After Effects MCP (HeroicSwan)
Production-minded AE MCP server with a headless startup bridge, high-level tools plus a JSX escape hatch, frame capture as images, and render helpers for building and reviewing motion graphics.
How to set it up
- Install Node.js 20+.
- In AE: Edit > Preferences > Scripting & Expressions > enable 'Allow Scripts to Write Files and Access Network'.
- Follow docs/INSTALLATION.md in the repo to install the bridge.
- Register the server in your MCP client and open a project.
This is a plain-English summary of the project's own instructions. Commands and versions change, so always follow the current README at the source link.
Safety notes
- Requires enabling 'Allow Scripts to Write Files and Access Network' in After Effects preferences.
- JSX escape hatch can run arbitrary scripts.
General rule: open a duplicate of your project before letting any agent make changes, and read what a script does before approving it.
