Answer:
You can see Mozart's manuscript, for example concerto in C major:

Besides strings (violins, violas, cellos and double basses), there are "2 oboes, 2 horns, 2 bassoons" etc. A small orchestra. And it's clearly written "Cembalo". I believe it means "harpsichord", not piano.

Cembalo does mean harpsichord, but the harpsichord and piano were used almost interchangeably in Mozart's day.

Here is a good example how Mozart's concertos should be performed:
