oversight
Congress can cut the budgets. The President can hire and fire them, and the Courts can find individuals bureaucrats guilt of different things.
deciding which laws of congress are constitutional
The "power of the purse" ---congress can withhold funds from any sector of the bureaucracy which is why the agencies try so hard to influence Congress. In fact, Congress has the power to abolish government agencies and department and eliminate jobs filled by bureaucrats. ( They don't because government workers are also voters and campaigners and there as now so many of them that they can swing elections. Congressmen want to keep their jobs as much as the bureaucrats want to keep theirs. )
Bureaucrats are responsible to many people including the president, Congress, and the voters. So, this would be pretty much everyone.
Executive branch bureaucrats provide Congress with the technical expertise and advice it needs to pass good laws. They also shape the law in the way that they carry out that law and the agency rules that result from it.
There are many kinds of bureaucrats. There is an estimated 4 million bureaucrats in America, working in different positions including secretaries and lawyers and they implement decisions from Congress.
Congress can oversee the Federal Bureaucracy in many ways... 1) They can conduct investigations into an agency suspected of misconduct and can subpoena people for questioning. 2) They can shape the laws that agencies may put into effect 3) Most importantly, Congress has the "power of the purse" meaning they control how much money agencies are authorized to spend and how much money they actually get. Courts on the other hand really only have the power of judicial review over the Bureaucracy, meaning they can declare certain actions unconstitutional.

The federal bureaucracy is under the direction of the President.
There are no middlemen between congress and bureaucracy, they are the same thing. The three levels of government are executive, judicial and legislative.
