Palmier Pro: GPLv3 macOS Video Editor Ships an MCP Server So Claude, Codex and Cursor Can Edit the Timeline
Palmier Pro is an open-source Swift video editor at 12,000+ stars and 887 forks that puts generative models — Seedance, Kling, Nano Banana Pro — directly in the timeline and exposes an MCP server letting Claude, Codex and Cursor collaborate on projects alongside an in-app agent. The editor is free with no login; generative features require subscription. It requires macOS 26 Tahoe on Apple Silicon only. The 186-point Show HN is a concrete instance of a pattern worth watching: desktop creative tools shipping MCP surfaces so coding agents can drive non-code applications.
