what's interesting about this one is that their claims about what makes slashy different are almost entirely wrong... almost all the big models let you connect and do all of the things mentioned. Not understanding MCP at all is hilarious. If an agent has toosl to access multiple data sources it will make calls across them to resolve things, not sure whatever claiming but there's no way you are actually indexing at scale and probably doing just the exact same thing.
Why wouldn't we be indexing at scale?
the demo video is literally just single thread tool calling to external sources. Indexing data is also a really complex problem more than just adding some elastic search to gmail which also you will find does not scale easily, if that's even what you're doing.
