Implementation Reference

• src/mcp_server_aws/server.py:220-224 (handler)

  The core handler logic for the 'dynamodb_item_put' tool within the handle_dynamodb_operations function. It invokes the DynamoDB client's put_item method using the provided table_name and item arguments.

  elif name == "dynamodb_item_put":
      response = dynamodb_client.put_item(
          TableName=arguments["table_name"],
          Item=arguments["item"]
      )

• src/mcp_server_aws/tools.py:195-212 (schema)

  The input schema definition for the 'dynamodb_item_put' tool, specifying required parameters: table_name (string) and item (object).

  Tool(
      name="dynamodb_item_put",
      description="Put an item into a DynamoDB table",
      inputSchema={
          "type": "object",
          "properties": {
              "table_name": {
                  "type": "string",
                  "description": "Name of the DynamoDB table"
              },
              "item": {
                  "type": "object",
                  "description": "Item data to put"
              }
          },
          "required": ["table_name", "item"]
      }
  ),

• src/mcp_server_aws/server.py:135-140 (registration)

  The list_tools handler registration that returns the list of AWS tools from get_aws_tools(), which includes the 'dynamodb_item_put' tool with its schema.

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