Installation

Setting Up With Claude Desktop

1. Configure Claude Desktop:

   • Click on Claude > Settings from the Claude Desktop menu
   • Select Developer from the left menu, and click the Edit Settings button
   • This opens a folder containing the claude_desktop_config.json settings file

2. Add the Nova Canvas configuration:

"nova-canvas": {
  "command": "uvx",
  "args": [
    "aws-nova-canvas-mcp"
  ],
  "env": {
    "AWS_PROFILE": "YOUR_AWS_PROFILE"
  }
}

Note: Only AWS_PROFILE is required. Other variables like AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION, and PORT are optional if your AWS profile is configured correctly.

Once setup is complete, you'll see the "nova-canvas" item added in Claude > Settings > Developer tab.

Image Storage Location

Generated or edited images are automatically saved to:

• macOS / Linux: ~/Desktop/aws-nova-canvas
• Windows: C:\Users\YourUsername\Desktop\aws-nova-canvas

The application automatically creates this folder if it doesn't exist.

Usage

Once configured, you can access Nova Canvas features directly through your Claude Desktop application. You can generate images from text prompts, edit existing images using inpainting or outpainting, create variations of images, and apply color guidance to your generations.

Limitations

• Prompt text has a 1024 character limit
• Image generation supports up to 3 images at a time
• Image variation requires 1-5 reference images
• Color guide supports 1-10 color codes

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "nova-canvas" '{"command":"uvx","args":["aws-nova-canvas-mcp"],"env":{"AWS_PROFILE":"YOUR_AWS_PROFILE"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "nova-canvas": {
            "command": "uvx",
            "args": [
                "aws-nova-canvas-mcp"
            ],
            "env": {
                "AWS_PROFILE": "YOUR_AWS_PROFILE"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

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

2. Add this to your configuration file:

{
    "mcpServers": {
        "nova-canvas": {
            "command": "uvx",
            "args": [
                "aws-nova-canvas-mcp"
            ],
            "env": {
                "AWS_PROFILE": "YOUR_AWS_PROFILE"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
