  2. Add the serverRun this once in a terminal:
    claude mcp add --transport http null-studio http://127.0.0.1:4350/mcp
  3. Ask for the editIn Claude Code, say what you want. It calls Null’s tools and you watch the timeline change.
Claude Code
Tighten my podcast clip: cut the pauses, add captions 3 words at a time, and put a “Follow for part 2” button at the end.
cut_dead_air 7 pauses · 1:12 → 0:58 set_captions 41 cards · 3 words add_motion CTA at 0:54 get_frame checked the ending
Done. The clip is 14 seconds shorter, captions are on, and the button lands in the last four seconds. I checked the final frame and the button isn’t covering the captions. Want me to export it?
A real session: Claude Code drives the open editor, and each call lands in Null’s agent panel.

Questions about MCP

What is MCP?

The Model Context Protocol is an open standard that lets AI apps use outside tools. Null Studio ships an MCP server, so any app that supports MCP can read your project and edit it with Null’s tools.

Which AI apps work?

Claude Code, Claude Desktop, Codex, and Cursor, plus any other MCP client that can reach a local server over Streamable HTTP or stdio.

Do I need an API key?

No. Your AI app uses the account you already have, and Null never sees your credentials. Null Studio only accepts connections from your own computer.

Does my footage get uploaded?

No. Your video stays on your computer. Your AI sees the transcript, project details, and any frames it asks for, the same way it sees anything else you share in the chat.

Can it wreck my edit?

Every tool call is one step in Null’s undo history and shows in the agent panel as it happens. Press Ctrl+Z, or ask your AI to undo.
