Implementation Reference
- src/mcp_server_aws/server.py:225-229 (handler)The core handler logic for the 'dynamodb_item_get' tool.

- src/mcp_server_aws/tools.py:213-230 (schema)Tool schema definition including name, description, and input schema requiring 'table_name' (string) and 'key' (object). This defines the expected input structure for validation.Tool( name="dynamodb_item_get", description="Get an item from a DynamoDB table", inputSchema={ "type": "object", "properties": { "table_name": { "type": "string", "description": "Name of the DynamoDB table" }, "key": { "type": "object", "description": "Key to identify the item" } }, "required": ["table_name", "key"] } ),
- src/mcp_server_aws/server.py:136-140 (registration)Registers the tool list with the MCP server by returning get_aws_tools(), which includes the dynamodb_item_get tool from tools.py.async def list_tools() -> list[Tool]: """List available AWS tools""" logger.debug("Handling list_tools request") return get_aws_tools()
