ASCII Motion MCP Server

A Model Context Protocol (MCP) server that enables AI assistants to create, animate, and export ASCII art from the ASCII Motion app, using natural language.

What is this?

ASCII Motion MCP allows you to use AI assistants like Claude, GitHub Copilot, and Cursor to:

• 🎨 Draw ASCII art - Create pixel art and text graphics with characters
• 🎬 Animate - Build frame-by-frame animations with onion skinning
• 📥 Import - Convert images to ASCII art with full control
• 📤 Export - Save as PNG, GIF, MP4, HTML, React, or CLI components
• 🌈 Apply effects - Add digital rain, noise, color shifts, and more

All through natural language prompts!

Quick Start

Prerequisites

• Node.js 18+
• An MCP-compatible AI client (Claude Desktop, VS Code + Copilot, Cursor, etc.)

Installation

npm install -g ascii-motion-mcp

Verify installation:

ascii-motion-mcp --help

Client Setup

Important: The --live flag is required for all setups. Without it, the MCP tools have no visual output. After configuring your client, you must also connect the browser to see your AI's work.

Claude Desktop

Add to your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "ascii-motion": {
      "command": "ascii-motion-mcp",
      "args": ["--live", "--project-dir", "/path/to/your/projects"]
    }
  }
}

Restart Claude Desktop after saving.

VS Code with GitHub Copilot

1. Install the GitHub Copilot extension

2. Create .vscode/mcp.json in your workspace:

{
  "servers": {
    "ascii-motion": {
      "command": "npx",
      "args": [
        "ascii-motion-mcp",
        "--live",
        "--project-dir",
        "${workspaceFolder}"
      ],
      "type": "stdio"
    }
  }
}

Or if you've installed globally (npm install -g ascii-motion-mcp):

{
  "servers": {
    "ascii-motion": {
      "command": "ascii-motion-mcp",
      "args": [
        "--live",
        "--project-dir",
        "${workspaceFolder}"
      ],
      "type": "stdio"
    }
  }
}

3. Restart VS Code completely (not just reload window)

4. Open Copilot Chat - the MCP tools should now be available!

Note: VS Code spawns the MCP server automatically when Copilot needs it. You don't run the server manually.

Connect the Browser (Optional)

To see edits in real-time:

1. Ask Copilot: "What is the MCP auth token?"
2. Open ascii-motion.app
3. Click ☰ → MCP Connection
4. Paste the token and click Connect

GitHub Copilot CLI

1. Install GitHub CLI and Copilot extension:

# Install GitHub CLI
brew install gh  # macOS
# or: winget install GitHub.cli  # Windows

# Install Copilot extension
gh extension install github/gh-copilot

# Login
gh auth login

2. Create/edit ~/.config/gh-copilot/config.yml:

mcpServers:
  ascii-motion:
    command: ascii-motion-mcp
    args:
      - --live
      - --project-dir
      - ~/ascii-art-projects

3. Use in terminal:

gh copilot chat "Create an 8-frame animation of a bouncing ball"

Cursor

1. Open Cursor Settings (Cmd+, / Ctrl+,)
2. Search for "MCP" in settings
3. Click "Edit in settings.json" and add:

{
  "mcp.servers": {
    "ascii-motion": {
      "command": "ascii-motion-mcp",
      "args": ["--live", "--project-dir", "/path/to/projects"]
    }
  }
}

4. Restart Cursor

Windsurf

Add to your Windsurf MCP configuration:

{
  "mcpServers": {
    "ascii-motion": {
      "command": "ascii-motion-mcp", 
      "args": ["--live", "--project-dir", "/path/to/projects"]
    }
  }
}

Connect the Browser

After configuring your AI client, you must connect the ASCII Motion browser app to see visual output:

1. Get the auth token - Ask your AI: "What is the MCP auth token?"
2. Open ASCII Motion - Go to ascii-motion.app
3. Open MCP Connection - Click the hamburger menu (☰) → MCP Connection
4. Paste the token - Enter the auth token and click Connect

You should see a green "Connected" status. Now your AI's edits appear in real-time!

Tools not appearing

Restart your AI client after configuration changes. Check that the config file is valid JSON.

Live mode not connecting

• Ensure port 9876 is available
• Check that you're connecting from localhost
• Verify the auth token is correct

No visual output

Make sure you're using the --live flag AND have connected the browser via MCP Connection.
