[MCU] Does the gov know Tony basically created Ultron? If not, how did Tony keep it under covers?

It's never mentioned in Civil War (as far as I remember) but one would think it would be one of the reasons for establishing the Accords.

It's called the Sokovia Accords. Sokovia was the country Ultron attacked. They made the connection.

One of the specific statues in the Accords is that the creation of any artificial intelligence is strictly prohibited. They go into that aspect on *Agents of SHIELD* with Aida.
