Overview

AI-generated overview

Lets an AI assistant drive the klo macOS video editor, editing timelines, captions, color, audio, and exports while media stays local.

What you can do
This connector exposes 83 tools for the klo native macOS video editor, covering library import, timeline assembly and ripple edits, transitions, text and captions, motion templates, color grades and LUTs, audio ducking and beat quantization, transcripts and frame capture, style profiles, and ProRes export. The agent sends semantic timeline operations and receives compact results such as timecodes, transcripts, and frames, rather than piping video bytes. Some tools generate new media such as music, sound effects, voiceover, or video.
When to use it
Use it when you want a coding agent to edit video on a Mac: cutting filler words, captioning, assembling takes from a transcript, grading to a reference, or exporting client deliverables. It suits editors who already use klo and want agent-driven timeline work without uploading footage.
Requirements
macOS 13 or later with the klo app installed and the connection enabled in klo Settings, plus a connection token supplied as the KLO_MCP_TOKEN environment variable or an Authorization bearer header. The server runs locally over stdio or a local HTTP endpoint on 127.0.0.1; the port may differ from the default. A klo account is needed for credit-based generation tools.
Before you install
The KLO_MCP_TOKEN is a secret that grants control of the editor; rotate it from klo settings if exposed. Tools write to and modify projects, including deleting clips and exporting files. Generation tools for music, voiceover, and video spend klo account credits, though the agent is told the price first. Voice cloning tools are consent-gated in the app. Media stays on the Mac, but some tools such as web search and delegated research reach outside.

Installation

In SourceWeft

  1. Open Klo Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

[klo, the native Mac video editor you talk to]

klo-mcp: the video editing MCP server

[npm] [license] [platform] [site]

Give your coding agent a real video editor.

klo is a native macOS video editor you talk to. This is its MCP server: Claude Code, Codex, Cursor, Claude Desktop, or any MCP client can drive the whole timeline, with 83 tools, while your footage never leaves your Mac.

  • A real editor underneath. Not an ffmpeg wrapper: ripple edits, word-gap cuts, karaoke captions, color grades, generated music, ProRes export. Every edit lands on a normal timeline a human can open and adjust.
  • Media stays local. Piping video bytes through a text protocol fails (base64 versus context windows). klo holds the media on your machine and exposes semantic timeline operations instead. The agent sends intent and gets back compact results: timecodes, transcripts, real frames when it needs to look.
  • Local, token-gated, off by default. The server listens on 127.0.0.1 only, requires a bearer token, and does nothing until you turn it on in klo's settings.

Quickstart

  1. Get klo for Mac (free tier included, macOS 13+).
  2. In klo: Settings → Connections, turn the connection on, and copy the URL and token it shows.
  3. Connect your client:

Claude Desktop (one click)

Download klo.mcpb and open it. Done.

Claude Code

sh
claude mcp add --transport http klo http://127.0.0.1:41720/mcp \  --header "Authorization: Bearer YOUR_TOKEN"

Use the exact URL shown in klo's settings (the port can differ if 41720 is taken).

Cursor, Codex, and other MCP clients

Either point the client at the HTTP endpoint above, or use this package as a stdio server:

json
{  "mcpServers": {    "klo": {      "command": "npx",      "args": ["-y", "klo-mcp"],      "env": { "KLO_MCP_TOKEN": "YOUR_TOKEN" }    }  }}

What your agent can do

Ask in plain language, or call tools directly. A few real prompts:

  • "Cut the boring parts and the filler words, then caption it word by word."
  • "Watch this folder and turn every new recording into a captioned vertical clip."
  • "Pick the best take of each line from the transcript and assemble the cut."
  • "Grade everything to match this reference and export ProRes for the client."

Pricing

Driving the timeline over MCP is free: your agent brings its own model. The handful of tools that generate new media (music, voiceover, generated shots) use your klo account's credits, and the agent is told the price before it spends. New accounts get 10 free asks.

Security notes

  • Listens on 127.0.0.1 only. Nothing is exposed to the network.
  • Bearer token auth with constant-time comparison. Rotate the token from klo's settings anytime.
  • Off by default. If klo is running but the connection is off, the server tells your agent exactly that.
  • Voice cloning tools are consent-gated in the app.

Troubleshooting

"klo is running but is not accepting connections": turn the bridge on in klo → Settings → Connections, then copy the token into KLO_MCP_TOKEN (or the Authorization header for HTTP).

Port differs from 41720: klo falls back to an ephemeral port if the preferred one is taken. Always trust the URL shown in Settings.

About

This package is the thin connector; the editor itself is klo. The connector mirrors the copy bundled inside the app, and its major.minor version tracks the app release it shipped with.

FAQ

Can Claude Code edit videos? With klo installed, yes. Claude Code connects to this server and gains cutting, captions, grading, generated music and voiceover, and ProRes export on a real timeline. See what agentic video editing is.

Is this an ffmpeg wrapper? No. Tools operate on klo's timeline (ripple edits, word-gap cuts, undo), and nothing is re-encoded between steps. Why that design.

Does my footage get uploaded? No. Media stays on the Mac; the server exchanges timeline operations and compact results. Details in klo's privacy policy.

What does it cost? Driving the timeline is free with your own model. Generation tools use klo account credits. Pricing.
