Implementation Reference

• src/mcp_server_aws/server.py:187-193 (handler)

  Executes the dynamodb_table_create tool by calling the AWS DynamoDB create_table API with the provided table_name, key_schema, and attribute_definitions, using pay-per-request billing.

  if name == "dynamodb_table_create":
      response = dynamodb_client.create_table(
          TableName=arguments["table_name"],
          KeySchema=arguments["key_schema"],
          AttributeDefinitions=arguments["attribute_definitions"],
          BillingMode="PAY_PER_REQUEST"
      )

• src/mcp_server_aws/tools.py:120-140 (schema)

  Defines the Tool object including input schema validation for dynamodb_table_create.

      name="dynamodb_table_create",
      description="Create a new DynamoDB table",
      inputSchema={
          "type": "object",
          "properties": {
              "table_name": {
                  "type": "string",
                  "description": "Name of the DynamoDB table"
              },
              "key_schema": {
                  "type": "array",
                  "description": "Key schema for table creation"
              },
              "attribute_definitions": {
                  "type": "array",
                  "description": "Attribute definitions for table creation"
              }
          },
          "required": ["table_name", "key_schema", "attribute_definitions"]
      }
  ),

• src/mcp_server_aws/server.py:135-139 (registration)

  Registers all AWS tools, including dynamodb_table_create, via the MCP server.list_tools() handler by returning get_aws_tools().

  @server.list_tools()
  async def list_tools() -> list[Tool]:
      """List available AWS tools"""
      logger.debug("Handling list_tools request")
      return get_aws_tools()
