Flying Wonder can take no Actions?

The flying wonder is here:  https://www.dndbeyond.com/magic-items/10771765-mechanical-wonder

The stat block has nothing listed under "Actions" and  Bonus Actions only say it can "Chime" and "Sprint".

Usually stat blocks list the things a creature can do and the creature can only do whats on the statblock.  Clearly that cant be true of the flying wonder because reading the stat block thay way would say it cant do anything.

On top of that it cant speak and doesnt have a telepathic link like a familiar.

So what can a flying wonder do?

Any creature can take any of the normal actions (and bonus actions or reactions) listed in the Actions section in the PHB. Or they can do whatever actions they (in this case you, since they follow commands) improvise up and the DM says yes to (also mentioned in the Actions section). Or they can perform any actions that are defined in their statblock.

Thezzaruz is correct, and if you're looking for support for that in the rules, you can find it in the description of how a stat block works in the Monster Manual (here).

Usually, the specific Actions in that section of a monster's stat block are melee attacks, ranged attacks, spell attacks, spellcasting, and saving throw effects, though there are exceptions (e.g. Celestial Spirit).

To me, a Flying Wonder probably doesn't have any of those actions because it's not thematic. But as folks mentioned, it's possible to do what they explained, and even make an Opportunity Attack:

What actions can monsters use to make Opportunity Attack? Are Multiattack and breath weapon actions allowed?

When making an Opportunity Attack, a monster can make any single melee attack listed in its stat block. A monster also has the option to make an Unarmed Strike as an Opportunity Attack, following the normal rules of an Unarmed Strike. [...]

Hmmm.. 

My artificer might be building one of these from plans, and giving it a wand of magic missile which is also built from plans.

With like 2hitpoints, its doa on any hit, but a couple of magic missiles strikes could help any fight. It also doesnt cost 100 gold like the homunculus.

Blind sight to 60 feet is tight!

Should work but it would be a clear target if it starts doing magic attacks and at 12 AC and 2 hp I don't see it having much survivability. 

Another consideration is that it is a creature and can wear and use magic and normal items as well as be targeted by effects, depending on how much you want to invest in protecting it.

Potions of Invisibility + Flying Wonder and a spell-storing item with a non-damaging effect that doesn't require an attack roll is relatively safe... as long as there are no AoEs.

Most likely, it's just going to be a disposable, legally distinct Amazon drone.
