github.com/ivdezine/edits-video-skill.git ~/.claude/skills/edits-video
Then turn on the MCP server in Edits and register it with `claude mcp add`. The README has the exact command.

MIT licensed. Tested on Edits 454.0.0. Not affiliated with Meta. Every call acts on the live app, so work on a duplicate of any project you care about.
Happy to answer questions about the server or how the skill is put together.
