Usage

Running the Server

You can run the server directly:

python aws_service_reference.py

Using with Claude Desktop

1. Open your Claude Desktop configuration file:

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

2. Add the server configuration:

{
    "mcpServers": {
        "aws-service-reference": {
            "command": "python",
            "args": ["/ABSOLUTE/PATH/TO/aws_service_reference.py"]
        }
    }
}

Replace /ABSOLUTE/PATH/TO/ with the actual path to where you saved the server file.

1. Restart Claude Desktop

Available Tools

The server provides four tools:

1. list_aws_services: Lists all available AWS services
2. get_service_actions: Gets API actions for a specific AWS service
3. get_action_condition_keys: Gets condition keys supported by a specific API action
4. get_action_resource_types: Gets resource types supported by a specific API action

Example Usage in Claude

Once connected, you can ask Claude questions like:

• "What AWS services are available?"
• "Show me all the API actions for the S3 service"
• "What condition keys are supported by the s3:PutObject action?"
• "What resource types can I use with the ec2:RunInstances action?"
