How to add a claim to an existing Wikidata item, from command line?

Question

I want to add to Wikidata this claim:

Embassy of Switerland, London - is operated by - Switzerland

... using my Linux command-line.
Launching a web request via curl is OK too.

How to do?

I have seen Wikidata-CLI and Wikidata-sdk, unfortunately they only seem to support read-only operations. None of the external tools listed at Wikidata seem to apply either.

You can use wikidata-agent for that:

curl -XPOST http://your.wikidata.agent.instance/claim -d 'entity=Q5369879&property=P137&value=Q39'

[Update]: you can now actually add claims using wikidata-cli
