Project overview
Palmier Pro is an open-source macOS video editor written in Swift, designed from the ground up so that a human and an AI agent can work on the same timeline together. It requires macOS 26 (Tahoe) on Apple Silicon and ships as a downloadable .dmg with no login required for the core editor.
The project is backed by Y Combinator's S24 batch and positions itself as a Premiere Pro-class editor with AI woven into the workflow rather than bolted on. The editor itself, the MCP server, and the in-app agent chat are open source under GPLv3. The generative AI processing is closed source and gated behind a subscription.
What makes Palmier Pro notable is its MCP-first architecture: while the app is running it exposes a local HTTP MCP endpoint, letting tools like Claude Code, Claude Desktop, Codex, and Cursor directly manipulate the timeline. This turns the editor into a controllable surface for agent-driven video production.
Why it is trending now
- 904 stars in the period, reflecting fast developer interest in agent-controllable creative tools
- Native Swift implementation targeting the latest macOS Tahoe release on Apple Silicon
- Built-in access to SOTA generative models such as Seedance, Kling, and Nano Banana Pro directly inside the timeline
- MCP integration with Claude Code, Claude Desktop, Codex, and Cursor — the exact agent stack developers already use
- Y Combinator S24 backing gives the project visibility and credibility in the AI tooling space
Problem it solves
- Traditional video editors treat AI as an afterthought, adding plugins or export menus rather than true collaborative editing
- Creators using AI coding agents have no native way to drive a timeline-based editor programmatically
- Switching between a generative model playground and a separate NLE breaks creative flow
- Most AI video tooling is browser-based and cloud-only, with no local timeline or project ownership
How it works
- Download the PalmierPro.dmg for macOS 26 Tahoe on Apple Silicon — the editor opens with no login required
- Launch the app; it automatically exposes a local MCP server at http://127.0.0.1:19789/mcp
- Connect an MCP client such as Claude Code, Claude Desktop, Codex, or Cursor using the provided one-click installer or manual JSON config
- Use the connected agent or the in-app agent chat to generate, edit, and manipulate clips on the shared timeline
- For generative AI features (Seedance, Kling, Nano Banana Pro), log in and subscribe; the editor and MCP server remain free to use
Agent Integration via MCP
- Local HTTP MCP server at http://127.0.0.1:19789/mcp is live whenever the app is open
- Claude Code: `claude mcp add --transport http palmier-pro http://127.0.0.1:19789/mcp`
- Codex: `codex mcp add palmier-pro --url http://127.0.0.1:19789/mcp`
- Cursor: one-click install via Help > MCP Instructions, or manual ~/.cursor/mcp.json entry
- Claude Desktop: bundled mcpb extension for one-click install via Help menu
Built-in Generative AI
- Access SOTA models — Seedance, Kling, Nano Banana Pro — directly inside the timeline editor
- Generate videos and images without leaving the project workspace
- Generative processing is closed source and requires login plus a subscription
- The open-source editor remains free and usable without any generative features
Swift-Native Timeline Editor
Palmier Pro is built from scratch in Swift, with the stated north star of matching Premiere Pro's capabilities while introducing its own take on AI-native workflow integration. Development requires macOS 26+, Xcode 16+, and the Swift 6.2 toolchain.
Who should pay attention?
Good fit if
- You develop on macOS 26 Tahoe with Apple Silicon and already use Claude Code, Cursor, or Codex
- You want a free, open-source desktop editor with agent-controllable timelines
- You build AI-driven content pipelines and need a real NLE surface instead of a browser toy
- You're exploring MCP as a protocol and want a high-value creative use case
Skip for now if
- You're on Windows, Linux, or Intel Mac — the app is Apple Silicon macOS 26 only
- You need a fully open-source generative AI pipeline — those features are closed and subscription-gated
- You require an established production-grade editor with years of plugin ecosystem maturity
Risks and cautions
The editor and MCP server are open and free, but platform requirements are narrow and generative AI is closed-source with subscription gating.
- macOS 26 Tahoe on Apple Silicon only — excludes most of the market
- Generative AI processing is closed source, creating vendor lock-in for the headline features
- Early-stage project; the README acknowledges limited bandwidth to review large unsolicited PRs
- Requires familiarity with MCP configuration to unlock the agent-driven workflow
- MCP server runs locally at 127.0.0.1, limiting exposure to the local machine
- No login required for the editor and MCP server — credentials only needed for generative AI subscription
- Generative AI processing details are closed source, so data handling for those features is not publicly auditable
- Licensed under GPLv3, ensuring the open-source portions remain free and modifiable
Alternatives to compare
| Approach | When to use | Trade-off |
|---|---|---|
CapCut | You need a cross-platform editor with broad device support and no agent integration | Free tier with paid features |
Adobe Premiere Pro | You need a mature, industry-standard NLE with a deep plugin ecosystem | Subscription |
DaVinci Resolve | You want professional-grade color and editing on macOS without AI agent control | Free tier with paid Studio version |
What this trend reveals
Agent-Native Creative Workflows
Palmier Pro demonstrates how MCP can turn a desktop creative app into a controllable surface for coding agents, opening a pattern that other media tools could follow.
Try connecting Claude Code or Cursor and issuing timeline edits — if it outperforms manual editing, the pattern has legs.
Hybrid Open / Closed Licensing
The editor is GPLv3 while generative AI stays proprietary, a model that could attract contributors to the core while protecting monetizable IP.
Review which features fall on each side of the license boundary and whether the open core is sufficient for your use case without the subscription.
Apple Silicon Creative Tooling
A Swift-native editor targeting macOS 26 Tahoe taps into under-served demand for high-performance creative software on Apple Silicon.
Benchmark editor responsiveness and generative model throughput on your hardware to see if the native approach justifies the platform restriction.
RepoDaily verdict
Palmier Pro is a compelling bet on agent-native video editing — the open-source Swift editor and local MCP server are genuinely useful today on Apple Silicon, while the closed generative layer and narrow OS support define both its monetization and its limits.
