Implementation Reference

• src/mcp_server_aws/server.py:225-229 (handler)

  Handler logic for the 'dynamodb_item_get' tool. Calls boto3 dynamodb_client.get_item() with the provided table_name and key from arguments.

  elif name == "dynamodb_item_get":
      response = dynamodb_client.get_item(
          TableName=arguments["table_name"],
          Key=arguments["key"]
      )

• src/mcp_server_aws/tools.py:213-230 (schema)

  Input schema definition for the 'dynamodb_item_get' tool, specifying table_name (string) and key (object) as required parameters.

  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 'dynamodb_item_get' tool (among others) via the MCP server.list_tools() handler by returning get_aws_tools(), which includes it.

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