Installation
Here are some ways you can work with MCP across AWS, and we'll be adding support to more products including Amazon Q Developer CLI soon: (e.g. for Amazon Q Developer CLI MCP, ~/.aws/amazonq/mcp.json):
{
"mcpServers": {
"awslabs.nova-canvas-mcp-server": {
"command": "uvx",
"args": ["awslabs.nova-canvas-mcp-server@latest"],
"env": {
"AWS_PROFILE": "your-aws-profile",
"AWS_REGION": "us-east-1",
"FASTMCP_LOG_LEVEL": "ERROR"
},
"disabled": false,
"autoApprove": []
}
}
}
or docker after a succesful docker build -t awslabs/nova-canvas-mcp-server .:
# ficticious `.env` file with AWS temporary credentials
AWS_ACCESS_KEY_ID=ASIAIOSFODNN7EXAMPLE
AWS_SECRET_ACCESS_KEY=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
AWS_SESSION_TOKEN=AQoEXAMPLEH4aoAH0gNCAPy...truncated...zrkuWJOgQs8IZZaIv2BXIa2R4Olgk
{
"mcpServers": {
"awslabs.nova-canvas-mcp-server": {
"command": "docker",
"args": [
"run",
"--rm",
"--interactive",
"--env",
"AWS_REGION=us-east-1",
"--env",
"FASTMCP_LOG_LEVEL=ERROR",
"--env-file",
"/full/path/to/file/above/.env",
"awslabs/nova-canvas-mcp-server:latest"
],
"env": {},
"disabled": false,
"autoApprove": []
}
}
}
NOTE: Your credentials will need to be kept refreshed from your host
Installing via Smithery
To install Amazon Nova Canvas MCP Server for Claude Desktop automatically via Smithery:
npx -y @smithery/cli install @awslabs/nova-canvas-mcp-server --client claude
AWS Authentication
The MCP server uses the AWS profile specified in the AWS_PROFILE environment variable. If not provided, it defaults to the "default" profile in your AWS configuration file.
"env": {
"AWS_PROFILE": "your-aws-profile",
"AWS_REGION": "us-east-1"
}
Make sure the AWS profile has permissions to access Amazon Bedrock and Amazon Nova Canvas. The MCP server creates a boto3 session using the specified profile to authenticate with AWS services. Your AWS IAM credentials remain on your local machine and are strictly used for using the Amazon Bedrock model APIs.
remote-capable server
The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.
Provides image generation capabilities using Amazon Nova Canvas through Amazon Bedrock, enabling the creation of visuals from text prompts and color palettes—perfect for mockups, diagrams, and UI design concepts.
