Hmm, in that example the MCP server is just a thin api wrapper though, so it wouldn't change anything by running locally, right? Like I could see where maybe a TikTok MCP server would benefit from running locally since that would allow it to expose a camera api, but I can't think of anything you could do with a local Airbnb MCP server that you couldn't do with a cloud one.
Nefariously, I guess since these things would be running in the background continuously, that would provide another avenue for companies to spy on you, so that may be a reason companies create local mcps even if there's no other reason to.
