About

AE-MCP After Effects Model Context Protocol Server Automate Adobe After Effects with AI through 70+ MCP tools


Overview

AE-MCP is a comprehensive MCP server that enables AI assistants like Claude to directly control Adobe After Effects. It provides 70+ tools covering the full motion graphics workflow — from creating compositions to applying professional effects and expressions.

Key Features

| Feature | Description | |---------|-------------| | 70+ Tools | Complete After Effects automation | | Animation Presets | Spring physics, bounce, elastic, slide, fade | | Expression Library | 20+ pre-built expressions (wiggle, loop, physics) | | Effect Templates | One-click professional looks (cinematic, VHS, neon) | | Motion Graphics | Lower thirds, title cards, transitions, logo reveals | | Reliable Architecture | File-based communication for stability |


Requirements

  • Adobe After Effects 2024 or later
  • Node.js 18+
  • macOS or Windows

Installation

Step 1: Install the MCP Server

git clone https://github.com/anthropics/ae-mcp.git
cd ae-mcp
npm install
npm run build

Step 2: Install the CEP Extension

macOS:

./scripts/install-cep.sh

Windows:

scripts\install-cep.bat

Step 3: Configure Your AI Assistant

Claude Desktop

Add to your config file:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "ae-mcp": {
      "command": "node",
      "args": ["/path/to/ae-mcp/dist/index.js"]
    }
  }
}

Claude Code (CLI)

Add to your MCP settings (~/.claude/settings.json):

{
  "mcpServers": {
    "ae-mcp": {
      "command": "node",
      "args": ["/path/to/ae-mcp/dist/index.js"]
    }
  }
}

Bonus: This repo includes a Claude Code Skill for enhanced After Effects automation. Copy the skill files to your Claude Code skills directory:

cp -r SKILL/* ~/.claude/skills/

The Claude Code skill provides specialized knowledge about After Effects workflows, property formats, and best practices. See [SKILL/SKILL.md](SKILL/SKILL.md) for details.

Step 4: Launch After Effects

  1. Start After Effects 2024+
  2. Open Window > Extensions > AE-MCP
  3. The panel will auto-start and begin listening for commands

Quick Examples

Create an animated intro

Create a 1920x1080 composition called "Intro" at 30fps, 5 seconds.
Add a text layer saying "Welcome" centered on screen.
Apply a slideInUp animation with easy ease.
Add a subtle glow effect.

Build a lower third

Create a modern lower third:
- Name: "Sarah Chen"
- Title: "Lead Designer"
- Blue primary color
- Animate in and out
- 5 second duration

Add physics-based motion

Add a bounce expression to the position of "Logo" layer.
Set amplitude to 0.15, frequency to 4, decay to 6.

Communication Flow

AI Assistant (Claude)
        ↓
   MCP Server (Node.js)
        ↓ Write JSON command
   ~/Documents/ae-mcp-commands/
        ↓ Poll every 100ms
   CEP Extension
        ↓ Execute script
   After Effects DOM
        ↓ Write response
   *.json.response

Troubleshooting

Extension not appearing in After Effects

  1. Verify debug mode is enabled (the install script does this automatically)
  2. Restart After Effects completely
  3. Check extension location:
  • macOS: ~/Library/Application Support/Adobe/CEP/extensions/ae-mcp
  • Windows: %APPDATA%\Adobe\CEP\extensions\ae-mcp

Commands timing out

  1. Ensure the AE-MCP panel is visible in After Effects
  2. Check ~/Documents/ae-mcp-commands/ for command files
  3. Look at the panel's log for errors

Script errors

  1. Open the ExtendScript Toolkit or console in After Effects
  2. Verify composition/layer references exist
  3. Check for ES3 compatibility issues (no arrow functions, template literals, etc.)
