# Kdenlive MCP

Local-first video editing through the Model Context Protocol. Kdenlive MCP keeps
a versioned JSON project as the source of truth, applies revision-checked timeline
edits, compiles deterministic MLT, queues renders, generates previews, and verifies
outputs using the Kdenlive/MLT and FFmpeg installation already on your computer.

> This is a fork of [AMMIROSOH/Kdenlive-mcp](https://github.com/AMMIROSOH/Kdenlive-mcp)
> that uses Bun instead of pnpm for dependency management and scripts. The server
> itself still runs on Node.js.

> Public preview: Milestones 0-4, 6, and 7 are implemented. Local AI analysis
> (Milestone 5) remains planned and unavailable.

## What works

- Canonical projects with atomic revisions, checkpoints, undo, and redo.
- Media ingest with allowed-root containment and managed/external modes.
- Clip placement, linked A/V, ripple edits, properties, keyframes, effects,
  transitions, text, captions, and markers.
- Every Kdenlive video and audio effect (blur, keying and masks, transform,
  stylize, audio EQ and dynamics, and more) on clips, tracks, and the master
  output, with effect zones. See the [effects guide](docs/effects.md).
- Color correction and grading with all of Kdenlive's Color and Image Correction
  effects (lift/gamma/gain, curves, levels, white balance, 3D LUTs, HSL, and more)
  on clips, tracks, and the master output, plus color scopes and measurements.
  See the [color grading guide](docs/color-grading.md).
- Durable preview/export jobs, progress, cancellation, restart recovery, and
  bounded artifacts.
- Output duration, stream, A/V sync, loudness, clipping, black, and freeze checks.
- MCP over stdio or authenticated loopback Streamable HTTP.
- Automatic Kdenlive/MLT/FFmpeg discovery and an actionable doctor command.
- Editable Kdenlive 26.04.x and OTIO 0.18.1 export, plus reviewed import plans.
- Versioned editing recipes and advisory, durable timeline diagnostics.

## Quick start

Requirements: Node.js 22+, Bun 1.3+, and Kdenlive or separate MLT/FFmpeg tools.

Powershell:

```powershell
git clone https://github.com/felixkarevo/kdenlive-mcp.git
cd kdenlive-mcp
Set-ExecutionPolicy -Scope Process Bypass
.\scripts\install.ps1 -AddToPath
kdenlive-mcp --doctor
```

Linux:

```sh
git clone https://github.com/felixkarevo/kdenlive-mcp.git
cd kdenlive-mcp
./scripts/install.sh
~/.local/share/kdenlive-mcp/kdenlive-mcp-*/kdenlive-mcp --doctor
```

Then add the stdio command to your MCP client with an absolute allowed root:

```text
kdenlive-mcp --root /path/to/video-workspace --client-id my-mcp-client
```

See the complete [installation and client configuration guide](INSTALL.md).

## Safety model

- Files are limited to configured roots; symlink/traversal escapes are rejected.
- Mutations require the exact current revision and remain undoable per client.
- Render processes use argument arrays, no shell, bounded output/time, and a
  restricted environment.
- HTTP binds only to loopback and requires a generated bearer token.
- Kdenlive, MLT, and FFmpeg binaries are not redistributed by this repository.

Read the [threat model](docs/threat-model.md) and [security policy](SECURITY.md)
before exposing the server to additional software.
