Palmier Pro: AI Video Editor Built for macOS
/palmier-pro
Palmier Pro is a macOS-native video editor with built-in generative AI and MCP server connectivity. The editor itself is free and open source; you only pay for AI generation. Reach for it if you want Claude or Codex controlling your timeline directly β skip it if you need broad platform support, since only Apple Silicon on macOS 26 runs it.
What is Palmier Pro?
Palmier Pro is a video editor built from scratch in Swift for macOS on Apple Silicon. It combines a traditional timeline editor with generative AI β you can create and edit video using Seedance, Kling, and other SOTA models directly inside the timeline. The app also exposes an MCP server so Claude, Codex, or Cursor can read your project and make edits alongside you.
Core Capabilities
- βSwift-native timeline editor built from scratch on macOS
- βGenerative AI built in β Seedance, Kling, and Nano Banana Pro models generate video and images directly on the timeline
- βMCP server exposed at localhost:19789/mcp so Claude, Codex, and Cursor can read and manipulate your project
- βAgent collaboration mode: the in-app chat and external AI clients can both work the same project simultaneously
- βEditor, MCP server, and agent chat are all open source under GPLv3
- βGenerative AI processing is closed source and requires login plus a subscription
Integrating with AI Agents
- β’Prompt an AI agent to assemble a rough cut by describing the footage you want, then refine it yourself in the timeline
- β’Use Seedance or Kling to generate B-roll clips without leaving Palmier Pro, then splice them into your edit
- β’Debug your timeline by asking Claude Code to inspect clip metadata and suggest restructuring
- β’Batch-generate title cards and transitions using in-app AI models, then keyframe them on the same track as your raw footage
- β’Collaborate with an agent in real time: one of you handles pacing while the other swaps in AI-generatedζΏδ»£ι倴
Connecting to MCP Servers
With the app running, the MCP server starts automatically at http://127.0.0.1:19789/mcp. For Claude Code: run `claude mcp add --transport http palmier-pro http://127.0.0.1:19789/mcp`. For Codex: run `codex mcp add palmier-pro --url http://127.0.0.1:19789/mcp`. For Cursor: add an entry to ~/.cursor/mcp.json with type "http" and that same URL, or use the in-app `Help β MCP Instructions β Install in Cursor` button. Claude Desktop gets a one-click install via a bundled mcpb extension under `Help β MCP Instructions β Install in Claude Desktop`.
Strengths
- βAI generation lives inside the timeline, not in a separate web app or cloud pipeline
- βMCP integration is a first-class feature, not an afterthought plugin β the server starts automatically with the app
- βThe core editor is genuinely free and open source with no login required
- βSeedance, Kling, and Nano Banana Pro are accessible without configuring API keys
- βAgents and humans share the same project state, so edits are immediately visible to both
Current Constraints
- β³Only runs on macOS 26 (Tahoe) and Apple Silicon β no Intel, no Windows, no Linux, no older macOS
- β³macOS 26 has not shipped yet, so the app cannot be run on any macOS version available today
- β³Generative AI features are closed source and subscription-gated, despite the editor itself being open source
- β³The project has a nascent community; third-party plugins and documentation are thin
- β³The readme does not disclose pricing tiers for the subscription β cost is unknown until you sign up

Common Questions
The editor and the MCP server are fully open source under GPLv3, but the generative AI processing that runs the Seedance/Kling models is closed source.
The video editor is free, requires no login, and the MCP server is also free. Palmier Pro only asks for payment when you access generative AI features.
Palmier Pro runs exclusively on macOS 26 (Tahoe) with Apple Silicon hardware. No Intel, no Windows, no Linux.
Generative AI generation does require a login and subscription. The timeline editor and MCP server work without any account.
The open source portions of Palmier Pro are licensed under GPLv3. Generative AI components are proprietary and closed source.
The problem it solves
Most video editors treat AI as a separate cloud service or plugin, forcing you to export, process, and re-import clips. Palmier Pro integrates AI generation directly into the timeline so both you and your agent can work the same project without switching contexts.
Who should try it β and who should skip
Try Palmier Pro if you are a Mac user who wants an AI agent reading and modifying your video timeline without manual export-import cycles, or if you want to experiment with models like Seedance inside a real editor. Skip it if you are on any platform other than Apple Silicon, if you need production stability, or if you cannot tolerate waiting for macOS 26 to ship before running anything.
