Palmier Pro is an open-source macOS video editor designed for AI-assisted workflows. It integrates with Claude, Cursor, and Codex via MCP protocol, allowing AI agents to collaborate on video projects. The core editor is free; generative AI features (video/image generation) require login and subscription.

What palmier-pro is
Swift-native macOS video editor exposing an MCP HTTP server (port 19789) for agent integration. Supports generative models (Seedance, Kling, Nano Banana Pro) and timeline-based AI collaboration. Requires macOS 26 (Tahoe) on Apple Silicon; closed-source AI processing layer.

Best use cases
Implementation considerations
- Requires macOS 26 (Tahoe) and Apple Silicon; verify target machine meets specifications before deployment.
- MCP server runs locally on port 19789; ensure firewall/network policies permit localhost HTTP connections from Claude/Cursor/Codex.
- Generative AI features depend on external API subscription (Seedance, Kling, Nano Banana); budget for API costs and latency.
- GPLv3 license means any modifications or derivative works must remain open-source; internal forks trigger disclosure obligations.
- Project is ~3 months old; monitor GitHub for breaking changes, performance regressions, or API shifts before integrating into critical workflows.
When to avoid it — and what to weigh
- Cross-Platform Requirement — macOS 26 (Tahoe) Apple Silicon only. If you need Windows, Linux, or Intel Mac support, this is not suitable.
- Self-Contained Offline Use — Generative AI features require login and subscription; core editor is free but full feature set ties to Palmier's backend service.
- Production-Grade Enterprise Video Pipeline — Project is under 4 months old (created April 2026). Stability, codec support, and color-grading depth are not yet production-proven at broadcast scale.
- No GPL-Compatible Codebase Requirement — GPLv3 copyleft may conflict with proprietary software integration; derivative works must also be GPLv3.
License & commercial use
GPLv3 (GNU General Public License v3.0). Core video editor and MCP server are open-source under copyleft; generative AI processing is proprietary/closed. Any derivative work, modification, or bundling must comply with GPLv3 terms (source availability, same license).
GPLv3 is not a permissive license. Commercial use of the open-source editor components is allowed, but you must: (1) provide source code to end-users, (2) license any changes under GPLv3, (3) disclose the license clearly. Generative AI features are proprietary and subject to Palmier's separate terms (subscription required). Requires legal review before commercial redistribution or bundling.

MCP server exposes HTTP endpoint on localhost without TLS; suitable for dev/local environments but not for multi-user or remote scenarios. Generative AI features require login/API keys; data handling practices unknown (Requires review of Palmier's privacy policy). No security audit data provided. Early-stage project has not published security advisories or vulnerability disclosure policy.
Alternatives to consider
Adobe Premiere Pro + AI plugins
Mature, cross-platform, enterprise-grade, but proprietary and costly; does not natively expose MCP for agent control.
CapCut (free tier)
Lightweight, free, AI-assisted editing, but closed-source, mobile-first, and no open MCP integration or agent workflows.
DaVinci Resolve (Free/Studio)
Cross-platform, powerful color/audio, free option, but limited AI generative features and no native agent/MCP support.
