Installation

Claude Desktop Setup

1. Clone the repository

git clone https://github.com/yunwoong/aws-nova-canvas-mcp.git

2. 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

3. 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
