Installation

Claude Desktop Setup

  1. Clone the repository
git clone https://github.com/yunwoong/aws-nova-canvas-mcp.git
  1. Configure Claude Desktop
    • Click on Claude > Settings from the Claude Desktop menu.
    • When the popup appears, select Developer from the left menu, and click the Edit Settings button.
    • This will open a folder containing the settings file. The name of this settings file is:
    • claude_desktop_config.json

  1. Add the following content to the settings file (Python version):

    • python version

      "nova-canvas": {
  "command": "uv",
  "args": [
    "--directory",
    "Path to clone folder",
    "run",
    "server.py"
  ],
  "env": {
    "AWS_PROFILE": "YOUR_AWS_PROFILE"
  }
}

      ✅ Only AWS_PROFILE is required. Other variables like AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION, and PORT are optional and not necessary if your AWS profile is set correctly.

      ​ ⚙️ If the setup is completed successfully, you can see that the "nova-canvas" item has been added in Claude > Settings > Developer tab. ⚠️ Important: MCP settings only work on the Claude desktop app, not the Claude web browser version
